this is a type of solar energy; it just uses heat from the sun to warm
What is passive solar energy
100
water gets down into the cracks and freezes, when it freezes the water expands into ice and breaks the rock apart
What is frost wedging
100
resources that can be replenished within a relatively short period of time
What is renewable resources
100
movement of chemicals through soil, usually washed down by water is:
What is leaching
100
breaking down rock by changing into a different substance
What is chemical weathering
200
material the erodes to form the soil is:
What is parent material
200
steam comes out of the ground and turns the turbines to make electricity
What is geothermal energy
200
moving particles are:
What is erosion
200
natural resource that is not made of minerals, trees, fossil fuels, sand and gravel, etc.
What is non-mineral resources
200
on top of the parent material; made a mixtures of sand, silt, and clay and gravel. below is bedrock
What is c horizon
300
what is the main agent to wear away rock
What is water

list one of two of the problems to building solar energy is:
What is cost and sun doesn't shine always
300
a concentration of naturally occurring material. it is not renewable
What is mineral resources
300
movement of water down through the soil is:
What is percolation
300
subsoil, has material leached through upper horizon; may have hard rock below it
What is b horizon
400

What is soil structure
400
waves turn the turbines and make electricity
What is wave power
400
uses water behind a dam and released through turbines to produce electricity
What is hydroelectric power
400
broken down rocks are:
What is mineral matter
400
produced by electrical generators (turbines turn generators)
What is electric energy

surface layer made up of decomposing plants (humus)
What is o horizon
500
transfer of rock and solid down slope due to gravity
What is mass movement
