Plate Tectonics

What is continental drift?

• The sudden movement of continents during earthquakes.

• The gradual movement of continents across the Earth's surface through geological time.

• The process of continents merging into a supercontinent.

• The shifting of oceanic plates beneath the continents.

What happens at a convergent boundary?

• Plates collide, which can lead to mountain formation, earthquakes, and volcanic activity.

• Plates move apart, creating new crust and leading to volcanic activity.

• Plates slide past each other, causing minimal geological activity.

• Plates remain stationary, resulting in no geological changes.

What is subduction?

• The process where one tectonic plate moves under another and sinks into the mantle.

• The process where tectonic plates slide past each other without significant vertical movement.

• The process of two tectonic plates colliding and forming mountains.

• The process where tectonic plates break apart and create new oceanic crust.

What are tectonic plates?

• Large sections of Earth's crust that move and interact with each other.

• Small fragments of Earth's surface that remain stationary.

• Thin layers of water that cover the Earth's surface.

• Solid rocks that do not change over time.

What is a convergent boundary?

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

• A type of plate boundary where two plates slide past each other.

• A type of plate boundary where two plates move towards each other, often causing one plate to be forced beneath the other.

• A type of plate boundary that does not involve any movement of tectonic plates.

What is a transform boundary?

• A type of plate boundary where two plates collide vertically.

• A type of plate boundary where two plates slide past each other horizontally.

• A type of plate boundary where two plates move apart from each other.

• A type of plate boundary that forms mountains.

What are faults?

• Fractures in Earth's crust where blocks of rock have moved past each other.

• Natural formations created by volcanic activity.

• Areas where tectonic plates are permanently fused together.

• Regions of the Earth that are completely stable and unchanging.

What is sea-floor spreading?

• The process by which new oceanic crust is created at mid-ocean ridges as tectonic plates pull apart.

• The phenomenon where oceanic plates sink into the mantle at subduction zones.

• The movement of tectonic plates due to convection currents in the mantle.

• The formation of new land masses through volcanic activity.

What is an earthquake?

• A sudden release of energy in the Earth's crust that creates seismic waves.

• A continuous shaking of the ground caused by volcanic activity.

• A phenomenon that occurs only underwater and causes tsunamis.

• A type of weather event that results in strong winds and rain.

What is a rift valley?

• A lowland region formed by the divergence of tectonic plates, often found on land.

• A mountainous area formed by the collision of tectonic plates.

• A flat region created by volcanic activity.

• A coastal area formed by the erosion of rocks.
