QuestionAnswer
What is the atmosphere? the mass of air surrounding a planet.
What is atmospheric pressure? the pressure exerted by the atmosphere on all objects within it.
What is a Barometer? An instrument used to measure atmospheric pressure.
What is the Homosphere? The lower level of earth's atmosphere, which exists from ground level to roughly 80 kilometers (50 miles) above sea levels.
What is the Heterosphere? The upper layer of earth's atmosphere, which exists higher than roughly 80 kilometers (50 miles) above sea level.
What is the Troposphere? The region of the atmosphere that extends from ground level to roughly 11 kilometers (7 miles) above sea level
What is the Stratosphere? The region of the atmosphere that spans altitudes of roughly 11 kilometers to 48 kilometers. (30 miles)
What is the Mesosphere? The region of the atmosphere that spans altitudes of roughly 48 kilometers to 80 kilometers. (50 miles)
What are Jet Streams? narrow bands of high-speed winds that circle the earth, blowing from west to east
What is Heat? energy that is transferred as a consequence of temperature differences.
What is Temperature? the measure of the energy of random motion in a substance's molecules.
What is the Thermosphere? the region of the atmosphere between altitudes of roughly 80 kilometers and 469 kilometers.
What is the Exosphere? the region of the atmosphere above an altitude of roughly 460 kilometers.
What is the Ionosphere? the region of the atmosphere between the altitudes of roughly 65 kilometers and 330 kilometers, where the gases are ionized.
If the earth's atmosphere had twice had many molecules as it does now, would the atmospheric pressure be greater than, less than or equal to what it is now?
What are the three regions of the homosphere from lowest to highest?
A plane is experiencing a lot of problem because of a storm in the area. Is the plane flying in the troposphere or the stratosphere?
Why will the ban on CFC's most likely not save or improve people's lives?
Why will the ban of CFC's most likely result in a tragic loss of human life?
Even though human civilization is responsible for less than 1% of all chlorine in the atmosphere, it is responsible for 80% of all ozone-destroying chlorine. Why?
