Unraveling the Layers of Earth and Plate Tectonics

The video explains the Earth's lithosphere, which is divided into tectonic plates that move and interact through processes like collision, subduction, and sliding past each other. It describes the Earth's layers, focusing on the mantle and lithosphere, and compares continental and oceanic lithosphere. The video details the types of plate boundaries—transform, divergent, and convergent—and their associated geological activities, such as earthquakes and mountain formation. It also covers subduction zones, island arcs, and the occurrence of interplate earthquakes.

What is the process called when massive plates of the lithosphere move and interact with each other?

• Seafloor spreading

• Plate tectonics

• Continental drift

• Volcanic activity

Which layer of the Earth is located between the crust and the core?

• Asthenosphere

• Lithosphere

• Mantle

• Outer core

What is the characteristic of the asthenosphere compared to the lithospheric mantle?

• It is cooler and more rigid

• It is hotter and more ductile

• It is thicker and denser

• It is composed of granite

What is the average thickness of continental crust?

• 8 kilometers

• 150 kilometers

• 200 kilometers

• 40 kilometers

Which type of lithosphere is denser and forms the ocean floor?

• Tectonic lithosphere

• Oceanic lithosphere

• Asthenospheric lithosphere

• Continental lithosphere

What type of plate boundary involves plates moving horizontally against each other?

• Divergent boundary

• Convergent boundary

• Transform boundary

• Subduction zone

Where do most earthquakes occur?

• On or near convergent boundaries

• In the middle of tectonic plates

• In the asthenosphere

• At the Earth's core

What geological feature is formed when an oceanic plate subducts beneath another oceanic plate?

• Transform fault

• Rift valley

• Mountain range

• Island arc

What happens when two continental plates collide?

• One plate subducts beneath the other

• They form a transform boundary

• They create mountains and plateaus

• They form an ocean trench

What is the term for earthquakes that occur within the interior of tectonic plates?

• Subduction earthquakes

• Intraplate earthquakes

• Transform earthquakes

• Divergent earthquakes
