The Earth’s Atmosphere re-teaching assignment

The Earth is surrounded by a “blanket” of air called the atmosphere. http: //www. lunaroutpost. com/gallery/earth/pages/earth_full_hires%20 copy. htm

The Earth’s Atmosphere is a mixture of gases: http: //webusers. astro. umn. edu/~john/Ast 1001/air/atmos-compos. jpg

What are some natural events that afffect the earth’s atmosphere? Forest fires Volcanic ash http: //upload. wikimedia. org/wikipedia/en/thumb/4/49/Wildfire 3. jp g/240 px-Wildfire 3. jpg http: //www. windows 2 universe. org/earth/interior/ash. html

What keeps the atmosphere so close to the earth? ? ? GRAVITY! http: //www. cs. dartmouth. edu/farid/sciencekids/gravity 2. jpg

Although it seems thin, the atmosphere is ~500 miles thick!

Even the International Space Station flies within the Earth’s atmosphere! http: //nssdc. gsfc. nasa. gov/image/spacecraft/iss. jpg

The atmosphere has five basic layers. http: //www. theozonehole. com/atmosphere. gif

THE LAYERS ARE DETERMINED BY CHANGES IN TEMPERATURE http: //www. windows 2 universe. org/earth/Atmosphere/layers_a ctivity_print. html

Temperatures in the Atmosphere Why does the graph zigzag back and forth?

We live in the lowest layer, the troposphere. http: //www. fas. org/irp/imint/docs/rst/Sect 14/atmosphere. jpg

Most of Earth’s weather takes place in the troposphere. http: //images. worldofstock. com/slides/TRA 1094. jpg

About ten miles up is the Tropopause, where the troposphere ends. Most jet planes can fly close to or just above the tropopause.

Between each atmospheric layer, we have a “pause” or break. These arbitrary lines- and not real breaks. http: //www. epa. gov/apti/course 422/images/fig-1. gif

After the troposphere comes the stratosphere. http: //www. greenfacts. org/glossary/images/stratosphere-troposphere. jpg

High winds in the statosphere are called the Jet Stream. www. accuweather. com/www/nyc/jetstream. gif

The Ozone layer (O 3) can be found in the stratosphere. It protects us from harmful UV radiation from the sun. http: //veimages. gsfc. nasa. gov/138/ozone_hole_large. jpg http: //www. okiu. ac. jp/Language/contest/02/12/ozone. gif

Weather Balloons explore the stratosphere. http: //www. ssec. wisc. edu/sose/wvi/images/scen 3. jpg http: //www. discover. uottawa. ca/~aelsawah/GNG 1101/LAB 2_files/image 004. jpg

In the Stratosphere… spy planes! http: //retrothing. typepad. com/photos/uncategorized/2007/12/21/sr 71 bla ckbird. jpg

Believe it or not, 99% of all the gases that surround the earth are found in the first two layers we’ve seen so far.

Mesosphere is the layer In the Middle!

Millions of meteors burn up in our atmosphere each year. If they hit the ground, they are called a meteorite. Perseid Meteor Shower http: //www. montaukobservatory. com/Observer/meteor-nasa. gif

If it weren’t for the atmosphere… (Barringer Crater) in Arizona, some 38 miles east of Flagstaff, http: //woodshole. er. usgs. gov/epubs/bolide/images/meteorcrater. jpg

Meteor Impact in the Yucatan Peninsula, Mexico. This possibly killed off the dinosaurs. http: //www. worth 1000. com/entries/111000/111117 f. Kmj_w. jpg

Smaller impacts do occur but are rare. Peru, South America Peeksgill, New York http: //static. howstuffworks. com/gif/peru-meteor-1. jpg http: //apod. nasa. gov/apod/image/0611/peekskill_thomas. jpg

The Exosphere is the outermost layer. After that the area we call “outer space” begins. atschool. eduweb. co. uk/. . . /gfx/exosphere. jpg

If it weren’t for the atmosphere, our earth would look like…

http: //www. astrosurf. com/cidadao/moon_99_02_23_south. jpg The moon, with thousands of impact craters.

http: //www. abc. net. au/science/features/lunaeclipse 2007 Because the moon has less gravity and much higher temperatures than the earth, its gases get “excited” or very energetic, and are lost to space.

What is Air Pressure? Air pressure is the weight of the atmosphere pressing down on an area of the earth. http: //dogfoose. com/infotoons/

Pressure changes with altitude – the higher altitude, the lower the air pressure. htt: //images. google. com/imgres? imgurl=http: //www. physicalg eography. net/fundamentals/images/pressure_altitude. jpg&img refurl=http: //www. physicalgeography. net/fundamentals/7 d. ht ml&usg=__2 b.
