The Earth's axis is an imaginary line that runs
between the South and North poles. As it revolves
around the Sun, the Earth spins or rotates on itís
axis. The period of one complete rotation is referred
to as a day and takes 23 hr 56 min 4.1 sec. The
period of one revolution around the Sun is referred
to as year, or 365.2422 solar days, or 365 days
5 hr 48 min 46 sec.
What is the Atmosphere?
- The Earth is wrapped in a thin blanket of air,
which extends upward from the surface slowly
thinning out into space. These
are called the atmosphere.
the Green House Effect?
- The greenhouse effect is naturally occurring and
essential to Earthís climate. The sunís energy enters the
atmosphere in the form of light waves and heats up the
Earth. After warming the Earth this energy bounces off
the surface in the form of infrared waves. The gases in the
atmosphere naturally trap a portion of these outgoing infrared
rays while others travel through the atmosphere into outer
space. For thousands of years the Earth and the Sun have been
in perfect Balance creating an average temperature on Earth
of 59 degrees Fahrenheit (15 degrees Celsius). Without our
greenhouses gasses our average temperature would be about
0 degrees Fahrenheit (or minus 18 degrees Celsius).
Q-What is Global Warming?
- Carbon dioxide caused by human activity and other
greenhouse gases have added AND continue to add to the
Earthís atmosphere making it thicker. In this thicker state
the atmosphere traps a lot of the infrared radiation. It is
no longer able to easily escape the atmosphere and continue
into outer space. As a result, the temperature on the Earth
is getting warmer,
hence the name Global Warming.
Q- So Why Does That Matter?
One result of Global Warming is climate change or
As the oceans get warmer storms get stronger. The Earth may
more hurricanes, typhoons, cyclones and tornadoes. People will notice
unseasonably cold or
warm weather. This may include droughts, fires or flooding. As the climate
plants and animals could become extinct.
