Answer 2

Force / Area
Motion, size, number of atoms

Question 3

Gravity compression

Answer 3

Gravity, acting on the mass of an object, compresses it, reducing its size and increasing the object’s density.

Question 4

Three atmospheric criteria

Answer 4

Composition
Temperature
Function

Question 5

Local Landscapes

Answer 5

Topographic features affect movement and concentration of air.
Can create barriers or conduits from place to another.
Vegetation can play a role

Question 6

Temperature Inversion

Answer 6

Layer in atmosphere in which air temperature increases wit height.

Question 7

Whats a negative about temperature inversions?

Answer 7

Stops vertical mixing and traps pollutants.
Ex: Quick cold nights, cool mountain air drains into valley.

Question 10

(Carbon Monoxide) Sources

Answer 10

Incomplete combustion (failure for carbon to burn completely because of insufficient oxygen)
Mostly vehicle emissions

Question 11

(Carbon Monoxide) Description

Answer 11

Odorless, colorless, tasteless
