During the water cycle, water enters the atmosphere as a gas through which process?
transpiration |
|
precipitation |
|
both evaporation and transpiration |
|
evaporation |
The water (hydrologic) cycle describes the movement of water from Earth through the atmosphere and back to Earth. The cycle starts when water evaporates into a gas from bodies of water like rivers, lakes and oceans or transpirates from the leaves of plants.
Which of the following is the correct order for types of radiation from longest to shortest wavelength?
radio waves → visible light → gamma rays |
|
microwaves → radio waves → visible light |
|
infrared waves → microwaves → ultraviolet light |
|
visible light → ultraviolet light → radio waves |
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.
An air mass is a large body of air that has which of the following characteristics?
similar moisture |
|
similar density |
|
all of these |
|
similar temperature |
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.
Which of the following is not a method of heat transfer?
reflection |
|
conduction |
|
convection |
|
radiation |
Heat is always transferred from warmer to cooler environments through conduction, convection, or radiation.
212°F is how many °C?

\(135 {5 \over 9}\) |
The formula to convert from F° to C° is:
\(C° = {5 \over 9} (F° - 32)\)
plugging in our values gives:
\(C° = {5 \over 9} (212 - 32)\)
\(C° = {5 \over 9} (180) = {{180 \times 5} \over 9}\)
\(C° = {900 \over 9}\)
\(C° = 100\)
