The correct option is this: VARIATIONS ARE GREATER OVER LAND THAN OVER WATER.
Temperature variation over water is very small compared to temperature variation over land. This is because, water has high specific heat capacity, which enables it to resist temperature changes when it absorb heat or when it releases heat. A large amount of heat has to be lost or gained before water will show a one degree Celsius temperature change.
Transpiration: process in which plants release water vapor into the air
Evaporation: process in which water changes to a vapor
Precipitation: water that falls from clouds toward the ground
Condensation: water vapor that cools down to form water droplets
Groundwater: flowing of rainwater downhill to form streams and rivers
