Plate Tectonic Review

What are Tectonic plates?

What type of fault where the forces push on rock in opposite directions?

Type of fault that often results when rocks are pulled apart due to tension

solid, dense center of our planet

layer of the Earth is made up of tectonic plates

Theory that all continents were once connected in a single, large landmass

process by which an oceanic plate slides down the lith-asthen boundary

force that squeeze rock together and cause a reverse fault to form

When 2 TP slide past each other horizontally, the boundary is called

steep sided, loosely packed volcano formed when tephra falls to the ground

The solid center is made of primarily

Ancient continent that contained all the landmasses

Type of boundary involving a collision between 2 TP

Tectonic plates are fast

wave generated by an earthquake or volcanic eruption

magma that reaches the Earth's surface may form

Outermost, rigid layer of the Earth is called

horizontal stress

process by which an oceanic plate sinks and pulls the rest of the plate with it.

solid layers of the Earth

Which of these does not support Wegener's theory of Continental Drift

type of fault that often results when rocks are pushed together by compression

Most destructive earthquake wave

The boundary that sometimes has a subduction zone

What tectonic plate are we on

Liquid layer that lies beneath the mantle and surround the inner core

broad, gentle sloping volcano formed by quiet eruptions

opening in Earth's surface that erupts sulfurous gases

sea floor spreading occurs at which type of plate boundary

forces that push rock in opposite-but not directly opposite- horizontal directions

Thinnest layer

volcano built by alternating explosive & quiet eruptions that produce layers of tephra, & lava found at subduction zones

Process by which hot material rises and cool material sinks

Strong, lower part of the mantle that lies beneath the asthenosphere

Diameter of the Earth's core is slightly larger than the diameter of

forces that pull rock apart and can cause a normal fault

A theory says all continents were once a single landmass. What is the name of this theory?

vibrations produced when rocks break along a fault

Number of MAJOR tectonic plates

occurs when rock layer bend due to stress in Earth's crust

vertical stress that acts on the rock

Mesosphere means

soft layer of the mantle on which pieces of the lithosphere move

Tectonic plates are real

Fault often results when opposing forces cause rock to break and move horizontally
