Question | Answer |
The atmosphere was formed by | a direct act of God during the Creation week |
The most abundant gas in the homosphere | Nitrogen |
The gas called ozone is composed of | Oxygen atoms |
Atmospheric layer that directly affects radio communications on Earth | Ionosphere |
Layer most effective in protecting the earth from solar flare | Magnetosphere |
Results in earth's surface absorbing the most heat from the sun | clear & cold with low humidity |
Not significantly affected by variation of oxygen in the atmosphere | Greenhouse warming of earth |
When the earth's surface warms the air directly above | Conduction |
An optical illusion | Mirage |
The amount of water vapor present in the air compared to the amount it could hold | Relative humidity |
Water cannot enter the atmosphere by | Condensation |
When humid air mass is lifted higher into the atmosphere, at some point it begins to form clouds as its water vapor condenses. What causes this condensation to take place? | Adiabatic cooling |
Prefix used when naming medium-altitude cloud types | Alto |
Cloud that never produces rain | Cirrus |
Not associated with cirrus clouds | Composed of supercooled water |
Forms of precipitation | Rain, snow, hail |
Natural unpollued rainwater is | slightly acidic |
Winds flowing from different directions that come together in a locality force air masses aloft. Cloud formation and storms are often the result. | Convergence |
Snow forms when water vapor in the atmosphere | Sublimes |
Type of clouds hail usually form | Cumulonimbus |
Temperature at which the relative humidity is equal to 100% | Dew point |
Liquid water below the freezing point | Supercooled water |
Three basic cloud shapes | Stratus (flat), Cumulus (piles), Cirrus (wispy curls) |
Top of the cumulonimbus cloud is often shaped like an | anvil |
Raindrops form as large cloud droplets begin to fall and collect other cloud droplets in this process. | Coalescence |
Most brief showers or thunderstorms that occur in the summertime are the result of | Convection |
Three types of solid precipitation | Snow, sleet, hail |
T/F: It is possible for liquid water and water vapor to exist at the same temperature | True |
T/F: Water can evaporate without being warmer than its surroundings | True |
T/F: The higher the temperature of the air, the more moisture it can hold. | True |
T/F: Nimbus-type clouds often bring rain. | True |
T/F: Drizzle is a form of freezing rain. | False |
T/F: Low clouds cause a halo to appear around the sun or moon. | False |
T/F: A mackeral sky is caused by altostratus clouds. | False |
T/F: Dew forms when warm air cools below the freezing point. | False |
T/F: The only acidic precipitation is acid rain. | False |
T/F: All forms of precipitation result in some way from the cooling of a relatively warm, humid air mass. | True |
T/F: God created the atmosphere on the second day of the Creation week. | True |
T/F: The percentage of gases in the himosphere remain relatively constant. | True |
T/F: The continuous mixing of cold and warm air occurs only in the troposhere. | True |
T/F: The troposphere is the only atmospheric layer to have winds. | False |
T/F: Since warm air rises, the troposphere is the coolest layer of the atmosphere. | False |
T/F: Auroras occur when charged particles escape from the ionosphere into the magnetosphere. | False |
The envelope of gases surrounding the earth | Atmosphere |
Fast winds that travel in paths in the stratosphere. | Jet streams |
Indirect warming of the atmosphere. | Greenhouse Effect |
The study of the atmosphere. | Meteorology |
The condition of the atmosphere at any given time. | Weather |
An indication of the amount of thermal energy in the air. | Temperature |
Weight of atmospheric gases per unit area. | Atmospheric pressure |
The amount of water vapor actually present in the atmosphere. | Absolute humidity |
Who is credited for discovering oxygen? | Joseph Priestly and Karl Scheele |
The coldest temperatures of the atmosphere are found at the top of this layer | Mesosphere |
Five conditions usually included in the description of the weather. | Temperature, atmospheric pressure, precipitation, wind speed and direction, humidity |
