Front

What is the average width increase of the Atlantic Ocean each year?

Back

The Atlantic Ocean gets about 3-5 centimeters wider each year.

Front

What is a pluton in geological terms?

Back

A pluton is a body of intrusive igneous rock that has solidified from magma beneath the Earth's surface.

Front

What geological processes can expose a pluton like Stone Mountain?

Back

A pluton can be exposed by tectonic forces, earthquake action, and erosion.

Front

What natural phenomenon can abruptly change the nature of the soil on Earth’s surface?

Back

A volcanic eruption can abruptly change the nature of the soil.

Front

What is a fault in geological terms?

Back

A fault is a fracture or zone of fractures between two blocks of rock, which can cause earthquakes.

Front

What geological feature is indicated by an aerial photograph showing a large fault?

Back

The geological feature shown is a large fault on Earth’s crust.

Front

Which natural phenomenon is least likely to cause the formation of a large plain valley between two mountains in a short time?

Back

A tornado is least likely to cause the formation of a large plain valley between two mountains in a very short time.

Front

What is the lithosphere?

Back

The lithosphere is the rigid outer layer of the Earth, consisting of the crust and the upper mantle.

Front

What role do tectonic plates play in geological changes?

Back

Tectonic plates are responsible for many geological changes, including earthquakes, volcanic eruptions, and the formation of mountains.

Front

What is erosion and how does it affect geological features?

Back

Erosion is the process by which soil and rock are removed from the Earth's surface by natural processes such as wind or water flow, affecting geological features by reshaping landscapes.
