Plate Tectonics

What causes the movement of tectonic plates?

• Convection currents in the Asthenosphere.

• Gravitational pull from the Moon.

• Wind patterns in the atmosphere.

• Ocean currents in the Pacific Ocean.

What does the theory of continental drift state?

• The continents were once joined in a super-continent and have moved over time.

• The continents are fixed in their positions and do not move.

• The continents were formed by volcanic activity alone.

• The continents are slowly sinking into the ocean.

What is a transform boundary?

• A boundary where two tectonic plates collide, forming mountains.

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

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

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

How are mountains formed?

• Mountains are created when two continental plates collide.

• Mountains are formed by volcanic activity.

• Mountains are the result of erosion over time.

• Mountains are created by the movement of tectonic plates in the ocean.

What is the lithosphere?

• The lithosphere is the rigid outer layer of the Earth, consisting of the crust and upper mantle.

• The lithosphere is the liquid layer of the Earth located beneath the crust.

• The lithosphere is the gaseous layer surrounding the Earth.

• The lithosphere is the inner core of the Earth made of molten iron.

What evidence supported Wegener’s theory of continental drift?

• Plate tectonics and seismic activity.

• Rock, fossil, and climate data.

• Oceanic trench formations.

• Magnetic field reversals.

What happens at a subduction zone?

• The denser oceanic crust is subducting under the less dense continental crust.

• The continental crust is rising above the oceanic crust.

• Both oceanic and continental crusts are moving apart.

• The oceanic crust is melting into the mantle.

What role do convection currents play in plate tectonics?

• Convection currents in the mantle drive the movement of tectonic plates.

• Convection currents cause earthquakes and volcanic eruptions.

• Convection currents are responsible for the formation of mountains.

• Convection currents have no effect on tectonic plate movement.

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 is a convergent boundary?

• A boundary where two tectonic plates collide, often forming mountains or causing subduction.

• A boundary where two tectonic plates move apart, creating new crust.

• A boundary where tectonic plates slide past each other without creating or destroying crust.

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