Spheres of the Earth
The sphere made up of water.
The Hydrosphere.
What is it called when rocks get broken into smaller pieces by water, wind, and ice?
Weathering
Give two examples of fossil fuels.
Possible answers: Coal, Oil, or Natural Gas
Coal
Non-Renewable.
The Earth's sphere that is made up of air.
The Atmosphere.
Erosion
What type of rocks are used to heat our homes?
Sedimentary Rock (they have fossil fuels in them)
Renewable or Non-Renewable?
Solar Energy
Renewable.
The Earth's sphere that is made up of land and rocks.
The Geosphere.
What is it called when a river slows down and small rock pieces are dropped off?
Deposition
What type of gas is produced when fossil fuels are burnt?
Carbon Dioxide
Renewable or Non-Renewable?
Geothermal Energy
Renewable
The Earth's sphere that is made up of life.
The Biosphere.
What is the difference between compaction and cementation?
Compaction is when more and more layers are formed and pressed together.
Cementation is when salt, or minerals in the water, go into the spaces between sediments and "glue" them together.
What is one way that farming impacts the gasses in our atmosphere?
Possible Answers:
Clearing land = Less trees and more carbon dioxide
Burning fossil fuels = more carbon dioxide
Burping cows = more methane
What does it mean if an energy source is non-renewable?
Describe how (at least) three spheres would be affected if a volcano erupted.
Each sphere is connected and is affected by the others. A change in one sphere will affect all the other spheres.
After many layers of sediment have formed, what 3 things are required in order for them to become sedimentary rock?
Time, heat, and pressure
How does the burning of fossil fuels affect the Earth's temperature?
Gasses like methane and carbon dioxide trap heat in the atmosphere, making the Earth warmer.
What does it mean if an energy source is renewable?
Renewable sources are sources that do not run out.
