Plate Tectonics 24

Front

What is Plate Tectonics?

Back

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

Front

What are tectonic plates?

Back

Large sections of the Earth's lithosphere that move and interact with one another, causing geological events such as earthquakes and volcanic eruptions.

Front

What is a divergent boundary?

Back

A type of plate boundary where two tectonic plates move away from each other, often resulting in the formation of new crust, such as mid-ocean ridges.

Front

What is a convergent boundary?

Back

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

Front

What is a transform boundary?

Back

A type of plate boundary where two tectonic plates slide past each other horizontally, often causing earthquakes.

Front

What is subduction?

Back

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

Front

What geological feature is commonly found at divergent boundaries?

Back

Mid-ocean ridges, where new oceanic crust is formed as magma rises to the surface.

Front

What geological feature is commonly associated with convergent boundaries?

Back

Mountain ranges, volcanic arcs, and deep ocean trenches, depending on the type of plates involved.

Front

What is the Ring of Fire?

Back

A major area in the basin of the Pacific Ocean where a large number of earthquakes and volcanic eruptions occur, primarily due to tectonic plate movements.

Front

What evidence did Alfred Wegener use to support his continental drift theory?

Back

Evidence from landforms, fossils, and climate, but NOT evidence from human remains.
