When the clouds become too saturated with water, the water is released as precipitation in the form of:
ice |
|
snow |
|
snow or ice |
|
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.
Which of the following is the correct order for types of radiation from longest to shortest wavelength?
infrared waves → microwaves → ultraviolet light |
|
visible light → ultraviolet light → radio waves |
|
radio waves → visible light → gamma rays |
|
microwaves → radio waves → visible light |
The electromagnetic spectrum covers all possible wavelengths and frequencies of radiation. From lowest frequency (longest wavelength) to highest frequency (shortest wavelength) radiation: radio waves → microwaves → infrared waves → visible light → ultraviolet light → X-rays → gamma rays.
Which of the following is the formula for work?
\(W = {\vec{F} \over \vec{d} }\) |
|
\(W = {{F}\over{d}}\) |
|
\(W = \vec{F}\vec{d}\) |
|
\(W = {F}{d}\) |
Work is performed on an object when an applied force causes displacement along the same vector. Measured in joules (J) or newton-meter (Nm), work is calculated by multiplying force times displacement: \(W = \vec{F}\vec{d}\)
In the water cycle, infiltration is most closely related to:
water table |
|
runoff |
|
rivers |
|
oceans |
The water then accumulates as runoff and eventually returns to bodies of water or is absorbed into the Earth (infiltration) and becomes part of the water table, an underground resevoir of fresh water.
What kind of weather front is likely to create clouds and storms?
warm front |
|
cold front |
|
stationary front |
|
temperate front |
A warm front is the boundary between warm and cool (or cold) air when the warm air is replacing the cold air. Warm air at the surface pushes above the cool air mass creating clouds and storms.
