Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What is the driving force of the water cycle?
A
evaporation from the ocean
B
heat from the sun
C
precipitation from rainfall
D
runoff from mountains
Explanation: 

Detailed explanation-1: -The water cycle is driven primarily by the energy from the sun. This solar energy drives the cycle by evaporating water from the oceans, lakes, rivers, and even the soil. Other water moves from plants to the atmosphere through the process of transpiration.

Detailed explanation-2: -Gravity causes precipitation to fall from clouds and water to flow downward on the land through watersheds. Energy from the sun and the force of gravity drive the continual cycling of water among these reservoirs.

Detailed explanation-3: -The water cycle is powered by heat energy from the Sun.

Detailed explanation-4: -The energy obtained by the sun is called solar energy. It is the driving force of the ecosystem.

Detailed explanation-5: -The water cycle consists of three major processes: evaporation, condensation, and precipitation. Evaporation is the process of a liquid’s surface changing to a gas. In the water cycle, liquid water (in the ocean, lakes, or rivers) evaporates and becomes water vapor.
