Final Exam Class 1

Question 1

local, regional, and global abiotic factors result in different….that influence…

Answer 1

environmental conditions…species distribution

Question 2

geology also influences

Answer 2

environmental conditions

Question 3

what are different regions in the US drier than others?

Answer 3

mountains.

Question 4

how do mountains influence weather patterns

Answer 4

they produce extremes in precipitation on either side
- very rainy on one
-very dry on the other
(air rises over mountains and cools, rain then falls)
(loses moisture once it descends the mountain, making then air very dry on the other side of the mountain

Question 5

rain shadow example:

Answer 5

New Zealand

Question 6

why are there no deserts east of the Appalachian mountains?

Answer 6

go look it up it will be an extra credit question

Question 7

what is weather

Answer 7

short term patterns in temperature, precipitation, over hours, days, and weeks

Question 8

what are seasons

Answer 8

regular annual fluctuations in temperature, precipitation nor both

Question 9

what is climate?

Answer 9

long term patterns of temperature and precipitation based on averages and variation measured over decades

Question 10

climate influenced by:

Answer 10

regional and global factors like temp, precipitation, ocean currents

Question 11

regions near the equator receive more

Answer 11

direct sunlight,, therefore these regions are warmer over longer periods of the year

Question 12

go look at the hadley cell diagrams

Answer 12

in the powerpoint

Question 13

what are hadley cells?

Answer 13

two air circulation cells between the equator and 30 N nd 30S latitudes
they are responsible for precipitation patterns, and prevailing wind direction
the cells influence neighboring wind currents

Question 14

what are the two major efect of ind cycling patterns

Answer 14

1. rainy near equator
2. desets near 30 degrees

Question 15

hadley cells combined with… influence…

Answer 15

geology… ocean currents

Question 16

seasons

Answer 16

go look at diagram on powerpoint

what causes seasons?

Answer 17

the tilt of the earth
