Define Revolution
A complete of earth around the sun
Define erosion

What is the water cycle? (define each of the parts)
Water cycle
The process in which water is used and reused on Earth, including precipitation collection, evaporation, and condensation
Evaporation
The change of liquid water to water vapor
Condensation
The result of water vapor changing into a liquid or solid state
Precipitation
The water that falls on the ground as rain, snow, sleet, hail, or mist
How are tectonic plates and earthquakes related?
Define weathering
The process by which the Earth's surface is worn away by natural forces.
weather is the state of the atmosphere at a place and time while the climate is the average weather over a long period of time.
What is a bay and how does it compare to gulfs
