Competency 11 Flashcards
When categorizing landforms, what are characteristics scientists look at?
Elevation: how high
Slope
Soil type
What are landform elements?
These are parts of a landform that can be further identified (Channel in river, ridge in mountains, pool in river, peak of mountain)
What are elementary landforms?
Smallest homogeneous divisions of the land surface at the given scale/resolution
What is weather?
Condition of the air, which surrounds the day-to-day atmoshperic conditions (raining, snowing, air temp)
What is climate?
Weather over a period of time in a specific region or location
What is the climate of 4 seasons?
continental climate found in northern and central US, norhern China, south central and south easter Canada, and western and southeastern parts of the Soviet Union. cold winters, hot summers, plenty of rainfall
What is steppe or praire climate?
located in interriors of Asia and north America. Dry flat lands, away from Ocean breezes. Hot summers, cold winters. rain is less plentiful to scarce (Deserts)
What is the differnce between Tundra and Taiga?
Tundra: Marshy plain, northen areas of Russia, Europe, and Canada. Winters extremely cold, long. Ground is frozen, summer can be mushy, less snowFALL, few people, no crops can be raised (Eskomos)
Taiga: south of tundra, northern forest region, Scandenavian countries, Canada, Alaska, parts of Russia. Fur berring animals (grizzly bears). Few people, no crops raised, very cold winter temps, summer temps are cool, but hotter summer temps thatn Tundra
What is sub-tropical climate?
found north and south of tropics. Hawaii, Japan, Australia, South America. Warm current oceans cause winds to bring warm moist air in all year round. Long warm summers, short mild winters
What is the marine climate?
Western Europe, US Pacific Northwest, western coast of Canada, Southern chile. Near water, ocean winds wet and warm, mild raining climate. Summer is around 70 degrees. Winters rarely below freezing because of the ocean waters.
What is a vertical climate?
climate unique to areas of high mountains.
What are forces that have shaped the Earth’s surface?
Plate Tectonics & Continental Drift
Erosion
Weathering
Transportation of Eroded material
Deposition
Explain Plate tectonics.
Geological theory that explains continental drift, the large movement of the earth’s crust floating on the molten mantle. 10 major tectonic plates
Discuss continental collision.
when tectonic plates collide and fold up against each other
Subduction: when one plate slides under the other often results in volcanic activity
Continental collisions create high mountain ranges such as the Andes
What are rifts?
tectonic plates move away from each other, creating a hold in the middle (Mid-Atlantic Ridge). These are caused by Divergent Boundaries
