Q

The three earth transition positions :solitces

A

Summer solitces: The Northen hemisphere is tilted towards the sun

Winter solitces: The southern hemisphere is tilted towards the sun

Vernal and autumnal solitces: sun is closest to the equator

Q

the tropics

A
  • warmest air
  • high solar isolation rates
  • air rises ( less dense)

Q

the poles

A
  • colder air
  • low solar isolation at poles leading to colder temperatures
  • denser air
  • wind currents direct water towards the poles

Q

What drives major wind currents?

A
  1. The movement of air pressure ( from high to low)
  2. Air pressure is largely determined by pressure
  3. Differential heating: higher at equator lower at pole
  4. the rotation of the earth

Q

How do we get tropical forests

A

latitudes where air rises and air cools it loses water. we get rain and tropical forests

Q

The Corolis effect explain

A
  1. The earth rotates a point at the equator moves fast than a point of latitutde
  2. laditutional differences in wind speed
  3. The northen hemisphere: deflect to the right
  4. The southern hemisphere: deflect to the left

16
Q

Function of perciptation

A

to transfer the water lost from the earth surface back into the earth via rain

17
Q

What factors effect biome distribution?

A
  • balance of evapotranspiration and percipitation and temperature
18
Q

Tundra

A
  • the coldest biome short days limit growing season
  • precipitation and evaporation are both minimal
  • lack intial rainfall
19
Q

Taiga forest

A
  • cool moist forest
  • short summer brings rain
  • plants are conifers (shrubs blueberries)
  • acidic slow decomposition plants
  • cold temperature monthly little rainfall
20
Q

Temperate Grassland

A
  • low precipitation
  • temperatures vary alot
  • disturbance by fire
  • enough moisture to support decomposition
21
Q

Desert

A
  • high temperature
  • low percipiation
  • wind patterns prevent this biome from recieving rainfall
  • deep rooted plants and cactus
22
Q

What is bio range shifts and list an example of it?

A

range shifts that happen due to climate change

example: Lobsters moving into warmer northern waters along the coast of New England

23
Q

Warm air moves from the equator to the poles

24
Q

What things effect earths seasonality?

A

the earths tilts expose different parts of the earth to more solar energy.

25
Topography:
the physical features of the earths surface that contributes to global temperatures.
26
Temperate coniferous forest
low temperature with high rainfall can occur below temperatures enormous conifers such as red cedar colder temperatures limit dedicous trees
27
Decidious forest
starts at a higher temp that coniferous forest Moderate rainfall soil rich in nutrients
28
Tropical rainforest
Heavy rains High temperatures decomposition by fungi and bacteria is very rapid
