Folding and Faulting Flashcard

A fold is a bend in rock layers that occurs due to stress in the Earth's crust.

A syncline is a downfolded portion of rock layers.

An anticline is an upfolded portion of rock layers.

A fault is a fracture in the Earth's crust where pieces of earth move up, down, or sideways.

Shear stress occurs at transform boundaries where plates slide past each other.

Tension pulls rock apart, while compression pushes rock together.

Igneous rock is formed when magma cools and solidifies.

A volcano is an opening in the Earth's crust through which magma, gases, and ash erupt.

Earthquakes are caused by the sudden release of energy in the Earth's crust, often due to movement along faults.

The Earth's crust is the outermost layer of the Earth, composed of rock and soil.
