Flashcards in Chapter 2: Life On Land Deck (33):
1

Climatic variation is due to .....

Uneven hearing of earths surface

Due to its shape and angle of rotation

2

Cells

Warm air rises, cool air descends, creates a looping pattern

3

Coriolius effect

As earth rotates west, east winds drag with it

4

Climate diagram

Left side is temperature

Right side is precipitation

Bottom always has months

Highlighted months are above 0

5

Soil is complex, why?

Mixtures of living and non living material

6

Soil layers

LFH, A, B, C

7

Biomes

Major divisions of land environment based on specific climate with common plant species

8

Tundra biome location and area

Most North!

Covers areas of the artic

Open landscape

Many small ponds and streams

9

Tundra climate

Cold and dry

Short summers

Precipitation varies

10

Tundra soil

Permafrost

Slowly decomposing organic matter

11

Tundra biology

Reindeer, caribou, ox

Low shrubs

12

Boreal or Taiga biome land description

Wood and water cover 11% of earths land

Dense coniferous forest

13

Boreal climate

Winters longer than 6 months

Summer is too short

Low temps

14

Boreal soil

Thin. Acidic. Low fertility

15

Boreal biology

Dominated by evergreen coniferous trees

Plants used to cold

Moose, caribou, bison, wolves

16

Temperate Forest Biome description

Old Growth temperate forest

Largest living organisms in the world

Deciduous and coniferous trees

Mild winters

Severe winters or dry summers

17

Temperate forest climate

Winter last 3-4 months

Winters mild, maybe heavy snow fall

18

Temperate soil

Fertile, neutral to acidic ph

19

Temperate forest biology

Vertical stratified forest

Shrubs and saplings

Canopy top

Vast numbers of fungi and bacteria

20

Temperate grassland biome description

Largest biome in North America

21

Temperate grassland climate

Potential year long drought

Max precip during summer

22

Temperate grassland soil

Productive, deep, fertile

23

Black prairie soil contains

Most organic matter

24

Brown soil contains

Less organic matter

25

Temperate grassland biology

Dominated by vegation with great diversity

Trees and shrubs

80% biomass is under ground

26

Desert biome description

20% earths land surface

Potential drought or flash flood

Heat/ bitter cold

27

Desert climate

300mm of rain a year

Lack of water

28

Desert soil

Low organic matter

Sand and rocks

High concentrations of salt

29

Desert biology

Plant cover mostly absent

Plants have small leaves

Animal life is sparse

30

Tropical rain forest biome description

Straddle the equator

Year round warm and wet conditions

31

Tropical rain forest soil

Nutrient poor, acidic, thin

Fungi, bacteria

32

Topical rainforest biology

Insects are diverse

33

Human dominated systems

Human settlement is around food, water, suitable climate and access to trade
