- 1A long time ago it is said that all the continents were one super continent that was called...Pangea
- 2It is said that the continents used to be one then detached what theory is this calledthe continental drift
- 3who is responsible for the theory of the continental driftAlfred Wegener
- 4What are Alfred Wegener's 4 proofs of the continental drift1. there are fossils of similar animals of completely different continents
2. There is evidence of ice sheets on places that are currently really warm
3. the continents fit together like puzzle pieces
4. there are rock formations of similar age and structure, on different continents - 5How many major plates make up the earth's crust13
- 6what plate is Canada part ofthe North American plate
- 7how do plates moveconvection currents (when hot magma moves to the surface then cools down and repeats)
- 8what are the 3 ways plates meetdivergent (move away from each other)
convergent (move toward each other)
transform (slide past each other) - 9what are 2 plate boundary hazardsvolcanos, earthquakes
- 10what are the 4 layers of the earthcrust
mantle
outer core
inner core - 11is the outer core solid or liquidmolten (in between)
- 12is the inner core solid or liquidsolid
- 13what are the 4 eras in earth's geological history in order from oldest to newestPhanerozoic
Paleozoic
Mesozoic
Cenozoic - 14what does LOWERN stand forLatitude
Ocean current
Wind
Eleveation
Relief
Near water - 15what are 3 forces that erodewind
water
ice - 16the rock cycle in order starting from lavaLava
igneous
sedimentary
metamorphic - 17define lavamolten rock
- 18define igneous rockcooled lava
- 19define sedimentary rockigenous rock that has been weathered, eroded, displaced and cemented
- 20Name the land forms in CanadaWestern Cordillera
St.Lawrence lowlands
Canadian shield
Interior Plains
Arctic lowlands
Hudson Bay lowlands
Appalachian region
Innuitian Mountains - 21what are the 2 types of glaciersalpine, and continental
- 22when did the last major ice age in Canada beginabout 100 000 years ago
- 23when did the last major ice age in Canada end and wheresouthern ontario 10 000 years ago
- 24when more snow is added and the ice moves outward this is calledglacial accumulation
- 25If melting happens faster than accumulation the glacier goes throughglacial retreat
- 26how do alpine glaciers movewith the help of gravity
- 27how do continental glaciers movetheir own weight
- 28A horn, a U-shaped valley, striations and a cirque are all what type of featureserosion
- 29when a mountain is weathered on both sides it creates a steep sided peak called a what?horn
- 30When jagged mountain valleys become smooth and u-shaped after the glacier retreats. The ice (and rocks in it) scrape the valley floor and sides. The result is called a what?U-shaped valley
- 31Rocks in the glacier carve long grooves in the bedrock, direction of grooves shows which way the glacier traveled. These are called what?Striations
- 32A Bowl-shaped depression where glacier starts, created by physical weathering and weight of glacier. Is called a what?Cirque
- 33A till, moraines, a drumlin, an erratic, an esker, kettle lakes and a kame are all what type of featuresdeposition features
- 34Material picked up and carried by glacier, made up of very fine particles of sand, to huge boulders. is called what?a till
- 35Ridges of till left at the front or sides of a glacier as it retreats, and show how far it advanced. Are called what?Moraines
- 36Egg shaped hills that occur in clusters. Used for farming due to the soil deposits, and are mined for gravel. Is called a what?A drumlin
- 37Large boulder carried by the ice to a spot where it is dropped. Easily spotted, since they are usually unlike the rock around them. Is called a what?an erratic
- 38A long sinuous ridge of sand and gravel deposited by water flowing under a glacier or ice sheet. is called a what?an esker
- 39Deep small lakes formed from ice chunks lodged into the ground, are called what?kettle lakes
- 40Steep mounds or conical hills built by material dropped in holes in the ice. are called what?a kame
- 41what is isostatic rebound?when the ground bounces back up after being held down by the weight of a glacier
- 42what are the 2 types of climate?maritime, and continental
- 43somewhat constant temperature and a lot of precipitation is what type of climatemaritime
- 44a varied temperature that increases and decreases during different times with an average amount of precipitation is an example of which climatecontinental
- 45how much precipitation does a growing season need and how long do growing seasons last?500 mm and 6 months
- 46what created the great lakesglaciers
- 47what is happening to the great lakes now?they are still forming
- 48Are the Appalachians older than the western cordillerayes
- 49what type of rock can you find in the interior plainsmainly metamorphic and igneous
- 50what are the climate regions of Canadaarctic, pacific maritime, cordilleran, taiga, boreal, prarie, atlantic maritime, southeastern
- 51what is intrusionwhen the magma is pushed upwards and cools forming something almost like a volcano
- 52what is an eruptionwhen magma bursts through the crust of the earth
- 53What are the two continents after Pangaea splitLaurasia and Gondwanaland
- 54What is the current name given to the movement of the platesplate tectonics
- 55What plate boundary creates new landdivergent
- 56what is the maritime range for temperature and precipitationtemperature: <25 degrees C
total precipitation: >1 000 mm - 57what is the continental range for temperature and precipitationtemperature: >25 degrees C
total precipitation: < 1000 mm
