Wednesday October 28th & Thursday October 29th

I was away sick Wednesday, so an introduction activity to Demographics was assigned. This is the first part of our new (third) unit. Students completed a textbook activity that looked at Demographics. It is due Thursday.

Thursday, we began our review for our second Unit Test. We went through each topic as a class and created a set of study notes. The first part of the study notes is copied below:


UNIT TWO: PHYSICAL GEOGRAPHY
TEST REVIEW

PLATE TECTONICS
-all the continents of the world were together...called PANGAEA (“all land”)
-the theory of continental drift was proposed
-South American & Africa fit together
-found similar fossils on different continents
-similar mountains
-ice sheets
-plates are constantly moving

Eras
-Precambrian Era, Paleozic, Mesozoic, and Cenozoic

Precambrian Era (4600-570 million yrs ago)
-Canadian Shield only part of Canada that existed
-first single & multi-celled organisms

Paleozoic Era (570-245 million yrs ago)
-first insects, plants, animals
-large part of North America were covered by shallow seas
-Appalachians were formed

Mesozoic Era (245-66 million yrs ago)
-age of reptiles (i.e. dinosaurs), first birds, mammals, flowering plants
-formation of the Rocky Mountains

Cenozoic (66 million years ago to present)
-human beings develop, age of mammals, modern forms of life evolve
-ice sheets covered most of North American at the start, continents take their present form

Rock Cycle
-types of rocks
-igneous, sedimentary, metamorphic, magma (definitions)
-rock cycle (diagram)

LANDFORMS
The Canadian Shield
The Lowlands
-The Great Lakes-St. Lawrence
-The Hudson Bay-Arctic
-The Interior Plains
The Highlands
-Western Cordillera
-Appalachian Mountains
-Innuitian Mountains
*Landforms Organizer (chart from notes)

CLIMATE
-definition of climate, weather (the difference between the two)

Factors Affecting Climate (handout fill in the blanks)
-Latitude
-further away from the equator, the cooler it is
-sun’s rays are further spread out
-Air Masses
-in Canada winds mostly blows west to east
-Elevation
-wet, warm air mass will go up one side of the mountain and become dry and cool on the other side
-Nearness to Water
-lakes and oceans change their temperature more slowly than the land around them
-Ocean Currents
-bring warm or cold air nearer to the shore
-Labrador Current (cold) and the Gulf Stream Current (warm)
-Relief
-the shape of the landform may work with any of the other climate factors to create a wet or dry, cool or warm climate

Continental Climate & Maritime Climate (definitions)

Precipitation
1. Air cool as it rises
2. As air cools, water vapour condenses more than it evaporates

Types of Precipitation (handout)
-Convectional
-Relief
-Cyclonic
(definitions, details)

Weather
-reading weather reports from newspaper

Climographs
-create a graph
-read a graph

-average annual temperature
(add 12 months together and divide by 12)
-temperature range
(subtract highest temperature from the lowest temperature)
-total precipitation
(Maritime = <1000mm)
(Continental = <1000mm)
