Lesson 3 Shaping Earth's Surface Review

Front

Name and describe the three types of mountains and how they form.

Back

Fold mountains, fault-block mountains, and volcanic mountains. Fold mountains form by the collision of tectonic plates, fault-block mountains form by the movement of large crustal blocks, and volcanic mountains form from volcanic activity.

Front

Volcanoes happen at these two types of plate boundaries.

Back

Convergent and divergent plate boundaries.

Front

Describe what a tsunami is and how it causes damage.

Back

A tsunami is a series of ocean waves caused by underwater earthquakes or volcanic eruptions. It causes damage by flooding coastal areas and destroying structures.

Front

Describe what happens at an oceanic-to-oceanic crust convergent boundary.

Back

One oceanic plate subducts beneath another, forming a trench and potentially leading to volcanic activity.

Front

Definition of a volcano.

Back

A volcano is an opening in the Earth's surface through which molten rock, ash, and gases are ejected.

Front

Definition of a subduction zone.

Back

A subduction zone is a region where one tectonic plate moves under another, sinking into the mantle.

Front

Definition of a volcanic arc.

Back

A volcanic arc is a chain of volcanoes formed above a subducting plate.

Front

Definition of an earthquake.

Back

An earthquake is the shaking of the Earth's surface caused by the sudden release of energy in the Earth's crust.

Front

Explain the process of sea-floor spreading.

Back

Sea-floor spreading occurs at mid-ocean ridges where new oceanic crust is formed through volcanic activity and then gradually moves away from the ridge.

Front

Describe the formation of a mid-ocean ridge.

Back

A mid-ocean ridge is formed by divergent tectonic plates moving apart, allowing magma to rise from the mantle and solidify, creating new oceanic crust.
