Plate Boundaries 2024

Front

What is a mid-ocean ridge?

Back

A mid-ocean ridge is an underwater mountain range formed by plate tectonics, where two tectonic plates are moving apart, allowing magma to rise and create new oceanic crust.

Front

What is the significance of plate boundaries?

Back

Plate boundaries are regions where two tectonic plates meet, and they are significant because they are the sites of geological activity such as earthquakes, volcanic eruptions, and mountain building.

Front

Define convergent boundary.

Back

A convergent boundary is a type of plate boundary where two tectonic plates move towards each other, often resulting in one plate being forced beneath another, leading to subduction.

Front

What is a divergent boundary?

Back

A divergent boundary is a type of plate boundary where two tectonic plates move away from each other, leading to the formation of new crust as magma rises to the surface.

Front

Explain transform boundary.

Back

A transform boundary is a type of plate boundary where two tectonic plates slide past each other horizontally, causing friction and leading to earthquakes.

Front

What are convection currents in the mantle?

Back

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

Front

How do you calculate the rate of plate movement?

Back

Front

What is subduction?

Back

Subduction is the process by which one tectonic plate moves under another and sinks into the mantle, often creating deep ocean trenches and volcanic arcs.

Front

Define hotspot in geology.

Back

A hotspot is a location on the Earth's surface that has experienced active volcanism for a long period, often due to a plume of hot material rising from deep within the mantle.

Front

What is the relationship between plate tectonics and earthquakes?

Back

Earthquakes are often caused by the movement of tectonic plates at their boundaries, where stress builds up and is released suddenly.
