Skill Check 2 Practice (7.10B) Plate Tectonics

Front

What is a convergent plate boundary?

Back

A convergent plate boundary is where two tectonic plates move towards each other, often causing one plate to be forced beneath the other, leading to geological features like mountains, earthquakes, and volcanic activity.

Front

What is a divergent plate boundary?

Back

A divergent plate boundary is where two tectonic plates move apart from each other, leading to the formation of new crust as magma rises to the surface, often creating features like mid-ocean ridges and rift valleys.

Front

What is a transform plate boundary?

Back

A transform plate boundary is where two tectonic plates slide past each other horizontally, causing friction and leading to earthquakes. An example is the San Andreas Fault in California.

Front

What geologic feature is commonly found at divergent boundaries?

Back

Mid-Ocean Ridge, where new oceanic crust is formed as tectonic plates pull apart.

Front

What is the Great Rift Valley an example of?

Back

The Great Rift Valley is an example of a divergent boundary, where tectonic plates are moving apart.

Front

What happens at a convergent boundary?

Back

At a convergent boundary, one tectonic plate is forced under another, leading to subduction, which can create mountains, deep ocean trenches, and volcanic arcs.

Front

What is subduction?

Back

Subduction is the process by which one tectonic plate moves under another plate and sinks into the mantle, often occurring at convergent boundaries.

Front

What type of geological activity is associated with transform boundaries?

Back

Earthquakes are commonly associated with transform boundaries due to the friction between sliding plates.

Front

What is a fault?

Back

A fault is a fracture or zone of fractures between two blocks of rock, which can lead to earthquakes when the blocks move.

Front

What is the Mid-Ocean Ridge?

Back

The Mid-Ocean Ridge is a continuous mountain range that runs along the ocean floor, formed by divergent tectonic plates.
