Energy Resources
Materials on earth that are available for our use
natural resources
A resource that won't run out or that can be replenished faster than it is used
renewable resource
Metals that are soft or shapeable are characterized as this.
malleable
All of earth's water found in lakes, oceans, streams, rivers, soil, underground, and in the air is referred to as this
hydrosphere
An ice sheet is what type of frozen water?
Fresh
This is formed when the remains of plants and animals are buried quickly.
fossil fuels
Windmills use this or air movements to generate electrical energy, but can take up lots of land.
wind energy
This is the most abundant metal in the earth's crust.
aluminum
Water falls to the earth as what?
precipitation
Ice shelves that break off into the ocean and float independently
Icebergs
A resource that cannot be replaced easily and will eventually run out is called this.
nonrenewable resource
This type of energy uses water power to produce electricity.
hydroelectric energy
A method used by farmers in which they plow furrows horizontally around a hill instead of up and down it to help prevent erosion.
contour plowing
A small plant-like organism that plays a key role in the carbon dioxide/oxygen cycle.
Phytoplankton
Frozen ocean water
sea ice
A material that contains usable amounts of metal
Ore
Sunlight is used to power and heat
Solar Energy
A low-growing crop such as clover that prevents soil erosion when fields are lying fallow (resting)
ground cover
A layer of sand, gravel, or bedrock that holds and moves ground water.
aquifer
An ice sheet that continues to float on the water
Ice shelf
A concentrated area of a specific mineral
vein
Heat from the earth that produces steam. There is no consumption of the heat source
geothermal energy
Separating metal in ore from other materials
smelting
Evaporation from a plants leaves.
transpiration
This continent is covered by several large ice sheets
