Atmosphere
Review
- Layers of the atmosphere
- Troposphere
- 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
