Endogenic Process Flashcards
The surface of the earth
is broken
The pieces are large (continent size and larger)
The plates move on a plastic layer of rock in the upper mantle
Movement is very slow, but can be measured
The Theory of Plate Tectonics
➤Tectonism
➤deformation of Earth’s crust by natural processes (movements)
➤leads to the formation of continents and ocean basins, mountain systems, plateaus, rift valleys, and other features.
DIASTROPHISM
The breaking, tilting, and folding of crustal rock due to crustal movement
Deformation
squeezing of earth’s crust that compacts the rock. Convergent boundary
Compression
the pulling apart of the earth’s crust. Divergent boundary
Tension
pushes rocks side by side in opposite directions. Transform boundary
Shearing
Three basic types of plate boundaries
Divergent
Convergent
Transform
Forces in Earth’s surface caused by the movement of Earth’s plates squeezes and bends the surface of Earth.
• Folding occurs when the crust is bent upward or downward.
• Faulting occurs when the crust is actually broken.
Folding and Faulting
An _________ is the shaking and trembling that results from the movement of rock beneath Earth’s surface.
The movement is caused by _______ in Earth’s layers.
Earthquake
stress
We experience an average of _____ earthquakes everyday

________ is part of the process of bringing material from the deep interior of a planet and spilling it forth on the surface. In many cases, eruptions build up a piled of material, a mountain what is called volcano.
