Precambrian means

Answer 3

oldest preserved rocks (3900 m.y.)
- earliest fossils (bacteria 3500 m.y.)
- cells with a nucleus (1500 m.y.)
- complex organisms (700 m.y.)

Question 4

Cenozoic means

Answer 4

dinosaurs die out (65 m.y.)
- during the last half minute, humans appear
- 4600 m.y. ago the earth begins

Question 7

Weathering mean?

Answer 7

breaks down rocks by water and wind

Question 8

Erosion?

Answer 8

moves the broken pieces of rock

Question 9

What are the 3 types of rocks?

Answer 9

Sedimentary, Igneous, Metamorphic

Question 10

Sedimentary means?

Answer 10

made up of 8% of all rocks
formation energy comes from sun
formation is the result of erosion and movement of water

Question 11

Igneous mean?

Answer 11

made up of 65% of all rocks
means fire
formed by the cooling and solidification of magma
origin: volcanic

Question 12

Metamorphoic means

Answer 12

made up of 27% of all rocks
means to change
hard rocks that have changed due to increased pressure and heat

Question 13

What are the 7 landforms regions?

Answer 13

Canadian Shield, Lowlands (interior plains), Greatlakes (st. lawrence lowlands), Hudson Bay (arctic lowlands), Appalachians Mountains, Innuitian Mountains, Western Cordillera

Question 14

Canadian Shield

Answer 14

more than half of Canada
has the oldest rock in the world, igneous and metamorphic rock, many minerals, thin soil (not good for farming)

Question 15

Interior plains

Answer 15

has sedimentary rock, flat land (good for farming), wheat and barley growth
Alberta, Saskatchewan, Manitoba
glaciation created the lakes which exposed the interior plains

Question 16

Great Lakes

Answer 16

southern Canada: Ontario, Quebec
great lakes were created by glaciers
good for farming

Question 17

Hudson Bay

Answer 17

as sedimentary rock, frosted ground (no farming)

Question 18

Appalachains Mountain’s

Answer 18

oldest in Canada
east coast: Nova Scotia, New Brunswick, Newfoundland and Labrador

Question 19

Innuitian Mountains

Answer 19

covered by ice and permanent snow
high mountains
far north of Canada

Question 20

Western Cordillera

Answer 20

youngest in Canada
subduction zone
west coast: Vancouver

Question 21

6 factors that affect climate (LOWERN)

Answer 21

Latitudes
Ocean currents
Winds and Air Masses
Elevation
Reliefs
Near Water

Question 22

latitudes mean

Answer 22

quator receives most sunlight because sunun rays are more concentrated; this makes the area very warm

Question 23

ocean currents

Answer 23

the sea levels rising
warm ocean currents = warm coastal areas
cold ocean currents = cold coastal areas

Question 24

Wind and Air Masses?

Answer 24

air mass: volume of air with the same moisture and temperature throughout
wind: horizontal movements of air over the earth’s surface caused by different air pressures, winds blow from areas of high pressure to areas of low pressure

Question 25

Elevation

Answer 25

higher the elevation, colder the temperature
elevation increases, condensation increase also results in clouds and precipitation

Question 26

Reliefs

Answer 26

refers to the elevated shape of the land; the shape affects the amount of precipitation in an area

Question 27

near water

Answer 27

involves the hydrosphere and the lithosphere.

Question 28

Global Warming

Answer 28

long-term heating of the earth’s climate
observed since pre-industrial time (early 1900s)
causes: human activities, burning of fossil fuels, heat-trapping greenhouse gas levels

Question 29

Climate Change

Answer 29

long-term change in average weather patterns
has been observed since 20th century

Question 30

COP26 ?

Answer 30

international treaty on climate change
adopted by 196 countries on dec. 12, 2015; entered force on nov. 4, 2016
goal is to limit global warming to 1.5°C - finance: $100 billion from rich countries
