WATER BERTWEEB SKY AND LAND!!

The sun heating makes the fusion of snow and ice.

When water evaporates it becomes visible only under ice shape like smallp drops.

The clouds are small droops of water and ice.

RAIN is a fall of small drops of water.

FUSION EVAPORATION AND CONDENSATION ARE THE THREE FASES OF THE WATER CICLE.

1) Water with hot temperature evaporates and goes up to the sky.

2) In the sky the small drops becomes bigger and together form the clouds.

3) When million of drops go together they become heavy and go down,if they meet warm air they form rain if don’t meet it they form snow or ice.

The qualities of water:

1)CAPILLARITY2) SUPERFICIAL TENSION3) DENSITY4) MELTING POWER5)TERMIC QUALITY

CAPILLARITY

IS THE ABILITY OF WATER lìand its solution to go up thin tubes.the tubes are called capillarity because they are like hairs.

SUPERFICIAL TENSION

They are due to the coesion quality, that is very important for water

DENSITY

In the main part of substances the solid state is more dense than liquid state. Water at solid state is less than water at liquid state.

MELTING POWERWater can melt many substances.Sea water is a liquid substance THE melting substance is the solvent

TERMIC QAULITY

Water can share great amount of heating with a very light change in its temperature.

It is a big mass of water that is in a close basin.

RiversRivers are water flows, where water flows all year.

Oceans They are a huge extension of water that separates continents

Sea Sea are smaller than oceans, less deep and less big.

Water use

Waste water
