describe the forms that water takes throughout the water cycle
liquid, vapor, clouds, precipitation, and surface runoff
how do internal and external forces of change affect earth's surface differently
internal forces of change cause a rising of landforms and can be dramatic and sudden. external forces of change usually wear away landforms and are usually slow
