What source of water is found below Earth's surface that fills spaces between rocks and soil?
What is groundwater.
100
Define erosion.
What is a process by which the surface of the Earth gets worn down or the materials get taken away by wind or water
100
Why is Earth often called the "blue planet?"
What is because water covers 3/4 of Earth.
100
List the four processes of the water cycle.
What is condensation, precipitation, collection/runoff, and evaporation.
100
Define weathering.
What is a process that breaks down rocks into smaller pieces.
200
Is most of the water on Earth's surface fresh water or salt water?
What is salt water.
200
Name a place in Arizona where erosion has occurred.
What is the Grand Canyon.
200
Where is most of Earth's fresh water found?
What is locked up in glacier and ice caps in the north and south poles.
200
List at least three places where water collects on Earth.
What is lakes, rivers, oceans, glaciers, streams, etc.
200
True or False. Can wind change the appearance of mountains? Describe why or why not.
What is true. The wind causes weathering and erosion and can make the mountains smaller and rounder.
300
Name two places where we find fresh water on Earth's surface.
What is swamps, rivers, lakes, streams, etc.
300
True or False. Can wind cause erosion? Describe why or why not.
What is true. Wind can cause erosion by moving or carrying away sediments from one place to another.
300
What percentage of Earth's water is salt water?
What is 97%.
300
List three different forms of precipitation.
What is rain, snow, hail, sleet, drizzle.
300
True or False. Weathering and erosion happen very quickly.
What is false. It takes many years for them to occur.
400
Name one difference between lake water and ocean water?
What is ocean water has salt water and lake water contains fresh water.
400
Describe how rivers cause erosion overtime.
What is carry sediments downstream.
400
What percent of the Earth is covered by water?
What is nearly 75%.
400
Describe what is happening during the process of evaporation.
What is the sun heats the water on Earth and turns it into water vapor, the water vapor rises into the atmosphere.
400
True or False. Can plants also cause physical weathering?
What is true. Their roots grow inside cracks in rocks, making the cracks bigger.
500
Describe what water vapor is.
What is when the sun changes water on the Earth's surface from a liquid to a gas. It rises from the surfaces of land, oceans, rivers, and lakes and enters the atmosphere.
500
Describe how oceans cause erosion.
What is the water in the oceans wash the sand away from the beaches.
500
What is the name of the process where water is continually moving from the atmosphere to the surface of the Earth and back again?
What is the water cycle.
500
Describe condensation.
What is when water vapor cools as it rises and turns back into a liquid.
500
How is physical weathering different from chemical weathering?
What is chemical weathering changes the chemical make-up of the rock and physical weathering does not. Physical weathering just changes in appearance. (answers may vary)
