Uniform

4. Atmospheric Layers
Earth’s atmosphere is the layer of gases that surrounds the planet and makes conditions on Earth suitable for living things.
Earth’s atmosphere is divided into several different atmospheric layers extending from Earth’s surface outward:
Troposphere
Stratosphere
Mesosphere
Thermosphere
Ionosphere
Exosphere
The Steaks Must Thaw In Europe!
MENU

5. Atmospheric Layers
The layer of gases surrounding Earth; composed mainly of nitrogen and oxygen
MENU

6. Troposphere Atmospheric Layers
This is where all plants and animals live and breathe
Where weather takes place
Air is mixes
T decreases with altitude
MENU

7. Stratosphere Atmospheric Layers
Ozone in this layer stops many of the sun's harmful rays from reaching the earth
People can not breathe in this layer.
Ozone layer depletion over time
MENU

8. Mesosphere Atmospheric Layers T decreases with altitude
This is where we see "falling stars" – meteors burning up as they fall to Earth
MENU

9. Thermosphere Atmospheric Layers
Layer of the atmosphere which is first exposed to the Sun's radiation and so is first heated by the Sun.
The air is very thin
The temperature dependent on solar activity.
MENU

10. Ionosphere Atmospheric Layers
An extension or a part of the thermosphere. So technically, the ionosphere is not another atmospheric layer.
Free electrons
and ions tend
to recombine
MENU

11. Atmospheric Layers Animation
Exosphere
Highest layer of the atmosphere. The air is very thin here
Atoms and molecules escape into space

14. Tuesday 8-21-18 Q.O.D. This is the first layer of the atmosphere
to be heated by the sun. Identify this
layer.
--Answer
Thermosphere

15. Atmospheric Gases Nitrogen and Oxygen
· the two most common gases; found throughout all the layers
Ozone
· a form of oxygen found in the stratosphere
Water vapor and
Carbon dioxide
· important gases for weather conditions; found in the
troposphere
Trace gases, argon
· play an insignificant role
MENU

16. Atmospheric Gases Ozone Layer Pale blue gas with a strong odor.
90% of all ozone is found in the stratosphere
10% is found in the troposphere
Ozone is extremely important because it is the only gas that absorbs ultraviolet radiation from the Sun and protects the surface of the Earth and people from the damaging effects of UV rays
MENU

17. Atmospheric Temperatures
Differences in temperature
separate the layers
· As altitude increases, temperature decreases in the troposphere
· The stratosphere is cold except in its upper region where ozone is located
· The mesosphere is the coldest layer
· Even though the air is thin in the thermosphere, it is very hot
· The cold regions of outer space extend from the exosphere
MENU

18. Atmospheric Pressures
The air pressure, the force exerted by the gases pushing on an object, is greatest near the surface of Earth, in the troposphere.
· Air pressure decreases through the layers farther out from the surface as Earth’s pull of gravity decreases.
Troposphere pressure
Decreases
Exosphere
Troposphere pressure

19. Atmospheric pressure decreases as the altitude increases.

24. Water Cycle
includes precipitation, evaporation, transpiration, condensation, surface-water flow, and groundwater flow
Water is always moving between the atmosphere (troposphere) and surface of Earth.
Each components of the water cycle process has certain conditions under which each form of precipitation develops:
MENU

25. MENU

26. Water Cycle Precipitation
· After condensation occurs (forming clouds), water droplets fall in various forms of precipitation – rain, snow, freezing rain, sleet, or hail, depending upon weather conditions.
· Temperature variations within clouds and/or within the region between the cloud and Earth allows for the various forms of precipitation.
MENU

27. Precipitation Rain & Drizzle- most common type of precipitation.
Freezing Rain- drizzle from stratus clouds.
Freezing Rain- raindrops freeze when they hit the ground.
Sleet- raindrops that freeze before they hit the ground.
MENU

28. Precipitation
Sleet Profile

29. Precipitation
snow- as ice grows and merges into clouds they form snowflakes.
hail- is the largest type of precipitation.
Lumps or balls of ice that fall from cumulonimbus clouds in warm weather.
MENU

30. MENU

31. Evaporation/Transpiration
Water Cycle
Evaporation/Transpiration
· Water enters the atmosphere as water vapor through evaporation and transpiration, plants releasing water vapor.
Humidity- the amount of water vapor in the air
Relative humidity- compares the amount of water in the air with the maximum amount of water vapor that can be present at that temperature
MENU

32. Water Cycle · Condensation happens in the atmosphere as water vapor
changes to water droplets.
· Clouds form as a result of
condensation.
· Dew forms when water vapor condenses directly onto a surface;
· Frost forms when water vapor changes from gas directly to ice crystals on a surface when the temperature at which condensing would take place is at the freezing point or below.
MENU

33. Groundwater Story Animation
Water Cycle
Run-off
· If precipitation falls on land surfaces, it always attempts to move back toward sea level as surface-water flow or groundwater flow.
· The surface that receives the precipitation determines its flow back towards sea level.
MENU
Groundwater Story Animation

34. Examples are:
· Water will remain on the surface when the surface is not porous or the precipitation is falling too fast for the water to sink into the ground.
· Water will sink into the ground when the surface is porous and there is lots of space in the soil to hold the water.
