Mountain Building Flashcard

Front

What factors affect the deformation of rock?

Back

Temperature, pressure, rock type, and time.

Front

What is Plastic Strain?

Back

Plastic Strain creates a permanent change in shape; when stress is removed, the rocks do not return to their original shape.

Front

What is subduction?

Back

Subduction is when one tectonic plate sinks beneath another.

Front

What geological structure results from upfolding?

Back

Anticline.

Front

How do volcanic mountains form?

Back

Volcanic mountains form when molten rock erupts on the Earth's surface, creating a mountain structure.

Front

What is the difference between Elastic Strain and Plastic Strain?

Back

Elastic Strain is temporary and returns to original shape; Plastic Strain is permanent.

Front

What is an anticline?

Back

An anticline is a type of fold that is arch-like and has its oldest rocks at the core.

Front

What is a syncline?

Back

A syncline is a fold in rock layers that is trough-like and has its youngest rocks at the core.

Front

What is the role of time in rock deformation?

Back

Time allows for the accumulation of stress and strain in rocks, affecting their deformation.

Front

What happens during the process of subduction?

Back

One tectonic plate is forced under another, leading to geological activity such as earthquakes and volcanic eruptions.
