Which process mostly takes place over oceans?

• A. Evaporation
• B. Condensation
• C. Precipitation
• D. Transpiration

Answer: (A)

Evaporation is the process by which liquid water becomes water vapor. It happens when heat from the sun warms water on the surface, giving water molecules enough energy to break free into the air. Oceans provide by far the largest surface area and the most liquid water, so they are the main source of water vapor entering the atmosphere. Once vapor is in the air, it can rise, cool, and condense to form clouds, which may lead to precipitation elsewhere. Transpiration relies on plants and mainly occurs on land, while condensation is the cooling of vapor into liquid in the atmosphere. Precipitation is the return of water to Earth's surface, not the initial transfer of water from oceans to the air. So evaporation is the process that mostly takes place over oceans.
