Rain has shaped the planet that we inhabit. It has
carved through rocks, defined where animals can
survive, where plants can grow and influenced
where you live. As an explorer you can live for
weeks without eating a meal but you can only
survive a few days without water.
While many dry parts of the planet are dependent on
rivers to bring them life, rain clouds are the most
effective way of getting water around Earth. A
single cloud might produce 25,000,000,000,000
droplets or 25,000,000,000 litres of water. When
this water pours down on the land below it can
allow wildlife to drink, farmers to produce food
and you to wash. Unlike water pipes, canals and
trucks clouds are 100% free.
Knowing what rain is, why it forms and how to make
the most of it is important. Complete the missions
in this chapter to learn more about this vital
liquid.
