Why did carbon dioxide emissions became abnormally high in 1945?
Carbon dioxide emissions became abnormally high in 1945 due to a combination of factors. The end of World War II led to a rapid increase in industrial production and the use of fossil fuels. Additionally, the expansion of the global transportation system, including the use of airplanes and automobiles, contributed to the higher emissions.
What led humans to burn fossil fuels?
They discovered coal could burn longer than wood. They used it to drive steam engines which could power vehicles and factories. At that time nobody knew about carbon dioxide emissions and how they cause global warming.
What element from the periodic table is used to make pencils?
Pencils are filled with Graphite, they used to be filled with led but since led is Poisonous they replaced the led with graphite.
What do plants do with CO2 present in the atmosphere?
It is used in the light independent reaction of photosynthesis where it is combined with a 5-carbon molecule called ribulose bisphosphate using an enzyme to form two molecules of the 3-carbon molecule called glycerate-3-phosphate. This is then reduced by ATP and reduced NAD from the light dependent reaction into two molecule of triose phosphate, some of which is then converted to organic substances such as glucose. This is how energy enters an ecosystem and then consumers and herbivores take up this energy by eating the plant or another animal who has eaten the plant and thereby obtaining the glucose. they use it for energy in photosynthesis and it is converted into carbohydrates- or sugars- because they, unlike us can create their own energy, we just use it
How long it takes for pencil led to kill you?
Pencil lead is graphite. No lead is actually in pencils. If it is stabbed through your eye, it will kill you instantly. If you heat it to 4200 celcius, it will turn to carbon vapor, which when cooled, will become carbon dioxide or carbon monoxide, killing you In a few minutes. If shot at a micron/sec under the speed of light, it will destroy your planet. If you breath gigatonic amounts of it, you might get lung cancer in a few decades. If you eat it, it will not digest, but that is it.
What observation led jean senebier to develop his theory?
It showed that fixed air is carbon dioxide.
Why descover carbon dioxide?
carbon dioxide of coarse is able to kill a person so scientists are finding gases liquids and solids that are able to kill people and in doing so help prevent it like led if it got inside you you could die but it depends on the dose of the led that entered your body. and carbon dioxide is good too it helps vegetation grow. so it is bad and good but i still wont go sticking your head in a all rich carbon dioxide environment.
What are carbon dioxide planets?
Both Venus and Mars have carbon-dioxide atmospheres. The Earth also started with a carbon-dioxide atmosphere but the development of anerobic bacteria produced oxygen as a waste-product which eventually altered the atmosphere and killed off the bacteria but allowed other types of organism using oxygen to develop, and that eventually led to animal life.
What human activities have led to increasing levels of carbon dioxide in the atmosphere?
one of them is people drive cars another is globle warming
What happened to the earth's climate after Rodinia broke up?
With the break up of the supercontinenent, Rodinia, there were of course many smaller continents which led to more rainfall and consequently less carbon dioxide in the atmosphere (since rain "washes" the carbon dioxide out of the atmosphere). As a result of less carbon dioxide in the atmosphere, temperatures dropped and ice began to form in polar regions.
Where has the carbon dioxide in the atmosphere gone?
well in a way it hasn't gone at all, i mean there's still carbon dioxide in the air, it's part of the gas called'air' so yeah. but if not, it goes into a plant, since plants use it for photosynthesis, which is the process of making their own food. that's why plants are producers in the food chain/ web

What increases the Earth's temperature?
the enhanced greenhouse effect. An increase in the concentration of greenhouse gases in the atmosphere results in more heat being retained and an overall warming of the Earth's temperature. Although they make up a small percentage of atmospheric gases, changes in the concentration of greenhouse gases have a huge effect on the balance of natural processes. The core concern about climate change is human potential to alter the climate through activities that are a result of our way of life and how we treat the natural environment. There have been significant technological advances over the past 60 to 100 years that have offered humankind countless benefits and conveniences. These increases in human activity, however, have also led to an additional release of greenhouse gases that have placed stress on natural processes. Some of the gases, such as carbon dioxide, water vapour, methane, nitrous oxide, and ozone are the result of both natural and human processes. Others, notably fluorinated gases, are generated solely by human activities. The sources of these gas emissions include burning fossil fuels to power our way of life, industrial processes, urbanisation and land use, agriculture and deforestation. Since the beginning of the industrial revolution, concentrations of carbon dioxide in the atmosphere have increased nearly 30 per cent methane concentrations have more than doubled, and nitrous oxide concentrations have risen by about 15 per cent. Carbon dioxide is the single largest contributor to the enhanced greenhouse effect. Increases in carbon dioxide emissions account for approximately 70 per cent of the enhanced greenhouse effect. Using ice cores from the Antarctic, scientists estimate that the concentration of carbon dioxide in the atmosphere in the pre-industrial era had a value of approximately 280 parts per million (ppm). Measurements in 2005 put it at 379 ppm. The 2005 figures also tell a story of alarming growth. The 2005 carbon dioxide levels exceeded the natural range of atmospheric carbon dioxide over the last 650,000 years (180 to 300 ppm). In addition, even though there has been year to year variability (at an average of 1.9ppm), the annual growth rate of carbon dioxide concentrations in the atmosphere was larger during the 10 years between 1995 and 2005 than it had been since the beginning of continuous direct atmospheric measurements between 1960 and 2005 (average: 1.4 ppm per year) (IPCC, 2007).
Which scientist showed that light was needed for photosynthesis to happen?
In 1796 a Swiss botanist, Jean Senebier, showed that plants consume carbon dioxide and produce oxygen in the presence of light. His research was preceeded by the research of others who led the way to the final discovery.
What is the mineral for a pencil led?
Carbon (C) or more specifically, Graphite.
What mineral makes a pencil led?
Graphite, which is a form of crystalline carbon.
What event led to a major in balance in the carbon cycle?
The industrial revolution
