When the clouds become too saturated with water, the water is released as precipitation in the form of:
snow |
|
rain |
|
ice |
|
snow or ice |
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.
These clouds grow upward and can develop into cumulonimbus or thunderstorm clouds.
stratus clouds |
|
cirrus clouds |
|
cumulus clouds |
|
nimbus clouds |
Cumulus clouds are large, puffy, mid-altitude clouds with a flat base and a rounded top. These clouds grow upward and can develop into a cumulonimbus or thunderstorm cloud.

To convert from C° to F° use:
\(F° = {9 \over 5}C° + 32\)
\(F° = {9 \over 5}(5) + 32\)
\(F° = {45 \over 5} + 32\)
\(F° = 9 + 32 = 41\)
Water has a refractive index of 1.33. Which of the following is true?
light travels 1.33 times slower in a vacuum than it does in water |
|
light travels 1.33 times faster in a vacuum than it does in water |
|
light is 1.33 times brighter in a vacuum than it is in water |
|
light is 1.33 times dimmer in a vacuum than it is in water |
The speed of light varies based on the material that the waves are passing through. The refractive index of a material indicates how easily light travels through it compared to how easily light travels through a vacuum. For example, the refractive index of water is 1.33, meaning that light travels 1.33 times faster in a vacuum than it does in water.
Which of the following is not a vector quantity?
velocity |
|
mass |
|
momentum |
|
acceleration |
Velocity and displacement are vector quantities which means each is fully described by both a magnitude and a direction. In contrast, scalar quantities are quantities that are fully described by a magnitude only. A variable indicating a vector quantity will often be shown with an arrow symbol: \(\vec{v}\)
