Semester exam review 2024

Front

What is the theory of continental drift?

Back

The theory that continents have moved over geological time and were once joined together in a single landmass.

Front

What evidence supports the theory of continental drift?

Back

Fit of the continents, matching fossil evidence, and similar rock formations.

Front

What causes day and night on Earth?

Back

The rotation of the Earth on its axis, causing different parts to face the sun or be in shadow.

Front

What is the tilt of the Earth's axis and how does it affect seasons?

Back

The Earth's axis is tilted at about 23.5 degrees, causing different seasons as different hemispheres receive varying amounts of sunlight.

Front

What are the major tectonic plates on Earth?

Back

Large sections of the Earth's lithosphere that move and interact at their boundaries, causing geological activity.

Front

What are the three types of plate boundaries?

Back

Divergent, convergent, and transform boundaries.

Front

What happens at divergent boundaries?

Back

Plates move apart, leading to the formation of new crust, often seen at mid-ocean ridges.

Front

What happens at convergent boundaries?

Back

Plates collide, which can cause mountains to form or one plate to be subducted beneath another.

Front

What happens at transform boundaries?

Back

Plates slide past each other, which can cause earthquakes.

Front

What is a cold front?

Back

A boundary where a cold air mass replaces a warm air mass, often bringing precipitation.
