1.4 - Volcanoes, Folding and Faulting

Earthquakes occur most commonly along:

The point on the Earth’s surface directly above an earthquake’s focus is the:

When the crust is compressed, rock layers usually:

An upfold in rock layers is called a(n):

Fold mountains form mainly at:

A fault is best described as:

A downfold in rock layers is called a(n):

A steep ‘step’ in the landscape formed by vertical fault movement is known as a fault:

A block of land that drops down between two faults forms a:

A block of land that is uplifted between faults is called a:

A map of a Caribbean island shows a long, straight valley aligned with a known fault zone. The best explanation is:

Which boundary setting is MOST likely to produce both strong earthquakes and volcanoes?

A student says, “The focus is the same as the epicentre.” Which correction is best?

In a school drill in Jamaica, students practise ‘Drop, Cover, Hold On’. This action is most relevant because Jamaica lies near:

Which sequence best describes how an earthquake occurs on a fault?

A coastline is offset so that a road on one side of a fault is displaced 6 m relative to the other side after a quake. This landform change is best explained by:

Which set of statements is correct? 1. Earthquakes occur on fault lines. 2. Faulting can create scarps and rift valleys. 3. Compression causes rocks to fold. 4. Fold mountains form on divergent plate boundaries.

A region has intense compression, many folds, and very high mountain relief. Which plate-boundary setting most strongly fits this evidence?

A hazard officer in an Eastern Caribbean island is selecting a site for a hospital. Which option best reduces risk from BOTH fault earthquakes and volcanic hazards?

Which pair correctly matches a process with its most direct landform outcome?

A student claims, “Fold mountains and volcanoes are the same thing because both are tall.” Which is the best scientific response?
