Plate Boundaries Practice #1

Front

What is a tectonic plate?

Back

A tectonic plate is a massive, irregularly shaped slab of solid rock that makes up the Earth's lithosphere, which is divided into several plates that float on the semi-fluid asthenosphere.

Front

What occurs at a transform plate boundary?

Back

At a transform plate boundary, two tectonic plates slide past each other horizontally, which can cause earthquakes.

Front

What is a divergent boundary?

Back

A divergent boundary is where two tectonic plates move away from each other, leading to the formation of new crust, often at mid-ocean ridges.

What is a convergent boundary?

Back

A convergent boundary is where two tectonic plates collide, which can result in the formation of mountains, earthquakes, or volcanic activity.

What is subduction?

Back

Subduction is the process where one tectonic plate moves under another plate and sinks into the mantle, often leading to volcanic activity.

Front

What are convection currents?

Back

Convection currents are the circular movements of molten rock in the mantle caused by heat from the Earth's core, driving the movement of tectonic plates.

What is the main result of two tectonic plates sliding past one another?

Back

The main result is earthquakes.

Front

What geological feature is formed at mid-ocean ridges?

Back

New oceanic crust is formed at mid-ocean ridges due to the divergence of tectonic plates.

Front

What does the tectonic drift theory explain?

Back

The tectonic drift theory explains that continents move over time due to the movement of tectonic plates.

Front

What happens at a subduction zone?

Back

At a subduction zone, one tectonic plate is forced under another, leading to the formation of deep ocean trenches and volcanic arcs.
