The first stage of mountain belt building is when thick layers of sedimentary or volcanic rocks accumulate.

What is the Accumulation Stage?

100

A fold shaped like an arch.

What is an anticline?

100

A crack in Earth's crust with movement.  

What is a fault?

100

The stable interior of a continent made of very old crystaline rock.  

What is a craton?  

100

Wyoming park famous for spectacular block-fault mountains.  

What is Grand Teton National Park?

200

This mountain-building stage causes folding and faulting.

What is the Orogenic Stage?

200

A fold shaped like a trough.  

What is a syncline?

200

This fault forms when rocks are pulled apart.  

What is a normal fault?

200

The process by which continents grow through the addition of exotic terranes.  

What is tetonic accretion?  

200

Nevada park known for Basin and Range geology.  

What is Great Basin National Park? 

300

During this stage, block faulting, crust extension, uplift, weathering, and erosion occur.  

What is the Crustal Extension, Block Faulting, and the Uplift Stage?

300

In this fold, the oldest rocks are found in the center.

What is an anticline?

300

This fault forms when rocks are pushed together.  

What is a reverse fault (or thrust fault)?

300

The actual surface along which movement occurs on a fault.  

What is the fault plane? 

300

California park that is famous for giant sequoia trees.  

What is Sequoia National Park?  

400

These are the three stages of major mountain building in order.

What are Accumulation, Orogenic, and Crustal Extension/Block Faulting/ Uplift?

400

In this fold, the youngest rocks are found in the center.  

What is a syncline?

400

This fault moves primarily sideways.  

What is a strike-slip fault?

400

The rock below the fault plane.  

What is the footwall?

400

California park that contains the lowest elevation in North America.  

What is Death Valley National Park?

500

Mountain building begins during this stage rather than waiting until after sediment accumulation is complete. 

What is the Orogenic Stage?

500

A fold with only one limb, common on the Colorado Plateau and seen at Capitol Reef.  

What is a monocline?

500

The rock layer located above an inclined fault plane.  

What is the hanging wall?

500

Faults with vertical movement are collectively known by this name.
