The hydrological cycle is a conceptual model that describes the storage and movement of water between the biosphere, atmosphere, lithosphere, and the hydrosphere.
The water we use today has been around for hundreds of millions of years, and the amount available probably hasn't changed very much.

Water is the source of all life on earth.
The distribution of water, however, is quite varied; many locations
have plenty of it while others have very little. Water exists
on earth as a solid (ice), liquid or gas (water vapor). Oceans,
rivers, clouds, and rain, all of which contain water, are in
a frequent state of change (surface water evaporates, cloud water
precipitates, rainfall infiltrates the ground, etc.). However,
the total amount of the earth's water does not change. The circulation
and conservation of earth's water is called the "hydrologic
cycle". The Hydrologic Cycle module has been organized into
the following sections:
The Earth's Water Budget ....The distribution of water
among the oceans, land and atmosphere.
Evaporation ....The transformation of water from a liquid
into a gas, a process which humidifies the atmosphere.
Condensation ....The transformation of water from a gas
into a liquid, and the processes that lead to condensation.
Transport ....The movement of water through the atmosphere.
Precipitation ....The transfer of water from the atmosphere
to land. Rain, snow, hail, sleet, and freezing rain are discussed.
Groundwater ....Water located below ground and how it
returns to the surface.
Transpiration ....Transfer of water to the atmosphere
by plants and vegetation.
Runoff ....Rivers, lakes, and streams transport water
from land to the oceans. Too much rainfall can cause excess runoff,
or flooding.
Summary and Example ....A brief encapsulation of the hydrologic
cycle, plus an example of the hydrologic cycle at work.

Welcome to VirtualRiver. Here you will find two interactive exercises designed to help you learn about river processes like discharge, flooding, and flood frequency. Each activity requires you to make careful observations and measurements, do simple calculations, and answer questions about your work.
RIVER FLOODING- This is a series of interactive exercises designed to help you learn about river processes such as discharge, flooding, flood frequency, erosion, and deposition.
Features
produced by running water
These terms form a good vocabulary you should be able to use and understand when sitting the examination.

The Severn Bore is one of Britain's few truly spectacular natural phenomena.
