BIS 2B UNIT 1 QUESTIONS AND ANSWERS!!
Weather
Answers :Short term, current atm conditions
Climate


Answers :average atm conditions over many years/millennia
Hadley Cell circulation


Answers :Pattern of atm circulation with warm air rising at equator and falling as
cold dry air about 30 degrees N/S.
Leads to high precipitation at the thermal equator and low precipitation at 30 N/S
Thermal equator


Answers :The area where the sun hits most intensely due to the tilt/shape of the
Earth.
The large amount of water in this area leads to warm moist area that we can see as
clouds.
Rain shadow


Answers :When air moves over water it picks up moisture. The air moves inland
and as it meets areas of high elevation the air is pushed up, making it cool down
and release moisture. When the other side is reached the air is dry (and it warms).
