1
increase in temperature with height in an atmospheric layer.
2
small particle in the atmosphere around which cloud droplets can form.
3
cloud formation that occurs when warm, moist air is forced to rise up the side of a mountain.
4
ratio of water vapor contained in a specific volume of air compared with how much water vapor that amount of air actually can hold; expressed as a percentage.
5
all solid and liquid forms of water-including rain, snow, sleet, and hail-that fall from clouds.
6
layer of Earth's atmosphere that is located above the tropopause and is made up primarily of concentrated ozone.
7
layer of Earth's atmosphere that is located above the mesopause; oxygen atoms absorb solar radiation causing the temperature to increase in this layer.
8
Layer of the atmosphere closest to Earth's surface, weather occurs here.
9
process that occurs when cloud droplets collide and form larger droplets, which eventually become too heavy to remain aloft and can fall to Earth as precipitation.
10
stored energy in water vapor that is not released to warm the atmosphere until condensation takes place.
11
the point at which water molecules leaving the water's surface equals the rate of water molecules returning to the surface.
12
layer of Earth's atmosphere above the stratopause.
13
the transfer of thermal energy between objects in contact by the collisions between the particles in the objects.
14
the transfer of thermal energy by the movement of heated material from one place to another.
15
outermost layer of Earth's atmosphere; transitional region between Earth's atmosphere and outer space.
16
the transfer of thermal energy electromagnetic waves; the transfer of thermal energy from the Sun to Earth by radiation.
17
amount of water vapor in the atmosphere at a given location on Earth's surface.
18
puffy, lumpy-looking clouds that usually occur below 2000 m.
19
a layered sheetlike cloud that covers much or all of the sky in a given area.
20
temperature to which air is cooled at a constant pressure to reach saturation, at which point condensation can occur.
21
high clouds made up of ice crystals that form at heights of 6000 m; often have a wispy, indistinct appearance.
