Module 1
Energy the Earth receives from the sun
Solar energy
What are the 3 states/forms of water?
solid, liquid, gas
The rain is causing soil to wash away from my garden and into the street.
Erosion
When water droplets become too heavy and fall down to earth in the form of rain, sleet, snow, or hail
precipitation
How long does one rotation of the earth take?
24 hours
The imaginary rod running through the North Pole to the South Pole which the Earth spins around
axis
Water vapor
The type of weathering where the color and type of rock stay the same, even though the rock may change size and shape.
Physical weathering
Water that soaks into the ground after it lands on earth's surface.
groundwater
What happens when tectonic plates slide?
earthquake
How long does it take the earth to travel around the sun?
Give two examples of water in it's solid form?
ice, snow, hail
Lime water drips into a cave and forms giant stalagmites.
deposition
The heating of water by the sun (changing water from liquid to gas)
evaporation
What tectonic plate movement causes underwater mountain ranges and even islands in the ocean?
separate
One complete spin of the Earth on its axis
Rotation
What percentage of the earth is covered salt water?
97 percent
The type of weathering where the rock changes from one type to another type. It may dissolve or change color as it breaks down.
Chemical Weathering
The evaporation of water from plants
transpiration
What part of the water cycle is when hot water vapor cools and changes back into a liquid (often forming clouds).
condensation
What is another word for revolution (the path the earth takes around the sun)?
orbit
What percentage of the earth is surface fresh water?
Less than 1%
What two word phrase do we say to remember the process of erosion?
Takes It!
Precipitation that overflows from the land into lakes, rivers, streams or the ocean.
Runoff
What are the three ways tectonic plates move?
collide, separate, slide
