Tectonic Plate Boundaries

What is the role of tectonic plates in earthquakes?

• Tectonic plates can cause earthquakes when they move suddenly along faults at transform boundaries.

• Tectonic plates are responsible for the formation of mountains and valleys only.

• Tectonic plates have no impact on seismic activity.

• Tectonic plates only affect ocean currents and weather patterns.

How do tectonic plates affect the Earth's surface?

• They cause weather patterns to change.

• They shape the Earth's surface through processes like mountain building, volcanic activity, and the creation of ocean basins.

• They have no effect on the Earth's surface.

• They only affect the ocean floors.

What is a divergent boundary?

• A boundary where two tectonic plates move towards each other, causing earthquakes.

• A boundary where two tectonic plates slide past each other, leading to friction.

• A boundary where two tectonic plates move away from each other, leading to the formation of new crust, often seen at mid-ocean ridges.

• A boundary where tectonic plates remain stationary, resulting in no geological activity.

What happens when two oceanic plates collide?

• A trench is formed, and one plate may be subducted beneath the other.

• The plates push upwards to form mountains.

• The plates slide past each other without any significant geological activity.

• The plates break apart and create new oceanic crust.

What is the significance of the Ring of Fire?

• It is a major area in the basin of the Pacific Ocean where many earthquakes and volcanic eruptions occur, due to tectonic plate boundaries.

• It is a region known for its abundant marine life and coral reefs.

• It is a historical trade route used by ancient civilizations.

• It is a popular tourist destination for its beautiful beaches.

What is a tectonic plate?

• A massive, irregularly shaped slab of solid rock that makes up the Earth's lithosphere, including the crust and upper mantle.

• A thin layer of gas surrounding the Earth that protects it from solar radiation.

• A large body of water that separates continents and affects climate.

• A type of mineral found in the Earth's crust that is used in construction.

What is a volcanic island arc?

• A chain of volcanic islands formed at a convergent boundary between two oceanic plates.

• A series of mountains formed by tectonic uplift.

• A type of island formed by erosion and sediment deposition.

• A linear arrangement of coral reefs in shallow waters.

What is the difference between oceanic and continental plates?

• Oceanic plates are thicker and less dense, primarily composed of granite, while continental plates are thinner and denser, primarily composed of basalt.

• Oceanic plates are thinner and denser, primarily composed of basalt, while continental plates are thicker and less dense, primarily composed of granite.

• Oceanic plates are composed of sandstone, while continental plates are composed of limestone.

• Oceanic plates are found only in the Arctic, while continental plates are found in tropical regions.

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, characterized by steep walls and a central block that has dropped down.

• A highland region formed by volcanic activity.

• A flat region formed by sediment deposition over time.

What is a transform boundary?

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

• A boundary where two tectonic plates slide past each other horizontally, leading to earthquakes.

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

• A boundary that has no tectonic activity and remains stable.
