Earth's layers and plate tectonics

What geological feature is formed at a convergent boundary?

• Volcanoes

• Mid-ocean ridges

• Mountains, such as the Himalayan Mountains

• Plateaus

What is the relationship between volcanoes and plate boundaries?

• Most volcanoes are found at plate boundaries, where tectonic activity allows magma to reach the surface.

• Volcanoes are primarily located in the center of tectonic plates, away from boundaries.

• Volcanoes only occur in oceanic regions, far from any plate boundaries.

• Plate boundaries have no influence on volcanic activity.

What is the asthenosphere?

• A solid layer of the Earth's crust that supports tectonic plates.

• A semi-fluid layer of the mantle beneath the lithosphere that allows tectonic plates to move.

• The outermost layer of the Earth that is composed of water and ice.

• A layer of the Earth's atmosphere that protects the planet from solar radiation.

What evidence supports the theory of plate tectonics?

• The fit of continental coastlines, fossil distribution, and the location of earthquakes and volcanoes.

• The presence of ancient pyramids in South America.

• The discovery of new species in isolated islands.

• The alignment of mountain ranges across continents.

What are rift valleys?

• Low-lying areas formed by the movement of tectonic plates apart, often leading to volcanic activity.

• High mountain ranges formed by the collision of tectonic plates.

• Flat plains created by the erosion of sediment over time.

• Deep ocean trenches formed by subduction of tectonic plates.

What is the role of the mantle in plate tectonics?

• The mantle provides the heat and convection currents that drive the movement of tectonic plates.

• The mantle acts as a solid barrier preventing plate movement.

• The mantle is responsible for the formation of oceanic trenches.

• The mantle contains the Earth's magnetic field.

How do earthquakes relate to plate tectonics?

• Earthquakes are caused by volcanic eruptions.

• Earthquakes occur when stress builds up at plate boundaries and is released, causing the ground to shake.

• Earthquakes happen randomly and are not related to plate movements.

• Earthquakes are only caused by human activities like mining.

What is the difference between the crust and the mantle?

• The crust is the thin, outermost layer of the Earth, while the mantle is a thicker layer beneath the crust composed of semi-solid rock.

• The crust is a thick layer of molten rock, while the mantle is a thin layer of solid rock above it.

• The crust is the layer of the Earth that contains water, while the mantle is composed entirely of gas.

• The crust is the innermost layer of the Earth, while the mantle is the outermost layer.

What is a convergent plate boundary?

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

• A location where two tectonic plates collide, often causing one plate to be forced beneath the other.

• An area where tectonic plates slide past one another without significant interaction.

• A boundary where tectonic plates are stationary and do not interact.

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.

• A boundary where tectonic plates move away from each other and create new crust.

• A boundary that is characterized by volcanic activity and earthquakes.
