Shark teeth were discovered in an area where there was no source of water. What is the BEST explanation for this?
Sharks used to live on flat land.
The area was once covered with salt water.
The area was once covered with freshwater.
Someone buried the shark teeth deep in the ground.
Tree fossils were found in the desert. What can we infer about the tress and the land where the fossils were found?
Trees adapted to live in the desert.
The tress are extinct now, but used to live in the desert.
This area has many trees because it has always been a desert.
The area was once home to many trees and has not always been a desert.

What makes something a nonrenewable resource?
it is a resource that can be easily replaced.
it is a resource that cannot be replenished or replaced in a short period of time.
it is a resource that is abundant in nature.
What makes something a renewable resource?
it can be replenished at the rate that it is being used
it takes years to be replenished
it has to contain water
What are fossil fuels?

made up of living plants and animals.
What is one disadvantage of using fossil fuels?
They do not produce much heat.
They are difficult to use.
They are nonrenewable resources.
They produce more water than other fuels.
What is the primary benefit of solar power plants compared to many traditional power plants?
They can operate at night.
They produce electricity by burning fuel.
They help reduce the amount of carbon dioxide in the atmosphere.
They require less engineering.
Why do power plants contribute to carbon dioxide emissions?
They use solar energy which emits carbon dioxide

They capture carbon dioxide from the atmosphere
The graph shows changes in carbon dioxide
(CO2) concentrations and surface temperatures
on Earth from the years 1880 to 2000.
Why do carbon dioxide concentrations and
surface temperatures show the relationship seen
in the graph?
because lower carbon dioxide levels mean more heat is retained in Earth's atmosphere
because higher carbon dioxide levels mean more heat is retained in Earth's atmosphere
because lower carbon dioxide levels mean less heat is retained in Earth's atmosphere
because higher carbon dioxide levels mean less heat is retained in Earth's atmosphere
Which human activity would help reduce the amount of carbon dioxide in the atmosphere?
increase the number of cars being driven
decrease the number of recycling programs
decrease the burning of fossil fuels
increase the human population
What is the primary gas responsible for the greenhouse effect?
Oxygen
Carbon Dioxide
Nitrogen
Hydrogen
Explain how the greenhouse effect contributes to global warming.
The greenhouse effect traps heat in the atmosphere, leading to an increase in Earth's temperature.
The greenhouse effect releases heat into space, cooling the Earth.
The greenhouse effect blocks sunlight, reducing Earth's temperature.
The greenhouse effect has no impact on Earth's temperature.

False
True
The concentration of greenhouse gasses will likely decrease in the future.
False
True
How can Global Warming cause sea levels to rise?
by causing it to rain more often.
by creating bigger and more powerful hurricanes.
by melting glaciers and ice caps.
