Plate Tectonics - Chapter 7 Review

Front

What geological feature is commonly found at convergent plate boundaries?

Back

Volcanic arcs are commonly found at convergent plate boundaries, where two tectonic plates collide.

Front

What zone forms when a less dense plate meets a denser plate?

Back

A subduction zone forms when a less dense tectonic plate meets a denser plate, leading to one plate being forced under the other.

Front

What type of rock would a geologist studying oceanic crust examine?

Back

A geologist studying oceanic crust would examine basalt, which is the primary rock type found in oceanic crust.

Front

What occurs during Earth's magnetic reversals?

Back

During Earth's magnetic reversals, the magnetic field flips, meaning the magnetic north and south poles switch places.

Front

What layer of Earth includes the crust and upper mantle?

Back

The lithosphere includes the Earth's crust and the upper part of the mantle.

Front

What is the theory of plate tectonics?

Back

The theory of plate tectonics explains the movement of the Earth's lithosphere, which is divided into tectonic plates that float on the semi-fluid asthenosphere.

Front

What are the three main types of plate boundaries?

Back

The three main types of plate boundaries are convergent, divergent, and transform boundaries.

Front

What geological activity is associated with divergent plate boundaries?

Back

Divergent plate boundaries are associated with the formation of mid-ocean ridges and rift valleys, where plates move apart.

Front

What is a transform fault?

Back

A transform fault is a type of fault where two tectonic plates slide past each other horizontally, causing earthquakes.

Front

What is the significance of the Ring of Fire?

Back

The Ring of Fire is a major area in the Pacific Ocean basin known for its high levels of seismic activity and volcanic eruptions, due to tectonic plate movements.
