List the layers contained in the atmosphere and describe what is in each layer.
lisabon 2012 [21]

Answer:

Exosphere -The exosphere layer is mainly composed of extremely low densities of hydrogen, helium, and several heavier molecules including nitrogen, oxygen, and carbon dioxide closer to the exobase. The atoms and molecules are so far apart that they can travel hundreds of kilometers without colliding with one another.

Thermosphere - The aurora (Northern Lights and Southern Lights) mostly occur in the thermosphere. The thermosphere is a layer of Earth's atmosphere. The thermosphere is directly above the mesosphere and below the exosphere. ... Temperatures in the upper thermosphere can range from about 500° C (932° F) to 2,000° C (3,632° F) or higher.

Mesosphere- Most meteors burn up in the mesosphere. A type of lightning called sprites sometimes appears in the mesosphere above thunderstorms. Strange, high-altitude clouds called noctilucent clouds sometimes form in this layer near the North and South Poles.

Stratosphere-The stratosphere is the second major atmospheric layer above the troposphere, extending in altitude from about 8 to 30 miles high. No weather occurs in the stratosphere. The statosphere contains over 15% of the total mass of the atmosphere, and is where the ozone layer is located.

Troposphere-The troposphere is the lowest layer of Earth's atmosphere, and is also where nearly all weather conditions take place. It contains 75% of the atmosphere's mass and 99% of the total mass of water vapour and aerosols.

i hope this helps, good luck :)

guapka [62]

Answer:

My hypothesis is that the Hawaiian Island chain was formed by a hot spot in the middle of the Pacific Plate. While the hot spot itself is fixed, the plate is moving. My data supports my hypothesis because as the plate moved over the hot spot, the islands that make up the Hawaiian Island chain were formed.
