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
