Geography's Five Themes
location, place, region, movement and human-environment interaction
its exact position on the globe
found by the lines of latitude and longitude (meridians)
its position compared to other places. can be used when dealing with regions.
character of a place
consists of the place's physical and human characterisitics
landforms, ecosystems, and climate.
humans: language? custom? live? work? economy?
is a viewpoint that is influenced by one's own culture and experiences
are areas in which certain characteristics are found throughout the area (states, countries, cities) all people are subject to the same law & ruled by the same gov't

around the core, a layer of rock
the rocky surface layer and is suprisingly thin
soil, rocks, landforms and other surface features
is the layer of the air, water and other substances above the surface
consists of water in oceans, lakes and rivers and even under the ground
the world of the plants, animals and other living things that occupy the land and waters of the planet.

Ring of Fire
a circle of volcanoes surrounding the Pacific Ocean
halves--northern, western, eastern and southern hemispheres
stands for SOund, NAvigation, and Ranging, and analyzes sounds to determine distance and direction.
landforms are usually classified by this--the difference in elevation between the highest and lowest points.
landforms are shaped first by internal FORCES that originate in the earth's interior like...
volcanism (movement of magma or molten rock), movements that fold, lift, bend or break the rock of the earth's crust
what happens when rock layers bend and buckle?
the result is a fold
stresses on rocks cause
faults, breaks in the earth's crust
whether rock layers fault or fold is determined by the
hardness of the rock and the strength of the movement
using sonar, scientists found landforms underwater closely resembles continental landforms like mountains, plains and deep canyons
rocks taken from the ocean floor were
much younger than those found on the continents...youngest found nearest the underwater ridge system (series of underwater mountains that extend around the world)
how do plates move?
convection: a circular movement caused when a material is heated, expands and rises, cools and falls (happens in the mantle)
when plates meet:
most restless place on earth.
