Question

all day and all night evaporation constantly continue at a constant rate. true?

Answer 1

For the water cycle to work, water has to get from the Earth's surface back up into the skies so it can rain back down and ruin your parade or water your crops or yard. It is the invisible process of evaporation that changes liquid and frozen water into water-vapor gas, which then floats up into the skies to become clouds.

Note: This section of the Water Science School discusses the Earth's "natural" water cycle without human interference.

Answer 2

False

Becoz in night there is no sun so, constant rate of evaporation will be decreased in night and increase in day.
