•
The total amount of water on the earth is about 326 million trillion gallons
(326,000,000,000,000,000,000). That would fill 410 trillion
Olympic size swimming pools.
•
Water is essential to our planet's life and without it nothing could survive.
The globe is two-thirds covered by water, but 93% is ocean water, toxic to
humans, plants and animals. There is the same amount of water on earth now
as there was when dinosaurs hung out at the local pond millions of years ago.
The water keeps moving in a cycle; it evaporates from rivers, lakes, and
oceans. The vapor from evaporation and condensation forms the clouds in the
sky and then returns to earth as rain, snow, sleet, or hail.
• The Earth's water supply is made up of: 97% oceans, 2% Icecaps/Glaciers,
1% Fresh Ground Water.
•
The best part about The Water Cycle is that you can start at any stage
because it is always circling around.
Understanding of the Water Cycle
• Evaporation- The sun heats water in rivers, lakes, and the ocean
and turns it into vapor or steam, which then rises into the air. There
is also transpiration (expulsion of excess water from plants) that
happens during evaporation. Example: A puddle full after rain, then
missing the next day.
Condensation- The vapor cools and turns into tiny water droplets
that attach to each other and form clouds. Example- When a cold
canned drink is introduced to more heat.
•
Precipitation- Water falls from the clouds as rain, snow, sleet, or hail.
Example-Rain
Then the cycle begins again, as water from the earth’s surface
evaporates into the air. But some one the water stays on the earth’s
surface and flows into rivers, lakes reservoirs.
• Carbon is a key ingredient of living tissue. Carbon and oxygen form
carbon dioxide gas, an important component of the atmosphere.
• Carbon dioxide is also taking in by plants during photosynthesis and
is given off by both plants and animals during respiration.
• Carbon is released through humans, respiration, volcanic activity,
and fossil fuels.
First- The Biological Process
Such as photosynthesis, respiration and decomposition, take up and release
carbon and oxygen.
Second- Geochemical process
Such as erosion and volcanic activity, releases carbon dioxide to the
atmosphere and oceans.
Third- Mixed biogeochemical Processes
Such as the burial and decomposition of dead organisms and their conversion
under pressure into coal and petroleum (fossil fuels), store carbon underground.
Fourth- Human Activities
Such as mining, cutting and burning forests, and burning fossil fuels, release
carbon dioxide into the atmosphere.
Nitrogen is odorless, tasteless, and colorless.
Nitrogen gas (N2) makes up 78.1% of the volume of the Earth’s air.
Nitrogen is a nonmetal.
Nitrogen gas is relatively inert, but soil bacteria can 'fix' nitrogen into a form that
plant s and animals can use to make amino acids and proteins.
Nitrogen compounds are found in foods, fertilizers, poisons, and explosives.
Nitrogen is responsible for the orange-red, blue-green, blue-violet, and deep
violet colors of the aurora.
