The force of attraction that pulls objects toward the center of the Earth.
Gravity
The average kinetic energy in the particles of an object.
Temprature
The thinnest, outermost layer of the earth, where we live.
The crust
When two plates collide and one goes under the other
Convergent Plate Boundary.
a series of powerful ocean waves—not just one—caused by large-scale, underwater disturbances like earthquakes, landslides, or volcanic eruptions
Tsunami

Potential Energy
What is Thermal Energy?
the energy from the movement of tiny particles (atoms and molecules) inside things, making them warm
