Climate
Average weather condition of a place studied of a long period of time. Climatology concerns itself with the same elements of weather but over a longer time scale.

New cards
The properties of air vary with [blank]?
Distance from the Earth's surface
4
New cards
The sun heats the surface of the Earth, some of this heat goes into [blank]?
Warming the air near the surface, which then goes into the atmosphere
5
New cards
Air Temperature is highest [blank]?
Near the surface and decrease with altitude
6
New cards
What is the pressure of air related to [blank]?
The weight of air over a given location
7
New cards
Thin air exerts less pressure than air at a [blank]?
Lower altitude

Air Density
Depends on both temperature and the pressure through the equation of state - Also decreases with altitude

The atmosphere
-Contained within a relatively shallow envelope surrounding the planet -8000 mile diameter and 60 miles thick -Not uniform; fluid properties are constantly changing with time and location
-The outer atmosphere beginning from about 50 miles from the earth's surface and extending to space -Gases are not evenly mixed but assorted by gravity according to their atomic weight and reaction of the gases with solar radiation -Less than 0.001% of the mass of th4e earth's atmosphere is in the heterosphere

New cards
Homosphere
-Extends from the Earth's surface to about 50 miles -Density of air changes with altitude bet the proportion of gases is nearly uniform -Exceptions are: Ozone, Water Vapor, Pollutants, and Some trace chemical.
