Igneous rocks form from

• large amounts of heat and pressure.

• magma that has cooled.

• sediments which become cemented together.

• land that has eroded.

Sedimentary rocks form from

• sediments that are cemented together.

• magma that has cooled.

• very large amounts of heat and pressure.

• physical weathering of rocks.

Metamorphic rocks form from

• erosion carries particles away.

• magma that has cooled.

• sediments that are cemented together.

• very large amounts of heat and pressure.

Other that color, what is another property to determine a type of mineral?

• size

• mass

• capacity

Which are resources that are renewable?

• wind, oil, fruits, and coal

• natural gasses, oil, water, and coal

• vegetables, wind, solar energy, and water

• tides, sunlight, wind, and oil

Why is solar energy a renewable resource?

• because it uses sunlight which can be stored.

• because it uses sunlight which can be used up.

• because it uses sunlight which is a natural resource.

• because it uses sunlight which helps people.

A renewable resources is one that

• will eventually run out.

• is replenished by the Earth.

• can be recreated in a laboratory.

• is found on other planets.

A nonrenewable resource is one that

• can be created by humans.

• is found only in the oceans.

• is being used faster than the Earth can replace it.

• is not part of the water cycle.
