Semester Exam Review

Front

What is the definition of a convergent boundary?

Back

A convergent boundary is a tectonic plate boundary where two plates collide or come together, often resulting in the formation of mountains or subduction zones.

Front

What geological feature is formed when two continental plates converge?

Back

Folded Mountains are formed when two continental plates converge.

Front

What is a hot spot in geology?

Back

A hot spot is a location where magma from deep within the Earth's mantle rises to the surface, often creating volcanic islands like Hawaii.

Front

How do you determine the relative age of rock layers?

Back

The relative age of rock layers can be determined using the Law of Superposition, which states that in undisturbed layers, the oldest rocks are at the bottom and the youngest are at the top.

Front

What is the significance of the Law of Superposition?

Back

The Law of Superposition is significant because it helps geologists understand the chronological order of geological events and the relative ages of rock layers.

Front

What happens at a divergent boundary?

Back

At a divergent boundary, tectonic plates move apart from each other, leading to the formation of new crust, often seen in mid-ocean ridges.

Front

What is a subduction zone?

Back

A subduction zone is an area where one tectonic plate is being forced under another, often leading to volcanic activity and earthquakes.

Front

What is the difference between a transform boundary and a convergent boundary?

Back

A transform boundary is where two plates slide past each other horizontally, while a convergent boundary is where two plates collide.

Front

What is the process of plate tectonics?

Back

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

Front

What is the result of plate tectonics on Earth's surface?

Back

The movement of tectonic plates results in various geological features such as mountains, earthquakes, and volcanic activity.
