Continental Drift
The name given to the supercontinent formed 300 million years ago where all the Earth's land masses were together.
What is the Pangea.
This is another term for 'Landform region'.
What is a physiographic region?
These type of glaciers are found in valleys in mountainous regions.
What are Alpine glaciers?
This is found in the tundra or Arctic region. It is the soil or rock that remains frozen all year round
What is permafrost?
The name given to different layers of soil.
What is a horizon?
Name of the German scientist who first hypothesized the idea of continental drift.
Who is Alfred Wegener.
This region is also known as 'the Prairies'.
What is the Interior Plains?
These long, winding ridges of sand and gravel are often several kilometres long.
What are Eskers?
This landform region is cold and dry with very little precipitation, with a short summer and growing season.
What is the Tundra region?
Plants need this soil component mostly around their roots and within 30 cm of the surface.
What is air?
The 'jigsaw fit' of these two continents is seen as evidence of continental drift.
What is Africa and South America?
This term means 'mountainous' which describes an aspect of the western-most region of Canada.
What is cordillera?
These elongated hills shaped like inverted spoons or half-buried eggs, formed by glacial ice acting on underlying till.
What is a drumlin?
These types of trees are cone bearing and keep their needles all year long.
What is Coniferous trees?
This soil component is necessary to dissolve minerals and help in the decay of organic material.
What is moisture?
These, found on various continents with warm climates, is another piece of evidence for continental drift.
What is matching glacial deposits?
This region covers more than half of Canada and has some of the oldest rock in the world.
What is the Canadian Shield?
These “misfit” rocks are pieces of the Earth’s surface that were dropped in areas that seem odd.
What are 'erratics'.
These trees have leaves that shed at the end of the growing season. They are often called “hardwood”.
What are Deciduous trees?
This is dark in colour and found on the surface or O horizon (layer that has a high % of organic material).
What is humus?
These, similar in age and structure, are found on both sides of the Atlantic Ocean.
What are mountains similar in age and structure?
This region contains mountains made mainly of sedimentary rock.
What is the Appalachian region?
These were formed after the ice of glaciers melted and the meltwater filled in any depressions made from erosion.
What are glacial lakes?
The process by which water (rain) from the surface moves downward into the ground carrying with it the nutrients from the O horizon.
What is leaching?
This soil component is acquired through the weathering (breaking down) process into smaller elements such as sand, silt, and clay
What is minerals?
