Decreasing temperature rates
Why are too many greenhouse gases bad for the environment?
They cause trees to die.
They release heat and will be the cause of the next ice age.
They trap heat in our atmosphere causing the planet to warm up.
They are fossil fuels which pollute our environment.
Which one is not a fossil source?
petrol
sun
coal
natural gas
What is a flammable gas that forms from decaying organic matter and material in land fills?
methane
propane
oxygen
carbon
The trapping of thermal energy in the atmosphere when solar energy that was absorbed by Earth is re-radiated into the atmosphere is called the _______________ ______________.
carbon dioxide
greenhouse effect
air pollution
ozone layer
This is a greenhouse gas released into the atmosphere from farms that apply large amounts of nitrogen-based fertilizers to help crops grow.
nitrous oxide
carbon dioxide
H2O
greenhouse gasses
Fuel formed in the Earth from animal and plant remains is called ___________ ___________.
carbon dioxide
nitrous oxide
fossil fuels
climate change
Any changes to the overall climate of the Earth over several years is ___________ _____________.
greenhouse gasses
climate change
carbon dioxide
nitrous oxide
This molecule is made from two atoms of oxygen and one carbon atom. This is also produced from breathing and burning certain substances called fossil fuels.
CFC
UV
H20
CO2
If greenhouse gases in the atmosphere increase, Earth's temperature will __________________.
increase
decrease
stays the same
all of these are correct
How did scientists gather information about the atmosphere in the time of the dinosaurs?
They drilled in ice in Antarctica and studied the gas in the trapped bubbles
They used glass bubbles to gather air samples
They visited schools all over the world
They studied fossils
What does this graph tell us?
This graph tells us that the earth is in a cooling trend
This graph tells us that the CO2 in the atmosphere is falling right now
This graphs shows us that when the CO2 levels go up, the earth's temperature goes up.
This graph shows us the Keeling Curve
Which of these gasses in our atmosphere is NOT a greenhouse gas?
Oxygen
carbon dioxide (CO2)
methane
nitrous oxide

C
D
What causes coral bleaching?
oil spills
warmer water temperatures
overfishing

70 mm
50 mm
60 mm
30 mm
1.What does the picture represent?
Lines of latitude
Greenhouse effect
Climatic zones
Weather patterns
What is the main reason sea levels are rising rapidly?
melting sea ice
increase of water vapor in atmosphere
melting land ice
increase in floods
The reason we have seasons on our planet is because...
we are closer to the sun during the winter and further during the winter.
the tilt of Earth's axis allows for more direct sunlight in the summer and less direct sunlight in the winter.
seasonal wind patterns carry warmer winds during the summer and colder winds during the winter.
the Earth's orbit becomes more like an oval to give us different seasons.
What can scientists use to study how Earth's climate and atmosphere have changed over time?
Ice cores
Index fossils
Law of Superposition
Radioactive dating
Which is the best reason for scientists to study ice cores obtained from Earth’s ice caps?
to evaluate potential oil drilling sites
to study the quality of water stored in glaciers
to determine the rate of melting in polar regions
to study past climates by analyzing trapped gases and particles
