Wegener's Theory
What is one of the slabs of rock that Earth's lithosphere is broken up into?
Tectonic Plates
These only grow in tropical and subtropical regions but are found in colder regions today
coal deposits and Coral reefs
Shield volcanoes often form here
hot spots
The Earth has this many major Tectonic Plates
Seven
What is along the line of sea floor mountains where new crust forms?
Mid Ocean Ridge
What is Earths crust and very top mantle combined?
Lithosphere
This part of the Earth is divided up into plates.
Lithosphere
What is a gap that forms where continental tectonic plates move apart.
Rift Valley
The type of boundary and the direction of its movement determine this
Plate boundary interactions
These can be created by underwater volcanoes or rapid plate movement in the ocean
Tsunami
Fossils of these have been found on different continents and support the CDT
The same species organisms
These maps were created by scientists using echo sounders in the ocean in the 1950s.
Bathymetric maps
this occurs when hot materials rises at mid-ocean ridges and sinks at deep ocean trenches
Convection current
This is a boundary where 2 tectonic plates move apart and new ocean crust is formed.
Divergent boundary
This crust is both dense and found underwater
Oceanic Crust
This was the name given to the supercontinent that formed previous to Pangea in the continental drift hypothesis?
Rodinia
What is the layer of hotter, softer rock in the upper mantle?
Asthenosphere
This force pulls on Earth's crust stretching the rock to make it thinner
tension
This is a zone where one oceanic plate is force beneath another plate.
Subduction Zone
This is the total energy released by an earthquake.
Magnitude
Grooves and rock deposits on different continents close to the equator were left by these?
Glaciers
At a convergent boundary water may be trapped and mix with carbon and mantle material resurfacing in the Earth as one of these
Volcanoes
Convergent oceanic continental boundary often form these farther into the continental crust usually among Mountain ranges.
Continental volcanic arcs
What is a fracture in the continuity of a rock formation caused by a shifting or dislodging of the earth's crust?
Fault line
Volcanic activity that takes place away from plate boundaries is called this
Intraplate activity
