The hydrologic, rock, and tectonic cycles are powered by two main energy sources. They are the Sun and interior of Earth (core). The hydrologic cycle is the natural sequence through which water continues moves and passes into the atmosphere as water vapor.It is also known as water cycle. The sun, provides the energy needed for evaporation like the flame for a gas stove gives the energy for water to boil water and make steam.
The answer is subduction zone, this describes the action of
having one slide and another plate beneath and merge into the mantle of the
earth. This usually happens when collision occurs such as having tectonic plates
collide of each planet.
