Causes of Chemicals
What does carbon dioxide do?
It warms the Earth.
Does traveling by airplane increase global warming?
Yes.
What is the long term appearance shape of data called?
trend.
general weather patterns over a long period of time
climate
Climate researchers in Greenland can use ice core samples to tell them about methane in the atmosphere in the past. Researchers found a sample that showed a time period when methane in the atmosphere increased. What happened to the amount of energy absorbed by Earth's surface during this time?
During this time, the amount of energy absorbed by Earth’s surface…
increased
What does methane do?
Heats up the Earth.
What causes the most combustion?
Power plants.
Fluctuations.
the ability to make things move or change
energy
Geologists have found rocks showing that about 700 million years ago, there was a time period when the amount of carbon dioxide in the atmosphere decreased. How did energy in the Earth system change during this time?
There was less energy in the Earth system and less energy absorbed by Earth’s surface, because less energy entered than exited.
What does Sulfur Dioxide do?
It cools the Earth.
What is the main factor of the increase in methane?
The increase in demand for cows/beef.
a molecule made of carbon and oxygen atoms
carbon dioxide
a measure of how hot or cold something is
temperature
Scientists have tools that measure the amount of energy entering and exiting the Earth system. Recently, more energy entered the system than exited. What might scientists expect to see in the atmosphere, and what has changed about energy in the Earth system during this time?
Methane increased, leading to more energy in the Earth system and more energy absorbed by Earth's surface.
What does Nitrogen dioxide do?
Nothing.
Does driving electrical cars entirely cause no carbon dioxide?
No, because the electricity is mainly gained by the release of CO2 from power plants.
To take in
absorb.
the mixture of gases surrounding a planet
atmosphere
Fossilized shells from the Pacific Ocean show that about 15 million years ago, there was a time period when carbon dioxide in the atmosphere increased. What would have happened to the energy absorbed by Earth’s surface during this time?
During this time, energy absorbed by Earth’s surface…
Increased
What does ozone do?
decrease UV light to prevent skin cancer, and barely affects the temperature to rise.
What could decrease or resist the temperature increasing the most reasonably? And what do you do with it to work?
Power plants, it works by replacing the power plants, since we still need to match electricity demand by the citizens and foreigners, we have to replace it into solar, wind, hydro, and nuclear power.
What humans do to contribute to global warming.
Human activities.
a molecule made of carbon and hydrogen atoms
methane
Ice core data from Greenland indicates there was a time period on Earth when the atmosphere changed so more energy entered the Earth system than exited. What change to the atmosphere could have caused this, and how would it have affected energy on Earth during that time?
Carbon dioxide increased, leading to more energy in the Earth system because more exiting energy was redirected (bounced) back toward Earth.
