Understanding the Pieces Flashcards
he is a German meteorologist and geophysicist, who hypothesized and suggested that the landmasses of Earth were once merged into a supercontinent. He is also known as the father of the place tectonics theory
Alfred Wegener
This is known for being the Earth that was once merged into a supercontinent
Pangaea
is a theory about how Earth’s lithosphere is divided into a series of rigid plates; and, how movements of these plates produce earthquakes, volcanoes, ocean trenches, mountain ranges, and more.
plate tectonics
“tectonic”
to build
it is the rigid outer part of the earth, consisting
of the crust and upper mantle
lithosphere
it is thicker and less dense crust, which makes it “float”
continental crust
it is made of various types of rocks and sediments floating on top of the malleable upper mantle that extends from the surface to about 50 km deep.
crust
it is a denser and relatively thinner crust
oceanic crust
the plate tectonic theory suggests that the lithosphere is divided into fragments known as?
plates
this is used to find the epicenter
triangulation method
it is when the magma builds a series of volcanoes
volcano arc
this is the region where volcano arcs are found
Pacific Ring of Fire
are the smallest section of Lithosphere.
tectonic plates
are the edges of plate tectonics that separates each tectonics.
plate boundaries
refers to the movement of
the Earth’s lithospheric plates.
