Earths biome

Question 1

What controls the environments temperature?

Answer 1

the angle of incoming solar radiation

Question 2

The three earth transition positions :solitces

Answer 2

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

Question 3

the tropics

Answer 3

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

Question 4

the poles

Answer 4

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

Question 5

How would the earth air move if it didnt rotate

Answer 5

high pressure to low pressure

Question 6

Hadley cells

Answer 6

the rising and falling of air masses

Question 7

How does air move?

Answer 7

From areas of high pressures to areas of low pressure

Question 8

What drives major wind currents?

Answer 8

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

Question 9

Doldrums

Answer 9

areas between all the cells where horizontal winds are low

Question 10

How do we get tropical forests

Answer 10

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

Question 11

How do we get deserts

Answer 11

air descending

Question 12

The Corolis effect explain

Answer 12

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

Question 13

What two things drive major ocean currents

Answer 13

Winds and the Corolis effect transporting heat on earth

Question 14

What determines the type of terrestrial biome?

Answer 14

• The supply
• The demand of water

Question 15

Evapotranspiration

Answer 15

evaporation lost from the earths surface + transpiration of plants

Question 16

Function of perciptation

Answer 16

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

Question 17

What factors effect biome distribution?

Answer 17

• balance of evapotranspiration and percipitation and temperature

Question 18

Tundra

Answer 18

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

Question 19

Taiga forest

Answer 19

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

Question 20

Temperate Grassland

Answer 20

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

Question 21

Desert

Answer 21

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

Question 22

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

Answer 22

range shifts that happen due to climate change

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

Question 23

Warm air moves from the equator to the poles

Question 24

What things effect earths seasonality?

Answer 24

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

Question 25

Topography:

Answer 25

the physical features of the earths surface that contributes to global temperatures.

Question 26

Temperate coniferous forest

Answer 26

low temperature with high rainfall

can occur below temperatures

enormous conifers such as red cedar

colder temperatures limit dedicous trees

Question 27

Decidious forest

Answer 27

starts at a higher temp that coniferous forest

Moderate rainfall

soil rich in nutrients

Question 28

Tropical rainforest

Answer 28

Heavy rains

High temperatures

decomposition by fungi and bacteria is very rapid
