BA25 PRESAT - LESSON 109 (TECTONIC PLATES)

What is Plate Tectonics?

• A type of rock formation found in mountains.

• A method for predicting weather patterns.

• The study of ocean currents and tides.

• Plate tectonics is the theory explaining the movement of Earth's lithosphere divided into tectonic plates.

What does the Lithosphere refer to?

• The lithosphere refers to the rigid outer layer of the Earth, including the crust and upper mantle.

• The lithosphere refers to the Earth's atmosphere and weather patterns.

• The lithosphere is the inner layer of the Earth, consisting of molten rock.

• The lithosphere is the liquid layer of the Earth's outer core.

What is the Asthenosphere?

• The asthenosphere is a layer of the atmosphere that affects weather patterns.

• The asthenosphere is the outermost layer of the Earth.

• The asthenosphere is a solid layer of the Earth's crust.

• The asthenosphere is a semi-fluid layer of the Earth's mantle that allows tectonic plates to move.

What happens at a Convergent Boundary?

• Two tectonic plates float on magma, leading to ocean formation.

• Two tectonic plates move apart, causing volcanic activity.

• Two tectonic plates collide, leading to subduction, earthquakes, and mountain formation.

• Tectonic plates slide past each other without interaction.

What occurs at a Divergent Boundary?

• New crust is formed as tectonic plates move apart.

• Crust is destroyed as tectonic plates collide.

• Volcanic eruptions occur due to plate movement.

• Earthquakes are caused by plates sliding past each other.

What characterizes a Transform Boundary?

• Transform boundaries are defined by the formation of new oceanic crust.

• Transform boundaries are characterized by horizontal sliding of tectonic plates.

• Transform boundaries are where tectonic plates collide and create mountains.

• Transform boundaries are characterized by vertical movement of tectonic plates.

What is Subduction?

• Subduction is the process of one tectonic plate being forced beneath another.

• Subduction is the process of tectonic plates moving apart.

• Subduction is the formation of mountains due to tectonic plate collision.

• Subduction occurs when two tectonic plates slide past each other.

What is Seafloor Spreading?

• The movement of tectonic plates towards each other at convergent boundaries.

• The formation of land masses due to volcanic activity on the ocean floor.

• The process of oceanic crust being destroyed at subduction zones.

• Seafloor spreading is the process by which new oceanic crust is formed at mid-ocean ridges as tectonic plates diverge.

What does Continental Drift mean?

• The idea that continents float on a liquid layer beneath them.

• The process of continents merging into one landmass.

• The theory that continents are fixed in place.

• Continental Drift refers to the movement of the Earth's continents relative to each other.

How do tectonic plates interact at boundaries?

• Tectonic plates only converge at boundaries.

• Tectonic plates only move vertically at boundaries.

• Tectonic plates do not interact at all at boundaries.

• Tectonic plates interact at boundaries by diverging, converging, or sliding past each other.
