What is potential energy?
Building up of energy, released when kinetic energy exerts.
What are some nonrenewable resources?
Coal, Oil, Nuclear energy, Fossil fuels.
What is evaporation?
Gas to liquid.
What are igneous rocks?
Cooled down magma or lava, forming a type of rock.
How can rocks get weathered?
Chemicals or Mechanical energy.
What is kinetic energy?
The exertion of energy through movement.
What are some renewable resources?
Solar power, Wind energy, Water energy, Heat energy, Biomass.
What is condensation?
Liquid to gas.
What are sedimentary rocks?
Buildup of small rocks, compressed into one.
What is erosion?
The movement of sediments.
What is mechanical energy?
Either kinetic energy or potential energy.
What is a screw?
Anything taking a spiral form.
What are some forms of substances on earth?
Solid, liquid, and gas.
What are metamorphic rocks?
A rock already being heated, but heated to a new form.
What is gravity?

How hard is Diamond on the MOH's scale

What is mechanical weathering?
1. Root action - The roots of plants, or trees, push up out of the ground, or dig into the rock, breaking it.
2. Ice wedging - Water gets into the cracks of rocks. When the weather drops at night, the water turns into ice. Ice expands, The expansion of the ice turns a little crack into a big crack till it actually breaks the rock.
What is an axle?
The pin, bar or shaft by means of which a wheel or pair of wheel rotates
What is mass?
anything that has mass, similar to weight, and volume, taking up space
What is an atomic number?
It represents the number of protons in the nucleus of an atom
Talc
What are some examples of chemical weathering?
1. Oxidation - when oxygen atoms in the air mix with the atoms of the metallic rock, in other words, rusting.
2. Acid Rain - When pollution in the air mixes with water vapor in the air to form a mild acid which affects the rock
