3 Types of Water on Earth
3/4 of the Earth's surface is covered with water:
* 97% Salt Water
* 2% Frozen Water (Ice)
* 1% Fresh Water
3 states of matter
* Solid = Ice
* Liquid = liquid water (rain, drinking water)
* Gas = water vapor or steam
Freezing point of water
* 32 degrees Fahrenheit
* 0 degrees Celsius
Boiling point of water
* 212 degrees Fahrenheit
* 100 degrees Celsius
The sun's WARMTH causes the water from oceans, lakes, rivers, etc. to evaporate up into the atmosphere.
After the water evaporates, the TEMPERATURE FALLS and cools down. Water condenses into water droplets. These droplets form clouds (fog too).
If the water droplets in the clouds become too heavy, they fall to the Earth as rain, sleet, hail, or snow.
Water that falls back to the Earth collects back into oceans, lakes, and rivers.
This is the rainfall that is NOT absorbed by the soil. This water flows back to the ocean.
This is the rainfall that is absorbed into the soil.
This is the water that evaporates from plants
This is the amount of water vapor in the air.
The more humid the air, the more likely it is to rain.
H2O (2 Hydrogens and 1 Oxygen)
The Water Cycle
This is the process by which water moves through the Earth and atmosphere.
Rain, Sleet, Hail, or Snow
