How does heat affect matter?
When heat is added, energy is added to matter, causing the atoms to move around faster.

What is a trough?
A trough is a long depression or hollow between two waves.

What causes earthquakes?
Earthquakes are caused by tension and pressure from moving plates, finally shifting and cracking, causing the earth to shake.

What is a mechanical wave?
A wave that transfers energy through a medium.

How are atoms different in gases, liquids, and solids?
Gases- Atoms are spread out and move freely. Liquids- Atoms are close together and they slide around. Solids- Atoms are packed closely together. They bond and do not change shape.

How are divergent boundaries different from convergent boundaries?
In divergent boundaries crustal plates move away from each other and in convergent boundaries, crustal plates collide with each other.

Physical changes are usually reversible changes in the physical properties of given substances. Give an example of a physical change.
Answers will vary.

How are transverse waves different from longitudinal waves?
In transverse waves particles vibrate at right angles to the direction of the wave and in longitudinal waves, particles vibrate back and forth in the same direction as the wave is moving.
