Water moves from earth's surface to the atmosphere and back to earth's surface again in a process known as the water cycle. which of the following is the major form of energy driving the water cycle?
a. nuclear energy
b. geothermal energy
c. solar energy
d. chemical energy

One of the major forms of energy driving the water cycle is geothermal energy. Heat is responsible for warming up water, which in turn evaporates, and then again returns to Earth's surface in the form of rain. 

Solar energy drives the water cycle on Earth.

Answer: buoyancy forceexplanation: in simple terms, the principle states that the buoyancy force on an object is equal to the weight of the fluid displaced by the object, or the density of the fluid multiplied by the submerged volume times the gravitational acceleration, g. this is also known as upthrust.
