Definitions
The mass of air surrounding a planet
What is atmosphere?
The region of the atmosphere that extends from ground level to roughly 11 km above sea level
What is the troposphere?
The region of the atmosphere between altitudes of roughly 80 km and 460 km
What is the thermosphere?
The troposphere.
If air gets into a barometer's column, what would happen to the column?
Pressure exerted by the atmosphere on all objects within it
What is atmospheric pressure?
The region of the atmosphere that spans altitudes of roughly 11 km to 48 km
What is the stratosphere?
The region of the atmosphere above an altitude of roughly 460 km
What is the exosphere?
What are the regions you can find in the heterosphere?
Thermosphere and exosphere.
Explain the polar vortex
It is a weather phenomenon where winds blow around the South Pole preventing warmer air from entering the South Pole region resulting in very low temperatures and wind blowing upwards.
What is a barometer?
An instrument used to measure atmospheric pressure
What is the mesosphere?
The region of the atmosphere that spans altitudes of roughly 48 km to 80 km
What is the ionosphere?
The region of the atmosphere between the altitudes of roughly 65 km and 330 km, where the gases are ionized.
You have a sample of air and is composed mostly of oxygen where is it coming from?
It comes from the heterosphere.
Ozone could not be depleted by CFCs if it was for the polar vortex
What is the homosphere?
The lower layer of earth´s atmosphere which exists from ground level to roughly 80 kilometers above sea level
What are jet streams?
Narrow bands of high-speed wind that circle the earth blowing from west to east.
Mention the regions of the atmosphere?
Exosphere, mesosphere, stratoshphere, thermosphere, troposhere.
In what layer would you find the ozone layer?
In the stratosphere.
Can we say the ice freezes because of heat? Yes or No, explain
To freeze water, you need to transfer energy from water to the outside environment. This is heat.
What is the heterosphere?
The upper layer of earth´s atmosphere which exists higher than roughly 80 kilometers above sea level
What is the difference between heat and temperature?
Temperature is the measure of random motion in a substance's molecules, while heat is energy that is transferred as a consequence of temperature difference. Heat transfers from the warmer substance, to the colder substance.
Troposphere, stratosphere, and mesosphere.
In what region, temperature increase as you increase altitude?
In the stratosphere
It you see aurora in the souther hemisphere, how would you call them?
Aurora australis
