Plate Tectonics

What is a rift valley?

• A lowland region formed by the convergence of tectonic plates.

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

• A highland region formed by volcanic activity.

• A flat region formed by erosion over time.

What are tectonic plates?

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

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

• Small fragments of the Earth's crust that remain stationary.

• Layers of water that cover the Earth's surface.

What causes volcanic eruptions?

• The movement of tectonic plates, leading to pressure and magma buildup.

• The cooling of lava after an eruption.

• The presence of water in the magma chamber.

• The alignment of the moon and the sun.

What is an earthquake?

• An earthquake is the shaking of the Earth's surface caused by the sudden release of energy in the Earth's lithosphere.

• An earthquake is a weather phenomenon that causes heavy rainfall.

• An earthquake is a geological event that occurs when two tectonic plates slide past each other without any movement.

• An earthquake is a type of volcanic eruption that releases lava and ash.

How do human activities affect tectonic processes?

• Human activities can influence local tectonic processes and potentially trigger earthquakes.

• Human activities have no effect on tectonic processes.

• Human activities only affect the atmosphere, not tectonic processes.

• Human activities can only cause volcanic eruptions, not earthquakes.

What is a hotspot?

• A location where magma from deep within the mantle rises to the surface, often creating volcanoes.

• A place where tectonic plates meet and cause earthquakes.

• A region with high temperatures due to solar radiation.

• An area with frequent rainfall and lush vegetation.

What is the difference between oceanic and continental crust?

• Oceanic crust is thicker and less dense than continental crust.

• Oceanic crust is denser and thinner than continental crust.

• Oceanic crust and continental crust are identical in density and thickness.

• Continental crust is denser and thinner than oceanic crust.

What is the mid-ocean ridge?

• A continuous mountain range formed by divergent tectonic plates under the ocean.

• A type of underwater volcano that erupts lava.

• A deep-sea trench formed by converging tectonic plates.

• A large underwater plateau formed by sediment deposition.

Where do most earthquakes occur?

• Along the edges of tectonic plates.

• In the center of tectonic plates.

• In ocean trenches.

• At the tops of mountains.

What landform is typically found at a convergent boundary between oceanic crust?

• An ocean trench

• A mountain range

• A volcanic island arc

• A rift valley
