Question | Answer |
a thin layer of air that forms a protective covering around the planet. | atmosphere |
earth's atmosphere is a mixture of | gases, solids, and liquids that surround the planet |
Earth's early atmosphere, produced by erupting volcanoes contained | nitrogen and carbon dioxide, but little oxygen. |
what is the most abundant gas making up to 78% of the atmosphere | nitrogen |
Oxygen makes how much % of Earth's atmosphere | 21 |
As much as four percent of the atmosphere is | Water vapor |
Other gases that make up earth's atmosphere include | argon and carbon dioxide |
Car exhaust emits gases into air true or False | True |
These pollutants mix with oxygen and other chemicals in the presence of sunlight and form a brown haze called | Smog |
how many layers are in Earth's atmosphere | five |
the lower layers include the | troposphere and stratosphere |
The upper atmospheric layers are the | mesosphere thermosphere and exosphere |
which layers contain most of the air | Troposphere and stratosphere |
which layer contains 99 percent of the water vapor and 75 percent of the atmospheric gases | Troposphere |
Which layer is directly above the troposphere,extends from 10km above Earth's surface to about 50km. | Stratosphere |
the stratosphere contains higher levels of gas called | ozone |
which layer extends from the top of the stratosphere to about 85 km above earth | mesosphere |
The thermosphere is named for its | high temperatures |
what is the thickest atmospheric layer and is found between 85 km and 500 km above Earth's surface | thermosphere |
what is the layer that is within the mesosphere and thermosphere that is electrically charged particles called | ionosphere |
The ionosphere allows radio waves to travel across the country to another city true or false | True |
Molecules closer to the surface are more densely packed that those higher in the atmosphere because of the mass of gases pressing down from higher in the atmosphere. | Atmospheric pressure |
about 19 km to 48 km above Earth in the stratosphere, this layer of 3-atom oxygen molecules protects the Earth from the Sun's harmful ultraviolet radiation | Ozone layer |
Pollutants called what are destroying the ozone layer | Chlorofluorocarbons |
CFC's are used in | Some refrigerators air conditioners, aerosol sprays, and foam packing. |
If these products develop a leak, CFC's can enter the | atmosphere |
The ozone layer has a large hole over | Antarctica |
energy that flows from an object with a higher temperature to one with a lower temperature | heat |
Energy transferred in rays or waves | Radiation |
Transfer of energy when molecules bump into each other through contact | Conduction |
Transfer of heat by the flow of a material | Convection |
What is the water that moves back and forth between Earth's atmosphere and surface | The Water cycle |
Water vapor in the atmosphere can cool and return to liquid form through | Condensation |
When water vapor condenses, clouds of tiny water | droplets may form |
As water drops grow, they fall back to Earth as | precipitation |
the movement of air from an area of high pressure to an area of lower pressure | wind |
rotation of the Earth causes moving air and water to shift to the right north of the equator and left south of the equator | the Coriolis effect |
a convection current blows wind from the cooler sea toward warmer land during the day | sea breeze |
at night, air moves off the land toward the water as the land cools more rapidly than the water | land breeze |
