All around us
This gas makes up the majority of the Earth's atmosphere
What is Nitrogen?
The process by which certain gases trap heat that radiate from the Earth.
What is the Greenhouse Effect?
The gas molecules that make up our atmosphere are this near Earth's surface and become less this as altitude increases.
What are densest and less dense?
This happens to molecules when they heat up.
What is the molecules start moving faster?
These are the layers of the Earth's atmosphere in order starting closest to the surface.
What are troposphere, stratosphere, mesosphere, thermosphere, exosphere?
The mass of air surrounding our planet.
What is atmosphere?
The two of the things carbon dioxide does that are essential for our planet.
What are
1) Helps regulate Earth's temperature (traps infrared light from the Earth)
2) Helps plants synthesize food?
This element is used in barometers to measure air pressure.
What is mercury?
The measure of the energy of random motion in a substance's molecules.
What is temperature?
This layer of the atmosphere contains the ozone layer.
What is the stratosphere?
Oxygen makes up this percent of the Earth's atmosphere.
What is 21%?
True or False: (if it is false, you must give the true answer.) If the carbon dioxide concentration on earth were higher, the Earth would be much colder and would not be able to support life.
What is False...the Earth would be much hotter?
This is the pressure exerted by the atmosphere on all objects within it.
What is atmospheric pressure?
Hot air is less dense (molecules are moving faster and are more spread out than cold air), which is the reason hot air does this.
Why does hot air rise?
This is what each layer between the Atmospheric layers is called.
What is a pause?
The two main things the Earth's atmosphere shields us from.
What are Meteoroids/space debris & Harmful UV rays?
Too much of the greenhouse effect is said to cause this.
What is global warming?
This is how much pressure our atmosphere exerts on every square inch it touches at sea level.
Hint: Figure 13.7
What is 14.7 psi?
Energy that is transferred from one object to another due to temperature differences.
What is heat?
This is the relationship between altitude and temperature in the Troposphere.
What is the altitude increases, the temperature decreases?
The gasses in our atmosphere give these a medium to travel through and thus make it possible for us to hear.
What are sound waves?
Two things that put carbon dioxide into the air.
What are combustion reactions and normal life processes of many creatures?
This is the result if someone empties a bottle of water on the top of a mountain, seals it, and then descends. (double jeopardy if you can tell why it happens)
What is the bottle will be crushed because the atmospheric pressure outside the bottle is greater at lower altitudes than it was when the bottle was sealed up higher?
The transfer of heat energy from molecule to molecule by contact.
What is conduction?
This region of the atmosphere helps transmit radio signals. This region is located within the upper portions of the mesosphere, the thermosphere, and the lower portions of the exosphere.
What is the ionosphere?
