W S The Hydrosphere

I Underline the correct word from each pair in the statements about the water
cycle below:
1. Energy is absorbed/given off when water evaporates/condenses from
oceans and lakes.
2. This process has the effect of warming/cooling its surroundings.
3. Energy is absorbed/given off when water vapour evaporates/condenses into
clouds in the atmosphere.
4. This process warms/cools the surroundings.

Q IV HOTS question:
What role do large bodies of water play in the earth’s climate system and the
flow of thermal energy?
Large bodies  of  water  affect  climate  in  many  ways,  but  perhaps  the  most
significant impact is based on the fact that large bodies of water act as heat
sinks. In other words, large bodies of water tend to store heat in warm periods
and release it in cold periods. This is because the thermal capacity of water is
high, meaning it takes a lot of energy to change the temperature of water. So,
during the summer, land areas near a large body of water may not heat up as
much  as  areas  that  are  not  close  to  water,  because  the  water  itself  is
adsorbing  much  of  the  heat  energy.  This  will  cause  the  climate  to  be  more
moderate in summer near the coast, for example. Likewise in winter, the water
near the coast will slowly release this energy, causing coastal areas to be less
cold, in general, than inland areas
