|
Identify the terrestrial or rocky inner planets and the jovian or gas giant out planets.
|
Terrestrial: mercury, venus, earth,mars
Jovian: gas giant outer planets. |
|
|
What are some forms of evidence that the solid bodies in the solar system had a common orgin?
|
General counterclockwise rotation and orbit, similiar rotational tilt, similar orbital plane, general progression of size and distance away from the sun.
|
|
|
How does Earth differ from the other planets?
|
Abundance of water, tetonically active, magnetic field, oxygen-rich atmosphere,life,very smooth.
|
|
|
How does Earth's interior differ from its exterior?
|
Interior is molten, very hot, mostly metal; exterior is cool,rigid, brittle,mostly silicon and oxygen.
|
|
|
Troposphere
|
0 to 7 miles out from surface, warmed by Greenhouse Effect, temperature decrease with elevation as gravity weakens and air thins.
|
|
|
Stratosphere
|
5 to 30 miles out from surface, warms with elevation due to formation of ozone layer
|
|
|
Mesophere
|
30 to 50 miles out from surface, thinning air, more radiation, but very cold due to low density of gas molecules.
|
|
|
thermosphere
|
50 miles to 200mile out from surface, full intensity of solar radiation, but very low density of gases, both "very hot and very cold"
|
|
|
Greenhouse Effect
|
a natural process, mostly caused by teh absportion of terrestrial radiation by water vapor molecules in the troposhere, but also by naturally occuring levels of carbon dioxide, methane, nitrous oxide, and several otehr trace gases.
|
|
|
Global Warming
|
the artificial temperature increase caused by anthropogenic production of mainly carbon-based gases such as carbon dioxide and methane, but also some non-carbon based gses, like nitrous oxide and ozone.
