Science III - EARTH'S WATER SUPPLY

[blank_start]Water[blank_end] is alo know as Universal Solvent

[blank_start]Water[blank_end] is called [blank_start]Universal Solvent[blank_end] because it dissolve more substances than any other liquid

Water covers up [blank_start]70%[blank_end] of the surface of the earth

[blank_start]97%[blank_end] is salty water

[blank_start]3%[blank_end] is freshwater

[blank_start]Ocean[blank_end] is a very large expanse of sea

[blank_start]River[blank_end] is a natural flowing watercoarse, usually freshwater, flowing towards an ocean, sea, lake, or another river

[blank_start]Rain[blank_end] is a liquid water form in a droplet

[blank_start]Water well[blank_end] is an excavation of structure created in the ground

[blank_start]Spring[blank_end] is stored underground water, which seeps from an opening in the ground

[blank_start]Pond[blank_end] is a small body of water either natural or artificial that is naturally smaller than a lake

[blank_start]Tap well[blank_end] is the water drawn off throuh taps of wires in a house

Water exists in three states: [blank_start]Solid[blank_end] - polar icecaps, glaciers, icebergs [blank_start]Gas[blank_end] - in the atmosphere [blank_start]Liquid[blank_end] - oceans, seas, rivers lakes

The waters of the earth [blank_start]constantly change[blank_end] from one state to another as it goes around in a cycle

[blank_start]Evaporation[blank_end] - when water from oceans, seas, and lakes change into water vapour due to the heat of the sun

[blank_start]Transpiration[blank_end] - when water vapour is released from the leaves of plants also due to the heat of the sun

[blank_start]Condensation[blank_end] - when water vapour turns into liquid form of tiny droplets high up in the cool portion of the atmosphere, forming clouds

[blank_start]Precipitation[blank_end] - when clouds get heavy with too much water droplets that the cloud could no longer hold together

[blank_start]Collection[blank_end] - when water falls back to Earth as precipitation it may fall back in the oceans lakes or Rivers or it may end up on land

[blank_start]Melting[blank_end] - when ice and snow change into liquid form due to heat from the Sun They flow into [blank_start]Lake[blank_end] [blank_start]river[blank_end] and [blank_start]oceans[blank_end] as well

Water storage - [blank_start]artificial ponds[blank_end], [blank_start]tanks[blank_end], [blank_start]reservoir[blank_end] and [blank_start]dams[blank_end].

Water storage happens [blank_start]when[blank_end]: 1. The earth [blank_start]soaks[blank_end] up [blank_start]some[blank_end] of the [blank_start]water[blank_end] and [blank_start]temporarily[blank_end] stores it [blank_start]underground[blank_end] 2. [blank_start]Plants[blank_end] [blank_start]absorb[blank_end] and [blank_start]store[blank_end] [blank_start]water[blank_end]

[blank_start]Aquifer[blank_end] - storage of water underground [blank_start]Underground[blank_end] [blank_start]formation[blank_end] of [blank_start]Rock[blank_end] and [blank_start]soil[blank_end] [blank_start]Part[blank_end] of the [blank_start]Watershed[blank_end] phone [blank_start]underground[blank_end]
