Natural Science 7th grade (Training Test)

Water reserves of solid water are in form of

• clouds

• ice

• rain

• rocks

the reserves of solid water can be found in

• in rivers and lakes

• under the seas

• polar areas and the top of high mountains

• in the clouds

When the ice of mountains melts it goes on the earth surface as

• land

• oceans

• clouds

• rivers

Sometimes water accumulates in the surface without going to the oceans, in the form of:

• water vapor

• oceans and rivers

• lakes and lagoons

• snow and rain

when water ir absorbed from surface it is called

• groundwater

• pollution

• transformation

• evaporation

In the atmosphere we can find water in the form of

• groundwater

• water vapor and clouds

• lakes and lagoons

• rivers and seas

The most abundant reserve of water is in

• rain

• polar caps

• clouds

• oceans

Water of rivers oceans and lakes evaporate because of

• x-rays

• sun's rays

• the wind

• the water vapor

In condensation, water form

• clouds

• rain

• water vapor

When water evaporates from plants in the form of vapor it is called

• infiltration

• precipitation

• condensation

• Transpitation
