In KS2 geography children will look at the water cycle - evaporation, condensation, precipitation, rivers and seas. Also covered in this topic is the treatment of sewage, drought and flooding.
The liquid that forms seas and lakes is water. Water is lifted from the surface of the Earth by evaporation. It then cools and through condensation forms clouds. These clouds when cooled further release their water as rain, sleet, hail or snow. It then falls back down to Earth and finds its way back to the sea through rivers. This process is called the water cycle. Water is essential to life and without it all animals and plants would die. Seas are made up of saltwater, whereas rivers are mostly freshwater. Water can be solid (ice), liquid (the sea) and gaseous (steam from a boiling kettle). Pure water is tasteless and odourless.
This quiz tests what you know about the water cycle - from evaporation, through condensation and rainfall and then back to the seas and oceans.

Water rises as vapour from the sea and the ground and forms as clouds. It then falls again as rain

Sunshine and wind can both cause evaporation. That's how wet clothes dry on a washing line - the sun and wind evaporate the water in them

When water vapour cools it forms droplets. The mist formed if you breathe on a mirror or window is condensation
