What are the 5 themes of geography?
Location, Place, Region, Movement, Interaction
imaginary lines on the map that run parallel to the Equator, they measure the distance north and south of the Equator
imaginary lines on the map that run north and south between the two poles
Where is the Equator
in the middle of the earth, zero degrees latitude
Where is the relative location of the Tropic of Cancer
between the Arctic Circle and the Equator, 20 degrees North latitude
Where is the Prime Meridian
It is 0 degrees and runs through the Royal Observatory in Greenwich, England
What do we determine using the meridians on the globe?
What city boasts that it is the home of the Prime Meridian
Explain the Theory of Plate Tectonics?
The theory that the earth's outer shell is composed of a number of large, unanchored plates, or slabs of rock, whose constant movement explains earthquakes and volcanic activity
When plates meet and push or pull away from each other it causes?
rift valley, earthquakes, and volcanic action
What is the Ring of Fire?
a circle of volcanoes surrounding the Pacific Ocean
What does a relief map show you?
the differences in elevation, or height, of the landforms in any particular area
A raised area or mound of land
a very tall high, natural place on Earth, higher than a hill
a large, flat area of land that is higher than the surrounding land
flat lands that have only small changes in elevation
a group or chain of islands clustered together in a sea or ocean
a body of water that is partly enclosed by land (and is usually smaller than a gulf)
a flat-topped rock or hill formation with steep sides
a narrow body of water that connects two larger bodies of water
a narrow strip of land connecting two larger land masses. An isthmus has water on two sides
an area of land that is often wet; the soil in wetlands are often low in oxygen. types include: swamp, slough, fen, bog, marsh, moor, muskeg, peatland, bottomland, mire, delmarva, wet meadow, riparian, etc
a deep valley with very steep sides, often carved by a river
hills at the base of a mountain range
a wide, relatively flat are of land that has grasses and only a few trees
a cold, treeless area; it is the coldest biome
a large body of water surrounded by land on all sides. Really large lakes are often called seas
the condition of the bottom layer of the earth's atmosphere in one place over a short period of time
the term used for the weather patterns than an area typically experiences over a long period of time
8 things that affect the world's climate
sun, greenhouse effect, solar radiation, elevation, precipitation,
bodies of water, wind, currents, nearby landforms
What is the greenhouse effect?
the earth's atmosphere which prevents heat from escaping back into space too quickly
why do we have seasons?
because of the earth's tilt and revolution around the sun
either of the two times of the year when the sun appears directly overhead at the Tropics of Cancer and the Tropics of Capricorn
either of the two times each year (spring and fall) when day and night are nearly equal length everywhere on earth
What is it like at the equator?
hot and dry
What is it like at the North Pole?
What is it like at the South Pole?
What would it feel like in the temperate zone?
cooler than the tropics and have a wide range of temperatures
How do ocean currents affect climate?
warm and cold ocean currents, like the winds, help distribute heat from the regions near the Equator to the polar regions
What is an ecosystem?
The interaction of plant life, animal life, and the physical environment in which they live
What is a biome?
the term used to describe a major type of ecosystem that can be found in various regions throughout the world
what are the 4 ecosystems?
forest regions, grasslands, desert, tundra
the four major parts of a map
key, title, scale, compass rose (which always points north)
