a boundary where earth's tectonic plates move toward each other. This causes a collision or subduction. This will result in the formation of volcanoes and mountain ranges.
divergent boundary
a plate boundary where two plates move away from each other
transform boundary
a plate boundary where two plates move past each other in opposite directions
plate tectonic theory
the branch of geology studying the folding and faulting of the earth's crust
crust
the outer layer of the Earth
mantle
the layer of the earth between the crust and the core
core
the central part of the Earth
lithosphere
the solid part of the earth consisting of the crust and outer mantle
asthenosphere
the soft layer of the mantle on which the lithosphere floats
continental crust
earths crust made of land
oceanic crust
earths crust located under the ocean
subduction
a geological process in which one edge of a crustal plate is forced sideways and downward into the mantle below another plate
fault
a crack in the earth's crust resulting from the displacement of one side with respect to the other
rift valley
A deep valley that forms where two plates move apart.
trench
depression formed at a subduction zone
seafloor spreading
The process that creates new sea floor as plates move away from each other at the mid-ocean ridges
mid-oceanic ridge
The longest mountain range in the world; all along the center of the Atlantic Ocean; formed by active volcanoes through sea floor spreading
