What is the tropopause? Why is the altitude of the tropopause different at the equator
versus the poles?


Give this one a try later!

, The boundary between the troposphere and the stratosphere; 1st- Solar
heating expands air and causes it to occupy more space and heating is
greatest at the equator. 2nd- Earth rotates faster at the equator than in
polar regions, therefore the atmosphere near the equator bulges outward
more than at higher altitudes, increasing its depth.




What is perihelion and when does it occur?


Give this one a try later!


When the Earth is closest to the Sun; in January




What is a map? Are all maps printed on paper?


Give this one a try later!


A flat 2D representation of Earth's surface that communicates spatial

December solstice- ssp at Tropic of Capricorn, 66.5 N and 41 N= 0-9, 41 N
and 0= 9-12, 0 and 41 S= 12-15, 41 S and 66.5 S= 15-24.
March Equinox- ssp on equator, 12 hours of daylight everywhere.
June solstice- ssp at Tropic of Cancer, flipped S to N like December

, solstice.
June Equinox- ssp on equator, 12 hours of daylight everywhere.




In what three ways is energy transferred? Give real-world examples of each.


Give this one a try later!


Conduction- the process by which energy is transferred through a
substance or between objects in direct contact. Ex: pouring coffee into a
mug increases the temperature of the mug.
Convection- transfer of heat through movement of mass within a fluid. Ex:
oven
Radiation- the process by which wave energy travels through the vacuum
of space or through a physical medium such as air or water. Ex: sun




What is aphelion and when does it occur?


Give this one a try later!


When the Earth is farthest away from the Sun; in July




What are parallels?


Give this one a try later!


Imaginary circles that run parallel to the equator and are named for their
latitudes. Ex: parallel at 40 degrees north is called the 40th north parallel
