Physical Environment Interactions Pt. 2

The interaction between soil and vegetation is influenced by several factors, including the size of rock particles which determines the mineral content available to plants. True soil comprises four essential components:

Climate Regions

Atlantic

Lowest in the middle of the year

Highest at the beggining and end of a year

Goes below 0°

Lower Lakes

Gets higher throughout the year

Goes under 0°

Arctic

More in summer, less in winter

Subarctic

More in middle of the year

Low precipitation

Goes under -20°

Prarie

Low precip.

goes under 0°

Large temp. range

Mountain

High precip.

More in summer, Less in winter

Doesn't go below 0°

Pacific
Precipitation

Highprecip.

Less in summer, More in winter

Tempature

doesn't go below 0°

Small temp. range

Types of Precipitation

Convectional
5. Precipitation occurs
4. Moisture condenses into clouds
3. Air cools
2. Warm air forms and rises
1. Sun heats earth's surface
Cyclonic
6. Precipitation occurs
5. Moisture condenses into clouds
4. Air cools
3. Warm air forced up by cold air
2. Spin
1. Warm & cold air collide
relief
4. Precipitation occurs
3. Moisture condenses into clouds
2. Air cools
1. Air mass forced up by mountains

Soil & Vegetation

Which trees could survive harsh climate, Coniferous or deciduous
deciduous trees

Can not survive in winter

Coniferous trees

Their needles can conduct photosynthesis on warm days even out season

Branches and needles shack of snow easily

Have waxy needles to prevent water loss in droughts

Have sap that works as anti-freeze

They can extract minerals from bad soil

Difference between leaching and calcifiction
Calcification: Soil gives water to plants
Leaching: When soil takes water underground so plants cant use it
Why does size of rock particle matter to soil
The bigger the rock the more minerals it has
How long did it take topsoil to form
6000-1200 yrs
How is topsoil formed
Oganic materials are added to the top
Four components that make true soil
Moisture

Water dissolves nutrients into soil so plants can suck them up

Air

Plants need air in the roots

Bacteria and organic materials

Gives soil its dark color

Decomposed plants and animals. That give nutrients to plants

Minerals

Minerals needed by plants and animals

Factors Affecting Climate

L.O.W.E.R. Near water
Near Water

Closer to water bodies = colder summers, warmer winters & more precip.

Farther away from water bodies = hot summers, cold winters & less precip.

Relief

Windward = wet side

Leeward = dry side, Nickname: Rain shadow

As the moist air rises up the windward side at mountain range it expands & cools

Mountains block precipitation

Elevation

Higher elevation = more moisture

As air expands it loses heat

When air rises, it expands, because there is less air pressure

The higher the elevation the lower the temperature

Wind & air masses

Oceans contain moisture

Less precipitation inland (Continental loocation)

Air moisture releasing precipitation

Ocean Currents

When 2 currents meet the weather is often damp & foggy

Ocean currents affect the temp. of air that passes over it

Latitude

The higher the latitude the lower the temperature

Climate Basics

Temperature Range
Highest temp. minus lowest temp.
Climate Vs. Weather
Weather

Wind

Humidity

Precipitation (rain,snow,hail)

Temperature

Day to day

Climate

Average weather of a place, over long period of time

Climate Graphs

Draw bars for each month precip

Line graph showing temperature

Coneect dots with a red lign

Plot monthly values in middle of each column

Y axis on left side

Measure in°C

Climate Change

Why would warmer climate be a good thing
More space for people to live
Fewer power outages
More cruises holidays and trips
Fewer bus,plain, train delays
Longer construction season
More time at the beach
More food
Longer growing season
What are greenhouse gases
Examples

Water vapor

Ozone

Nitrous oxide

Methane

Carbon dioxide

Gases that trap heat in the earths atmosphere
The greenhouse effect
3. Greenhouse gases trp some reflected heat
2. Some heats earths surface: some is reflected
1. Solar radiation enters earths atmosphere
