The troposphere is the lowest layer of the atmosphere which starts
at the Earth's surface and extends from 5 to 9 miles. It is the
densest and the most weather is in this layer. The temperature
and pressure drop as you go higher in the troposphere.
What is in it: Humans,
landforms, living organisms,
man-made objects,
contraptions, buildings, etc.
Stratosphere
Ozone
A thin layer in the stratosphere which contains ozone that
absorbs and releases the sun's ultraviolet radiation.
The stratosphere is just above the troposphere and extends
to 31 miles high. It is warmer at the top than at the bottom.
What is in it: Balloons, planes,
jets
Mesosphere
The mesosphere is above the stratosphere and is 53 miles high.
This is where meteors burn up when they are in this layer.
What is in it: Airglow, polar
mesospheric clouds
Thermosphere
The thermosphere is above the mesosphere and is 372 miles high. The
temperature is so high that it may be in the thousands; however some of
the molecules in the thermosphere would feel very cold on our skin
What is in it: Auroras and
sattelites
Exosphere
The last layer of the atmosphere which is 6,200 miles high.
The Water-Cycle
1.)
Evaporation
When water is heated by
thermal energy, it turns
to water vapor or steam
which rise up to the air.
Transpiration
Transpiration is the
process when plants
release water from their
leaves, or basically
"plant sweat".
2.)
Condensation
The process when water
vapour cools in the air, turns
back to liquid, forming
clouds. —Or basically water
vapour forming clouds.
3.)
Precipitation
Precipitation happens when enough water
has made a cloud heavy that it can't hold it
anymore; so, the water falls back to Earth.
—Or, you can just call it rain or snow
REPEAT
After precipitation(raining), the process
keeps repeating forever.
How can solar energy
impact the water
cycle?
Solar energy is one of
the main sources of
running the water
cycle; it evaporates
water and helps plants
grow.
What are the effects of
certain human activity
on climate?
Deforestation
Deforestation is the act of cutting
down trees for space or for creating
products.
It can harm the climate because
deforestation can reduce trees
which mean less transpiration
