copy deck
Five themes of geography?
Location, Place, Human-Environment Interaction, Movement, and Regions.
What is involved in the study of geography?
People, places, and things and how they relate to each other, earth's surface cultures and economics, relationships between people and their evironment.
Absolute Location
A place's position on the globe. (40'N, 80'W)
An imaginary line that cirlces the globe halfway between the North and South poles.
Formal Region
An area in which a certain characteristic (attribute) is found throughout the area. (Example: Corn Belt)
Functional Region
A central place and the surrounding places affected by it. (Examples: Boston Metropolitan Area or Railsystem)
The study of wherepeople, places, and things are located and how they relate to each other.
One of two equal halves of the earth.
Imaginary lines that run parallel to the Equator. (Run West-East)(example: 10'N)
Imaginary lines that run North and South. (example: 26'E)
Prime Meridian
An imaginary line from which other meridians are measured.
Relative Location
A place's position in relation to other places.
Landforms, climate and vegetation are:
Physical characteristics of places.
Irrigation system, houses, and roads are examples of:
people changing environments.
The solar system is NOT part of geography. (True of False)
True- The solar system is not geography.
An example of International Trade is:
movement of people, goods and ideas between places.
The center of the Earth.
A break in the earth's crust.
The thick layer of rock around the earth's core.
The difference in elevation between a landform's highest and lowest ponts.
Earth's thin, rocky surface.
The earth is a planet affected by?
Landforms on the earth's surface are created and changed by?
internal forces
According to the theory of plate tectonics, the earth's outer shell consists of:
a number of large, moving plates.
Circular movement of heat below the earth's surface, or convection, causes:
volcanoes to erupt.
Volcanoes and earthquakes are likely to occur:
where plates collide or pull apart.
What are the largest landmasses in the earth's oceans?
Study of the earth's physical structure and history.
Bend or buckling of the earth's crust.
Plate Tectonics
theory that the earth's outer shell is not one piece of rock.
Continental Drift Theory
Idea that all continents were once a single landmass but are now separate.
Ring of Fire
Circle of volcanic mountains around the Pacific Ocean.
Molten rock that flows from a volcano.
Chemical or mechanical process by which rock is gradually broken down.
Mechanical Weathering
the actual breaking up or physical weakening of rock by forces such as ice and roots.
Chemical Weathering
Process by which the actual chemical structure of rock is changed.
Acid Rain
Rain with highconcentrations of chemicals that kills plant and animal life and eats away at the surface of stone and rock.
The movement of weathered materials usually caused by water, wind and glaciers.
Small particles of soil, sand, and gravel carried and deposited by water.
Fine-grained, mineral-rich loam, dust, or silt deposited by winds.
Huge, slow-moving mass of snow and ice.
Ridge-like mass of rock, gravel, sand, and clay carried and deposited by a glacier.
Two important forces in chemical weathering are:
Water and Carbon Dioxide
Three most common causes of erosion?
Water, Wind, and Glaciers
Dust Bowl is in?
North America
Continent covered by glaciers?
