Endogenic Process

Question 1

Earth’s processes that occur within
or beneath the Earth’s surface that
result in reshaping the Earth’s
landforms

Answer 1

INTERNAL GEOLOGIC
(ENDOGENIC) PROCESSES

Question 2

process when a rock changes its form into a new one without undergoing melting or
disintegration.

Answer 2

Metamorphism

Question 3

Metamorphic rocks are produced from preexisting igneous, sedimentary, or from
other metamorphic rocks

Answer 3

Metamorphism

Question 4

There are two main ways that rock can go through metamorphism –

Answer 4

Contact Metamorphism and Regional Metamorphism

Question 5

This happens when rock
is heated by nearby magma.

As the magma moves
through the crust, the
rocks in the crust heat
up. The minerals in
those rocks can react to
produce new minerals.

Answer 5

CONTACT
METAMORPHISM

Question 6

During ___, high
pressures and
temperatures cause the
rock in a large area to
change.
This happens where
rock is buried deep
below the surface or
where pieces of the
Earth’s crust collide

Answer 6

REGIONAL
METAMORPHISM

Question 7

is a force that causes rocks to
change shape or volume by pushing or
pulling

Answer 7

Stress

Question 8

Three types of stress

Answer 8

compression, tension, and shear.

Question 9

is a break or crack in rock that
causes it to move.

Answer 9

fault

Question 10

the first one is the __ which is a block of rock above the fault line or above the crack in the rock,

Answer 10

hanging wall

Question 11

which is the block of rock
below the fault line.

Answer 11

footwall

Question 12

This happens when
rock is squeezed until
it folds or breaks in
convergent boundary (pushes rock together)

Answer 12

Compression

Question 13

the hanging wall
moves up the
footwall

Answer 13

reverse fault

Question 14

This happens when
the rock is pulled
causing it to be
stretched in a
divergent boundary.

Answer 14

Tension

Question 15

The type of fault in a
tension stress is a
normal fault.

Answer 15

Tension

Question 16

the hanging wall
moves down along
the fault line.

Answer 16

normal fault,

Question 17

This happens when
rocks moves
sideways until they
bends or breaks in a
transform boundary.

Answer 17

Shear

Question 18

It occurs when the forces
that push rocks and faults
in opposite directions.

Answer 18

Shear

Question 19

results when the adjacent
blocks of rocks move sideways
and not up and down.

Answer 19

Strike slip

Question 20

is the process by which the
crust is deformed along
tectonic plate margins.

Answer 20

Deformation

Question 21

can be defined as bend in rock
that is response to compressional force.

▪ This occur when rocks are pushed towards each other from opposite sides. Some rocks do not break when under stress. Instead, the rocks bend or crumple.

Answer 21

fold

Question 22

a convex up
fold in rock that resembles
an arch like structure with
the rock beds (or limbs)
dipping away from the center
of the structure.

Answer 22

anticline

Question 23

is a type of fold
where the rock layers are
warped downward.

Answer 23

syncline

Question 24

form in rocks when the stresses
overcome the internal strength of the rock resulting in a fracture

Answer 24

Faults

Question 25

produced when tensional
stresses result in the subsidence of a block of
rock.

Answer 25

Graben fault

Question 26

is the development of two reverse
faults causing a block of rock to be pushed up

Answer 26

Horst fault

Question 27

cuts through the
lithosphere and accommodates motion between two large crustal plates

Answer 27

transform fault
