When rain hits the ground it pools into puddles,
seeps through the ground, flows into streams,
travels through rivers and flows into lakes,
reservoirs and out into the sea (these water bodies
are collectively referred to as wetlands).
Throughout its journey through these wetlands the
rain water is absorbed, stored, slowed and filtered.
It is also used by wildlife and people to get around
in, have water fights, drink and wash.
Humans have altered the natural water cycle by
creating surfaces like roads and roofs that stop
water soaking into the ground and using pipes to
move the water around. These changes have had some
interesting (and not always good) results.
Complete the missions in this chapter to discover
how water gets from A to B and the effects it has in
between.
