UNIT 7 Lesson 1&2
27
topography: Study of the shapes and features of the Earth's surface.
topographicmap: shows the three dimensional shape and elevations of an area of land in two dimensions.
elevation: height above sea level.
contourline: line that connects places on a topographic map that are all at the same elevation (eventually a closed loop)
contourlineinterval: the vertical difference in elevation between neighboring contour lines.
relief: the difference between the highest elevation point and lowest elevation point on a map
satellitemap: a map made of pictures of the Earth taken from a satellite orbiting the Earth.
convergent: areas where plates move toward each other and collide, causing uplift.
subductionzone: Convergent boundary where an oceanic plate is pushed beneath a continental place forming a trench. The oceanic crust melts resulting in the formation of volcanoes.
divergent: Areas where plates move away from each other, forming either mid oceanic ridges or rift valleys.
transform: Areas where two plates grind past each other resulting in faults such as the San Andreas. Earthquakes often occur at fault lines.
trench: a deep depression of the sea floor caused by the subduction of one plate under another at a convergent boundary.
riftzone: a large valley shaped area of the earth in which plates of the Earth's crust are moving away from each other, forming a system of cracks and faults.
oceanicridges: Underwater mountain ranges where the crust is spreading apart creating new ocean floor at a divergent boundary.
underwatermountainranges: Long, continuous volcanic chain of various mountains
Pangea: the super continent that existed approximately 225-260 million years ago that means 'all lands' in Latin.
Wegener: The scientist that was given the most credibility for Pangea.
lithosphere: The layer of the Earth that contains the plates.
asthenosphere: the layer of the Earth that the lithosphere floats on and contains the convection currents.
ringoffire: An area where volcanoes are concentrated on the edges of continents, along island chains or beneath the sea forming long mountain ranges.
mountainranges: A series or chain of mountains that are close together and rise 300m (1000ft.) above its surrounding area.
fault: a crack in the Earth's crust where rocks slide past one another.
theoryofplatetectonics: the theory that pieces of Earth's Lithosphere are in constant motion, driven by convection currents in the mantle.
contientaldrift: the hypothesis that the continents slowly move across Earth's surface.
convectioncurrents: the movement of a fluid, very much like a conveyor belt of thermal energy, that is the mechanism in the asthenosphere for plate movement.
subsidence: a lowering in the elevation of land.
boundary: where two plates meet.
seafloorspreading: the process by which molten material adds new oceanic crust to the oceanic floor.
theory: a well researched idea or thought that has a substantial amount of evidence to support it, but can still be disproved.
