Stages of Mountain Building
This is the first stage in mountain belt formation, involving thick layers of sedimentary or volcanic rock.
What is the Accumulation Stage?
The ancient, stable core of a continent.
What is a craton?
A fold where rocks arch upward, with the oldest rocks in the center.
What is an anticline?
The major normal fault here uplifted the Tetons while dropping the valley block.
What is the Teton Fault?
This California park is known for wave erosion, sea stacks, and tall trees.
What is Redwood National Park?
The stage where mountains actively form through folding and faulting.
What is the Orogenic Stage?
The process by which continents grow through the addition of land at active margins.
What is tectonic accretion?
This fault has vertical movement where the hanging wall moves downward.
What is a normal fault?
These sharp ridges and peaks, like Grand Teton, were carved by glaciers.
What are aretes and horns?
This Arkansas park is known for hot springs heated by deep groundwater and novaculite.
What is Hot Springs National Park?
In this final stage, mountains are worn down and the crust stretches, leading to faulting.
What is the Crustal Extension and Block Faulting Stage?
This U.S. coast is an example of accretion due to subduction.
What is the West Coast?
This single-bend fold is visible at Capitol Reef National Park.
What is a monocline?
The Great Basin has this kind of drainage system where water doesn’t reach the ocean.
What is internal drainage?
Located in the Basin and Range Province, this park includes the lowest point in North America.
What is Death Valley National Park?
This process causes the crust to rise after the removal of overlying weight.
What is isostatic rebound?
When this country collided with Asia, it contributed to continental growth.
What is India?
A fault type with side-to-side, horizontal movement.
What is a strike-slip fault?
These core complexes formed in the Great Basin from uplift and faulting of metamorphic rocks.
What are metamorphic core complexes?
This national park features exfoliation joints and spheroidal weathering.
What is Joshua Tree National Park?
These two geologic processes occur during the orogenic stage.
What are folding and faulting?
This type of tectonic boundary commonly leads to accretion of oceanic materials.
What is a subduction zone?
These fractures occur without any movement or displacement.
What are joints?
These ancient, long-lived trees in Great Basin can be over 4,000 years old.
What are bristlecone pines?
These adjacent parks feature glaciated granite domes and the General Sherman Tree.
What are Sequoia and Kings Canyon National Parks?
