Understanding Tectonic Plate Boundaries

What is a hot spot in geological terms?

• A tectonic plate boundary where two plates move toward each other.

• An anomalously hot, stationary point below the lithosphere where melting of the mantle and crust generates volcanism.

• A crack in a body of rock that the rock can move along.

• A tectonic plate boundary where two plates move away from each other.

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

• Convergent Boundary

• Divergent Boundary

• Transform Boundary

• Subduction Zone

What is the lithosphere primarily composed of?

• Mostly water and air.

• Mostly rocks, the crust, and outer mantle.

• Mostly gases and minerals.

• Mostly molten lava and magma.

Which of the following best describes a convergent boundary?

• A tectonic plate boundary where two plates move away from each other.

• A tectonic plate boundary where two plates move toward each other, causing collisions and subduction zones.

• A tectonic plate boundary where plates slide past each other horizontally.

• A stationary point below the lithosphere causing volcanism.

What geological process involves the sinking of an oceanic plate beneath a plate of lesser density, often resulting in volcanic activity?

• Subduction

• Divergence

• Faulting

• Hot Spot Formation

Which of the following best describes a divergent boundary?

• A tectonic plate boundary where two plates move toward each other.

• A tectonic plate boundary where two plates move away from each other.

• A tectonic plate boundary where plates slide past each other horizontally.

• A crack in a body of rock that the rock can move along.

What is a fault in geological terms?

• A tectonic plate boundary where two plates move toward each other.

• A tectonic plate boundary where two plates move away from each other.

• A crack in a body of rock that the rock can move along.

• A stationary point below the lithosphere causing volcanism.

Which of the following describes a supervolcano?

• A volcano that forms at a transform boundary.

• A volcano capable of ejecting more than 1 cubic kilometer of matter in an eruption.

• A small volcano that forms at a divergent boundary.

• A volcano that erupts less than 1 cubic kilometer of matter.

Which geological feature is characterized by the formation of long mountain chains with a central rift valley, typically found at divergent boundaries?

• Rift Valley

• Mid-Ocean Ridge

• Transform Boundary

• Convergent Boundary

What is the term for a tectonic valley formed by extensional stress, leading to fracturing and the creation of normal faults?

• Rift Valley

• Mid-Ocean Ridge

• Hot Spot

• Supervolcano
