Plate Tectonics and Volcanoes

What is a hot spot?

• A location where tectonic plates meet and cause earthquakes.

• An area in the mantle from which heat rises as a thermal plume, causing volcanic activity.

• A region with a high concentration of biodiversity.

• A place where meteorological phenomena frequently occur.

What is a shield volcano?

• A steep, conical volcano formed by explosive eruptions.

• A broad, gently sloping volcano formed by the eruption of low-viscosity lava.

• A volcano that primarily erupts ash and tephra.

• A volcano that is always dormant and never erupts.

What is a transform boundary?

• A boundary where two tectonic plates slide past each other.

• A boundary where two tectonic plates collide and create mountains.

• A boundary where tectonic plates move away from each other, forming new crust.

• A boundary that has no movement between tectonic plates.

What is magma?

• Molten rock located beneath the Earth's surface.

• A type of solid rock found on the Earth's surface.

• A gas released during volcanic eruptions.

• A liquid found in oceans and rivers.

What is lava?

• A type of solid rock found in mountains.

• Molten rock that reaches the Earth's surface during a volcanic eruption.

• A gas released during volcanic eruptions.

• A type of mineral found in the Earth's crust.

What is the Earth's outer shell made of?

• Tectonic plates

• Oceanic crust

• Atmosphere

• Mantle

What is a cinder cone volcano?

• A type of volcano that erupts continuously for years.

• The simplest type of volcano where particles and blobs of lava eject from the volcano vent.

• A large volcano that forms from multiple layers of hardened lava and ash.

• A volcano that primarily erupts gas and steam.

What is subduction?

• One plate moves under another one, which can lead to the formation of a volcano.

• Two tectonic plates slide past each other horizontally.

• A process where tectonic plates move apart from each other.

• The collision of two tectonic plates resulting in mountain formation.

What is a composite volcano?

• A type of volcano that is formed from layers of lava and ash.

• A volcano that erupts only once and then becomes inactive.

• A volcano that primarily erupts gas and ash without lava.

• A type of volcano that is formed from a single eruption of lava.

What is a caldera?

• A large volcanic crater formed after the magma chamber collapses.

• A type of volcanic eruption characterized by explosive lava.

• A small volcanic hill formed by the accumulation of volcanic debris.

• A geological formation created by the erosion of a mountain range.
