fed by rain. The flow of water varies a lot
from season to season.
- Glaciers are formed from the accumulation
of snow on mountain tops or covering
large areas on Poles.
- Lakes and pools are permanent bodies
of water deposited in depressions.
- Wetlands, marshlands and swamps are areas
where the ground is inundated all year round.
- Groundwater is water located beneath
the ground surface.
