Is glass renewable or non renewable resource?
Yes, technically speaking it is. A range of glasses are found in—and formed by—nature. Through volcanoes, the act of time, micro-organisms, and lightning. So technically speaking it is a natural resource, in the eyes of most scientists. So even though, I am a trilingual speaking kid, I got a more researched answer, than these washed-out old boomers, that don't understand modern science.
It is false that hydro is the least widely used. There are many renewable energy sources, and hydro power is one of the most commonly used, with many installations all over the world. Unconventional renewable power sources that have been used include such ideas as extracting energy from the impact of people's feet as they walk on sidewalks, which is just one of many examples of sources less commonly used than hydro.
Why would you call someone a donkey?
When you call a person a donkey it might be you want to insult them alright.but it might be a compliment:a new group of young elite are now called dnkys although some pronounce it has donkee but actually it's pronounced dee en kee. What is a dnky? It is a group name for strong youths who share a mutual relationship and are very intelligent... In yoruba:donkey(or horse) is often to describe someone with strong agility in sex.
What is a danger to the environment?
the ff. threats to the environment are:
+indiscriminate logging
+kaingin system
+Human settlements
+deforestation etc.
Why grass is greener under a tree?
Grass tends to be greener under a tree due to competition for sunlight. The tree's leaves block sunlight from reaching the grass, causing it to receive less light and grow more slowly. Additionally, trees release nutrients into the soil as their leaves decompose, which can benefit the grass growing beneath them.
How was the environment of the megalodons?
This is a very difficult question to answer, for two main reasons:
a) C. megalodon lived for over 20,000,000 years, and a lot happened in earth's marine and climatic environements during such a long period of time.
b) Paleoclimatologists are still trying to understand the complexity of climate changes during the Cenozoic era which, in turn, directly affected the oceans currents, temperatures, salinity, etc.
C. megalodon appears in the fossil register in the Late Oligocene, when temperatures began to rise after the Early Oligocene abrupt temperature decline (the first time in the Tertiary era that Antarctica was covered by ice).
During Late Oligocene, Antarctica was linked to Australia AND to South America, but Panama Isthmus did not existed yet. This means a totally different oceanic current worldwide system from today's oceanic currents. The Pacific and Atlantic oceans were connected, and no ocean conveyor belt existed.
During the next period, the Miocene, temperatures became warmer, and Antarctica lost its ice cap.
In the Miocene, cetaceans reached its highest diversity, and it was a flourishing period for the megalodon, because of abundance of food and warm oceanic water.
But the megalodon at that time shared the top of the food chain with another formidable apex predator, the Livyatan melvillei, its «Nemesis».
This predatory odontoceti cetacian could reached the same size of extant sperm whales, or could be even larger. Confirmed lenght of more than 17 metres is accepted today by paleontologists, but VERY FEW fossils of this apex predatory whale were found. Larger individuals are a probabilistic certitude.
Moreover, Livyatan melvillei had not only teeth in BOTH upper and lower jaws - unlike today's sperm whales - but they had much larger teeth than megalodon (36 cm lenght, confirmed).
The Middle Miocene extinction reached its peak, and a wave of extinctions of marine life diminuished megalodon food supply. Neverthless, the megalodon thrived.
In the Late Miocene temperatures droped again, and Antarctica suffered a glaciation.
In colder waters, more cetaceans became extint, including the mighty Livyatan melvillei. However, C. megalodonsurvived without a significant decrease of population.
The next period, the Pliocene, arrived and temperatures kept dropping. Whale species became much larger, some reaching or exceeding the size of the extant blue whale.
C. megalodon, beeing a warm blooded shark, adapted the best he could to colder oceans, although he prefers warm waters. It changed its prey attack behavior to feed on larger whales, and became also larger and adopted a more brutal attack to the new preys.
The Drake Passage opened and Australia is no longer attached to Antarctica.
North and South Americas are now connected, and the Pacific/Atlantic connection is over, except through the difficult and cold Drake Passage. The Isthmus of Panama made the end of the final remnant of what was once essentially a circum-equatorial oceanic current, for tens of millions of years.
Megalodon populations from the Pacific loose contact with the Atlantic populations, which became reduced to relic populations over time.
The Pacific is much, much larger and megalodon is now the only apex predator in the top of the food chain. Life is good for the megalodon in the warm Pacific.
But the new Pleistocene period brings something that will put an end of more than 20 million years of C. megalodonocean dominance: the severe Quaternary glaciations.
However these glaciation periods are more severe in the northern hemisphere, and each glaciation has a warm interglacial period.
Megalodon's populations are greatly reduced, even in the Pacific. But the monstruous shark is tough, and in 1.5 million years BCE it is still hunting ferociously any prey he can eat.
But his time must come to an end, as all species do.
Reduced to isolated relic populations in the Pacific ocean, smaller males are fewer, because of cannibalism. The larger megalodon females still try parthenogenesis to avoid the extintion.
But this is not enough.

What potent greenhouse gas is trapped in large quantities in the permafrost of the tundra?
Unfortunately, this potent greenhouse gas - METHANE - is no longer Trapped!
What is the effects of season on livelihood of people?
Seasons can affect people's livelihood by impacting activities such as agriculture, tourism, and outdoor labor. For example, farmers rely on certain seasons for planting and harvesting crops, while tourism businesses see fluctuations in visitors based on weather. Additionally, extreme seasonal conditions like hurricanes or droughts can disrupt livelihoods by damaging infrastructure or natural resources.
What is a resource-based settlement?
A resource-based settlement is a type of community that is established near valuable natural resources, such as minerals or forests. These settlements often rely on the extraction and processing of these resources for economic activities and livelihoods. Development and sustainability of resource-based settlements are closely tied to responsible management of the natural resources they depend on.
What two groups are natural resources grouped into?
Renewable resources and non-renewable resources. Renewable resources can be replenished over time, such as sunlight and wind. Non-renewable resources are finite and will be depleted over time, like fossil fuels and minerals.
What are green house gases or atmospheric gases?
Atmospheric gases trap heat so that Earth is not a frozen wasteland. Greenhouse gases is the term used to refer to heat-trapping gases such as carbon dioxide and methane because these gaseous components of the atmosphere make Earth function like a greenhouse-heat from the Sun that is reflected off the Earth is reflected back up to the atmosphere and the greenhouse gases trap some of this heat.
Understand that greenhouse gases are necessary to retain some of the Sun's heat, but they are bad in excess; to much carbon dioxide( a greenhouse gas) contributes to global warming-too much heat from the Sun is trapped by the atmosphere so that temperatures on the surface rise.
What was the impact of changes on the society and environment of the industrializing countries?
The impact of changes are. People get employments in different fields and in different qualifications. The workers also obtain housing and they are paid accordion to their wages,there are also good treatment ,and good water for drinking, transportation.
Why you should concerned about the environment?
because the environment is the place where we live and if we are not concerned everything will come over our heads and we will be in great trouble!
Would you be willing to eat lower on the food chain in order to decrease your ecological footprint?
Which one is best ?a)Yes, but only if the extra food was sent to countries with starving people.
b)Yes, because it would decrease environmental degradation.
c)I don't eat meat now.
d)No, I don't see the need to eat lower on the food chain.
e)No, I like the taste of meat too much.
How important is wind to humans?
wind is important to humans because 1. it can be used to make electricity 2. it moves seeds that grow to keep the enviroment going 3.it is inexhaustible so it will never run out. wind helps power things that we are running out of other resources to power
How can you restore the environment if it has been damaged or destructed that way?
Restoring the environment post damage involves activities like reforestation, habitat restoration for wildlife, cleaning up polluted areas, and promoting sustainable practices. Collaborative efforts from governments, organizations, and communities are crucial for long-term restoration efforts to be successful. Implementing policies that prioritize conservation and sustainability can also help prevent similar damage in the future.
Does a volcano have an impact on the environment or humans?
A volcano has an impact on both the environment and humans. It has an impact on the environment because it would kill all of the plants and scorch the Earth. It would have an impact on humans because if a human civilization lived there, it would wipe out their whole city.
What types of activities could a a human community more sustainable?
Everyone should sleep more relax more. Maybe 10 to 12 hours a day. Give us less time to waste resources. And it easy to make this change. Rational thinking for a new world.
Harvesting is important to gather crops at the peak of their ripeness, ensuring optimal flavor, nutrition, and quality. It also allows farmers to efficiently use resources such as water, land, and labor, contributing to food security and sustainability. Additionally, harvesting provides income for farmers and supports local economies.
Where does the greenhouse effect occur?
The greenhouse effect occurs in the Earth's atmosphere. Greenhouse gases such as carbon dioxide and methane trap heat from the sun, leading to warming of the Earth's surface. This process is essential for maintaining the planet's temperature suitable for life.
What people do that can affect the environment?
People can affect the environment by polluting air and water, deforestation, overfishing, and producing excessive waste. These actions can lead to habitat destruction, climate change, and loss of biodiversity, impacting ecosystems and the health of the planet.
The Sierra Club was established as an advocate for which political movement?
The Sierra Club was established as an advocate for the environmental conservation movement. It focuses on protecting and preserving natural areas and ecosystems, promoting responsible stewardship of the environment, and advocating for policies that prioritize environmental protection.
How long does a glass of water take to evaporate on windy days?
Specific rates of evaporation can only be measured when one knows the exact measurements of those energies and factors that bear influence upon it: air flow, temperature (of air, container, as well as actual water at time evaporation), concentration of impurities in the water, concentration of substances in the air, actual air pressure (evaporation takes less time in areas of low pressure), the actual surface area and concentration of the water to be evaporated, any known inter-molecular forces, as well as the true density of the water being measured.
All that being said, simple measurements can be made using an instrument called an "atmometer" or "evaporimeter," which can actually be fairly simply made so that a non-complex experiment can be performed to get a general rate of evaporation for your area.
The experiment requires the use of local tap water and porous filter paper, which will be used to draw the water from any measured glass cylinder into which a wick has been carefully placed. The wick can be made of any number of things- paper, cloth, string, and other similar goods that will actually allow the water to be drawn through it. As water evaporates from the surface, it will draw water from the cylinder onto the filter paper through use of the wick by simple capillary action. The more water that evaporates from the filter's surface, the more water will be drawn from the cylinder. By the taking of periodic measurements of the water that remains in the cylinder, and repeating the experiment a number of times, enough so that an average time can be formed, a rate of evaporation can be rather easily established. This rate will only be true for this one area at the time the experiment is performed, but it will give you a general idea of the rates of evaporation in this one specific area
What happens when there is a lot of carbon dioxide in the Atmosphere?
The Earth would be unable to radiate energy away from itself at a rate, sufficient to maintain an energy balance. Earth would become warmer and warmer until something happened to bring the energy cycle back into balance, like another year without summer or an increase in Earth's CO2 sequester rate.
Increased levels of atmospheric CO2 are already a reality, but the net effect this has on warming is very difficult to quantify. Scientific inquiries, concerning this and other warming issues, are ongoing.
Carbon dioxide absorbs, and releases heat. To over simplify: The CO2 in the air allows heat to radiate from the sun to the earth. However, CO2 interferes with the heat that is radiated by the earth into space. It absorbs this radiation and releases some of it back to the earth.
Over time, if this condition is allowed to continue and to evolve, it results in a warming shift in Earth's energy balance, a net gain in energy (heat) for earth and its atmosphere.
