The repeated movement of water between earth’s surface and the atmosphere is a. the water cycle b. the condensation cycle c. precipitation d. evaporation

Water cycle is a natural cycle of water from the earth's surface to the atmosphere back to the surface again and infinity. During evaporation, the water on the surface of Earth is converted to vapor that goes to the atmosphere. During condensation, the vapor goes back to the surface of the Earth

Geothermic gradient is the rate of increasing temperature with respect to increasing the depth in the earths interior. away from tech tonic plates boundaries, it is about 25-40 c/km (72-87 degrees f/mi) of depth near the surface in most of the world.
