Decreases
400
The type of boundary that forms when plates slide past each other

Transform Boundary

Explain why you can see your reflection in a mirror.

light reflects off you, bounces off the mirror, and enters your eyes

500

Compare amplitude and frequency. What does each affect?

amplitude affects loudness and frequency affects pitch

500

Two north poles are pushing very close together. What will  happen and why?

They will strongly repel because the same poles repel and the closer they are together, the more force they will repel with.

A planet with greater mass has this type of gravitational force compared to a smaller object

A greater gravitational force
