Montoya, unit 7 review plate tectonics

Front

What is a divergent plate boundary?

Back

A divergent plate boundary is 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 plate boundary?

Back

A convergent plate boundary is where two tectonic plates collide, leading to the formation of mountains, deep ocean trenches, and volcanic arcs.

Front

What geological feature is formed at a divergent plate boundary?

Back

Mid-ocean ridges are typically formed at divergent plate boundaries.

Front

What geological feature is formed at a convergent plate boundary?

Back

Volcanic arcs are typically formed at convergent plate boundaries.

Front

What is a transform plate boundary?

Back

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

Front

What is the significance of fossils in sedimentary layers?

Back

Fossils in sedimentary layers can indicate the environment in which the layer was formed, such as ocean, forest, or desert.

Front

How do scientists determine the relative age of rock layers?

Back

Scientists use the principle of superposition, where the oldest layers are at the bottom and the youngest are at the top.

Front

What is subduction?

Back

Subduction is the process where one tectonic plate moves under another and sinks into the mantle, often forming deep ocean trenches.

Front

What is the Ring of Fire?

Back

The Ring of Fire is a major area in the Pacific Ocean where many earthquakes and volcanic eruptions occur due to tectonic plate movements.

Front

What is a rift valley?

Back

A rift valley is a lowland region that forms where tectonic plates are moving apart, often filled with water.
