ENDOGENIC PROCESSING Flashcards
What are endogenic processes?
Endogenic processes are internal processes within the Earth that lead to the formation of landforms.
True or False: Endogenic processes are responsible for shaping the Earth’s surface.
True
What is the primary driving force behind endogenic processes?
Heat from within the Earth’s interior
Fill in the blank: Endogenic processes are driven by the movement of ________ within the Earth.
magma
What type of landforms are typically formed by endogenic processes?
Mountains, volcanoes, and plateaus
How do endogenic processes contribute to the Earth’s tectonic plates?
They create and destroy tectonic plates through processes like subduction and seafloor spreading.
What is the term for the process of one tectonic plate descending beneath another?
Subduction
What landform is created when magma reaches the Earth’s surface and solidifies?
Volcanoes
is the result of the fracture or displacement of rock layer or strata along a fault plane.
faulting
How do endogenic processes contribute to the formation of earthquakes?
By the sudden release of energy along fault lines
causes squeezing, tensional stress causes stretching, and shearing stress causes side-to-side movement. Folding in rocks often results in the appearance of physical folds called anticline
and syncline.
Compressional stress
True or False: Endogenic processes are slow and gradual in nature.
False
refers to any change in the shape or size of a rock as a response to the stress
Deformation
is the result of the fracture or displacement of rock layer or strata along a fault plane.
faulting
How do endogenic processes contribute to the formation of new crust?
Through processes like seafloor spreading and volcanic activity
What is the term for the molten rock beneath the Earth’s surface?
Magma
True or False: Endogenic processes only occur at plate boundaries.
False
What is the term for the process of the Earth’s crust being forced upward?
Uplift
Fill in the blank: The process of the Earth’s crust being forced downward is known as ________.
subsidence
How do endogenic processes contribute to the formation of deep ocean trenches?
Through the process of subduction
What is the term for the process of the Earth’s crust being forced downward and creating a depression?
subsidence
True or False: Endogenic processes are solely responsible for the formation of sedimentary rocks.
False
Fill in the blank: The process of the Earth’s crust being stretched and pulled apart is known as ________.
rifting
in rocks occur when they are subjected to tectonic forces from opposite sides.
FOLDING
is the primary material extruded from a volcano in addition to volcanic rocks, ash, and dust during volcanic eruptions.
Lava
large volumes of rocks would melt within the athenosphere. The melting caused by decreasing pressure is called
pressure-release melting‘.
are the long narrow zones where one lithospheric plate descends beneath another, specifically, when an oceanic lithosphere thrusts into the mantle along a convergence. Heat in the crust and upper mantle is added as huge slabs of crust slide past each other at the subduction zones by friction,
Subduction Zones
Is the eruption of molten rock called
“magma onto Earth’s surface through a vent”.
The driving force of volcanism is the plate tectonic motion created by the movement of molten rocks in the mantle cause by
thermal convection currents’.
is when there are no movement on either side of the universe of the fracture.
a Joint
is when there is any movement on one or both sides of the fracture.
A Fault
show vertical movement at the hanging wall and the footwall.
Dip-slip faults
shows horizontal and parallel displacements of the fault planes. A transform fault,
Strike-Slip fault
which is caused by shear strain, is an example of a strike-slip fault.
A transform fault
