What is the correct order for the 5 layers of the atmosphere, starting with the lowest layer?
a) stratosphere, exosphere, mesosphere, thermosphere, troposphere
b) troposphere, mesosphere, thermosphere, stratosphere, exosphere
c) thermosphere, stratosphere, mesosphere, troposphere, exosphere

What is in the stratosphere and one molecule of it is made up of 3 oxygen atoms? It absorbs UV radiation.
a) ozone layer
b) x-ray layer
c) microwave layer
d) heat layer

What is the process in which warm air rises, then cools, then sinks, then gets warm again and the process starts over?
a) conduction
b) convection
c) radiation
d) advection

As air pressure decreases, we can expect warmer weather. Why?
a) Because when air pressure decreases, the particles hit each other more often, therefore increasing the temperature.
b) A higher temperature means the particles are moving slower and therefore under lower pressure.
c) A higher temperature means the particles are moving faster,more spread out,less dense,and therefore under low pressure.
d) A higher temperature means the particles are closer together and therefore under lower pressure.
