Changes to Land
What are some different forces that can change Earth’s surface?
Wind, water, or ice can change Earth’s surface.
What are fossil fuels?
Fossil fuels are formed over millions of years from the deposition of organic materials in layers.
Sand dunes are created when sand is moved and deposited by
strong, persistent winds
What are the three major fossil fuels?
The three major fossil fuels are coil, oil, natural gas.
Rivers create landforms as they move across the surface of the Earth. Rivers move as water flows from
high in the mountains, down to oceans and lakes
Explain why fossil fuels are nonrenewable resources.
Fossil fuels are nonrenewable resources because of the time it takes them to form.
Distinguish between rapid changes to the Earth’s surface and slow changes.
Rapid changes are caused by volcanoes, earthquakes, landslides, hurricanes, and tornadoes. The land can be dramatically different from one day to the next.
Wind, water, and ice make slow changes to the Earth that usually occur over an extended amount of time.
Predict what will happen as the world’s supply of fossil fuels declines.
The prices for fossil fuel products will increase. We would need to provide energy through alternative resources.
