What causes carbon dioxide in the atmosphere to increase?

Carbon dioxide is known to help keep our planet warm and is a minor contributor to the overall warming of the planet. Current levels are around 0.037% which is questionably up from a 1000 year low in 1850 of 0.028%. This change has been consistent with past records of warming trends. CO2 follows temperature rises by 20 to 800 years. These increases help plant life.

A:Increased concentration of carbon dioxide in the atmosphere causes Global Warming.

How much energy is saved when Steel is recycled instead of mined?

Recycling steel and iron saves 75% of the energy needed to make it from iron ore. Every year America saves enough from recycling steel to provide Los Angeles with electricity for ten years! Or 18 million households for one year!

In 1996 US Steelmakers remelted almost 19 billion steel cans (58% of all cans sold)! That's about 600 steel cans every second.

How is the greenhouse effect important to the earths ecosystem?

The greenhouse effect is important because it helps keep Earth warm enough to support life by trapping heat from the sun in the atmosphere. Without the greenhouse effect, Earth would be much colder and uninhabitable. However, human activities have intensified the greenhouse effect, leading to global warming and climate change.

What is the problem with using traditional sources of energy?

Present energy sources, such as coal and oil are fosslis fuels which mean they are limited. Because they will run out people will have to find another way of getting energy, such as wind or solar, to keep ever thing going Present energy sources, such as coal and oil are fosslis fuels which mean they are limited.

How does a cast fossil form?

When the animal dies its skeleton settles on the sea floor and is buried by sediment. that thickens and begins to turn to stone. The skeleton dissolves and a mold is formed. Minerals crystallize inside the mold and the cast is formed.

Why is the balance in nature necessary?

Balance in nature is important mostly because if the food chain. If something else didn't exist, like a carnivore for example, the animals they prey on would become overpopulated. All animals also have a purpose in nature, so the world would not be right if any one animal was not there. Everything in nature effects another thing, so balance in nature is very necessary.

How can improved agriculture and forestry help reduce greenhouse gas emissions?

Cattle belch out a lot of methane (CH4), which is also emitted from rice paddy fields. Scientists are working to improve both these practices with the aim of reducing the amount of methane emitted. Reforestation and afforestation will also remove more carbon dioxide (CO2) from the atmosphere.

How can local councils help to reduce carbon emissions?

Local councils can reduce carbon emissions by implementing policies that promote sustainable transportation options like biking and public transit, investing in renewable energy sources for local government operations, and launching awareness campaigns to educate residents on energy-saving practices. Additionally, councils can support initiatives to increase green spaces and promote energy-efficient building practices within the community.

Is nickel a non renewable resource and why?

Nickel is considered a non-renewable resource because it is a naturally occurring mineral that is finite in quantity on Earth. Once mined and extracted, nickel cannot be replenished within a human lifetime due to the slow geological processes involved in its formation. Therefore, it is important to use nickel efficiently and explore alternative sources to minimize depletion and environmental impact.

What are the methods of germplasm conservation and which is the best?

The methods of germplasm conservation include seed banks, field gene banks, in vitro conservation, cryopreservation, and DNA banks. The best method depends on the type of germplasm being conserved, as well as factors like cost, long-term viability, and ease of access. A combination of methods is often used to ensure comprehensive conservation of germplasm.

What is the difference between staying and living?

Staying only means staying in a certain places during certain times of the day, like sleeping in a hotel, being in school etc. Living means doing things in a certain place. You sleep, eat, interact and live in a place. This is usually places like your home.

If bees disappear what will happen?

If there are still eggs or larvae less than a couple of days old in the brood comb when the workers realize the queen has gone, they can draw a cell out into a queen cell and feed the larva with royal jelly. This will then develop into an new queen. In practice they will probably do this to several eggs.

If there are no eggs, or if the only eggs are drone eggs there will be no bees to replace the current generation and the colony will die out within a month to six weeks.

What important role do snakes play in your environment?

Snakes play a crucial role in the environment as predators, helping to control populations of rodents and other small animals. They are also important in maintaining the balance of ecosystems by serving as prey for larger animals and contributing to nutrient cycling when they decompose after death.

Are natural disasters a big problem in the world?

Yes, natural disasters can be a significant problem in the world due to their destructive impact on communities, causing loss of lives, displacement of populations, and economic damage. Climate change is also contributing to an increase in the frequency and severity of natural disasters, making it an even bigger concern for global populations.

What adaptations give flowering plants a reproductive advantage over gymnosperms?

Flowering plants have coevolved with pollinators, which increases the efficiency of pollination and fertilization. They also produce fruits that aid in seed dispersal, allowing them to colonize new habitats more effectively than gymnosperms. Additionally, the reduced gametophyte generation in flowering plants increases reproductive success by protecting the developing embryo.

What is meant by the term greenhouse gas listing the three most significant ones?

A greenhouse gas is any gas in our atmosphere that is capable of absorbing heat from incoming or out going radiation. They normally will be gases with three or more molecules.

The three most significant green houses gases and the amount they contribute are water vapor (80%), carbon dioxide (6%) and methane (1%). Nature produces 99.7% of all green house gas emissions.

How did the people clean up after the eruption from the nevado del Ruiz?

After the eruption of Nevado del Ruiz in 1985, people helped clean up by removing ash and mud from their homes and streets, rebuilding infrastructure, and assisting in the recovery and relocation of affected communities. International aid and government assistance also played a role in the cleanup efforts.

Is aluminum a product or a energy?

Aluminum is a product that is widely used in various industries for its lightweight, malleable, and corrosion-resistant properties. It is produced from bauxite ore through an energy-intensive process that requires a significant amount of electrical energy.

Tell what you know about Coelacanths?

The coelacanths are a primitive form of fish related to lungfishes and tetrapods They have been present in the Earth's oceans since the end of the Cretaceous period. They are presently found in the Comoros, Kenya, Tanzania, Mozambique, Madagascar, and in iSimangaliso Wetland Park, Kwazulu-Natal in South Africa. With this distribution the number of individual fish is probably in the hthousands.

How Do rabbits adapt to the environment?

Rabbits adapt to their environment by burrowing to create underground tunnels for shelter, staying hidden from predators during the day, and camouflaging their fur to blend in with their surroundings. They are also able to reproduce quickly to ensure the survival of their species in challenging conditions.

When a maggot grows up what does it become?

A maggot grows up to become a fly. Maggots are the larval stage of flies, which eventually pupate and emerge as adults.

How can human activities affect the earth's system?

Another contributor wrote:

Humans are polluting the environment and causing damage to natural ecosystems by things such as deforestation and air pollution. Human activities are mainly disrupting natural cycles such as the carbon cycle. Humans are emitting extra extra carbon dioxide into the air and cutting down trees that absorb carbon dioxide and emit oxygen. So basically the earth had a stable biosphere right up until the industrial revolution. That's when people started using more machines. The environment has a very delicate balance, after the industrial revolution people started using more resources, producing more waste, damaging the air and water and overall disrupting the balance of the environment. Though unfortunately this wasn't realized until recent times. Scientists are working on ways to help protect the environment but they still have a long way to go. And also a lot of big companies and powerful people don't want to use a lot of today's alternatives because they are worried about loss of money and power.

What do langurs eat?

A silver langur is also known as a silver leaf monkey that is found in S.E. Asia.

Is a cast fossil one kind of carbonized fossil?

No, a cast fossil is not the same as a carbonized fossil. Cast fossils are formed when minerals fill in the cavity left by a previously existing organism, while carbonized fossils are formed when organic materials are compressed and heated, leaving a carbon residue of the original organism. Both types of fossils preserve the shape of the organism, but through different processes.
