What layer of the atmosphere is ozone in?
The stratosphere
True or false. The temperature in the stratosphere increases due to the presence of the ozone layer.
True
What does the ozone layer do?
Absorbs harmful UV radiation coming from the sun
Human activity has depleted ozone by adding what?
Chlorofluorocarbons (CFCs)
Where are the largest and smallest ozone holes?
The largest is in south pole/the smallest is in the north pole
What layer of the atmosphere do meteors tend to burn up in?
The mesosphere
What layer does aurora’s occur in?
The thermosphere
True or false. there is no defined upper limit due to the low concentration of gases
True, but the upper portion is generally considered to be the Thermopause
Gases move at high speeds due to the absorption of incoming solar radiation in which layer of the atmosphere
Thermosphere
Which one of the earth’s motions gives us night and day?
Rotation. The Earth rotates on its axis.
Summer occurs when the sun is at the…
Highest angle 
True or false. When the sun is at a lower angle, there is more diffused light and it is cooler.
True
Heat equals… Energy
Temperature is the average… Energy
Heat= thermal
Temperature= kinetic
What are the three mechanisms of heat flow?
Conduction, convection, radiation.
What is the transfer of heat through bulk motion of fluids?
Convection
What is the transfer of energy(heat) through electromagnetic waves
Radiation
What is the transfer of heat through matter?
Conduction
Atmospheric affects
Reflection, scattering, absorption, and refraction
What is radiation that is absorbed and radiated back into the atmosphere, only longer wavelength of radiant energy
Terrestrial radiation
When short wavelength radiation from the sun is transmitted through earths atmosphere, it interacts with matter and can be reradiated as long wavelength energy that is now trapped in earth atmosphere (or just heating in the atmosphere)
Greenhouse effect
Gases that often absorb and reabsorbed are called…
Greenhouse gases
True or false. climate change is energy, absorbed from the sun that varies overtime, which differs from global warming, which is human induced
True
True or false. Locations by the water take longer to cool down and heat up.
True
