An air mass is a large body of air that has which of the following characteristics?
similar moisture |
|
similar temperature |
|
similar density |
|
all of these |
An air mass is a large body of air that has similar moisture (density) and temperature characteristics. A front is a transition zone between two air masses.
When the clouds become too saturated with water, the water is released as precipitation in the form of:
snow or ice |
|
ice |
|
snow |
|
rain |
Rising into the atmosphere, the water condenses into clouds. When the clouds become too saturated with water, the water is released as snow or ice precipitation which may warm as it falls to reach Earth as rain.

To convert from C° to F° use:
\(F° = {9 \over 5}C° + 32\)
\(F° = {9 \over 5}(0) + 32\)
\(F° = 0 + 32 = 32\)
Elements in the Periodic Table of the Elements are ordered by which of the following?
number of electron shells |
|
atomic weight |
|
atomic number |
|
atomic mass |
The Periodic Table of the Elements categorizes elements primarily by the number of protons in their nucleus (atomic number) and secondarily by the characteristics they exhibit.
As part of the carbon cycle, plants release carbon into the atmosphere through which process?
photosynthesis |
|
sedimentation |
|
decomposition |
|
evaporation |
The carbon cycle represents the ciruit of carbon through Earth's ecosystem. Carbon dioxide (CO2) in the atmosphere is absorbed by plants through photosynthesis. Plants then die and release carbon back into the atmosphere during decomposition or are eaten by animals who breathe (respiration) the carbon into the atmosphere they exhale and produce waste which also releases carbon as it decays.
