The first step in the water cycle is:
precipitation |
|
infiltration |
|
evaporation |
|
reclamation |
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.
The number system most used in science is the:
metric system |
|
British system |
|
English system |
|
American system |
The metric system is a number system that designates one base unit for each type of measurement. For example, the base unit for length is the meter and the base unit for mass is the gram.
212°F is how many °C?
100 |
|
0 |
|
\(135 {5 \over 9}\) |
|
-100 |
The formula to convert from F° to C° is:
\(C° = {5 \over 9} (F° - 32)\)
plugging in our values gives:
\(C° = {5 \over 9} (212 - 32)\)
\(C° = {5 \over 9} (180) = {{180 \times 5} \over 9}\)
\(C° = {900 \over 9}\)
\(C° = 100\)
During the water cycle, water enters the atmosphere as a gas through which process?
evaporation |
|
precipitation |
|
transpiration |
|
both evaporation and transpiration |
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.
What type of cloud is responsible for fog?
cirrus |
|
cumulus |
|
cumulonimbus |
|
stratus |
Clouds are categorized based on their shape, size, and altitude. Stratus clouds are low-altitude clouds characterized by horizontal layering with a broad flat base. When stratus clouds occur on the ground the result is fog.
