Sink

100

What are the two types of pure substances

Elements and Compounds

100

What is the supportive force that keeps us from falling?

normal force

100

What is the difference between energy transfer and transformation?

Transfer moves the same type of energy. Transformation changes the type of energy.

Noncontact: Gravity, Magnetism

400

What is the law of conservation of energy?

Energy cannot be created or destroyed, only transferred and transformed.

400

What is the difference between intrusive and extrusive igneous rock?

intrusive cools under earth's surface and extrusive cools above earth's surface.
