Evaporation occurs when molecules of a liquid (such as water) leave the liquid and become suspended in the air. Liquids are constantly losing molecules to the air at all temperatures, and some may be returned to the liquid from the air as they lose energy. However, the addition of heat energy can increase the rate of evaporation by exciting more of the molecules in the liquid.
At what is known as the "boiling point", most or all of the molecules will have enough energy to leave the liquid. If the air above has the capacity to absorb it, the liquid's molecules will eventually all be held in the air. If the air cools, reducing the energy of the molecules and the air's ability to hold them, the molecules may return to a liquid state, in the process called condensation.

What causes water to evaporate during the water cycle?
The principal cause is the kinetic energy of water molecules situated at the surface.
Which of the following evaporate in the water cycle?
Water from oceans, lakes, rivers, and streams evaporate as part of the water cycle.
What part of the water cycle does solar radiation affect directly?
The sun (and wind) causes sea water to evaporate and rise to form clouds.
What is the driving force of the water cycle?
Ultimately - the Sun... The heat from the sun causes water to evaporate. This forms clouds - which create rain. The rain falls to earth and is eventually evaporated by the Sun... The cycle continues !
What does energy that powers the water cycle comes from?
The energy that powers the water cycle comes from the sun. Solar energy causes water to evaporate from the Earth's surface, forming clouds and eventually leading to precipitation like rain or snow.
How the energy from the sun causes the water cycle?
cause water evaporate
What causes water to evaporate during the water cycle?

Which of the following evaporate in the water cycle?
Water from oceans, lakes, rivers, and streams evaporate as part of the water cycle.
What causes sea water to evaporate?
The heat from the sun causes sea water to evaporate
What causes water to evaporate and why is evaporation important in the water cycle?
Increasing the kinetic energy of water molecules located at the water surface favors evaporation.
What part of the water cycle does Solar radiation affect?
The sun (and wind) causes sea water to evaporate and rise to form clouds.
What part of the water cycle does solar radiation affect directly?
The sun (and wind) causes sea water to evaporate and rise to form clouds.
When energy from the sun warms the water on earth it causes water to do what?
The warming of water causes the water to evaporate which contributes water vapour to the water cycle and ultimately precipitation. Water vapour is also greenhouse gas. If the water is discharged into cooler water it causes thermal currents.
Why is the sun is the most important part of the water cycle?
It is heat from the sun that causes water to evaporate. Without the sun all water on Earth would freeze.
What is the source of enegry in the water cycle?
The source of energy that causes the water cycle to happen is the sun. Without the sun water would not evaporate and then it would not condense. If there is no water condensed into clouds then there wouldn't be any rain or precipitation.
What is the role of the ocean in the water cycle?
to evaporate
What is the driving force of the water cycle?
Ultimately - the Sun... The heat from the sun causes water to evaporate. This forms clouds - which create rain. The rain falls to earth and is eventually evaporated by the Sun... The cycle continues !
