Tectonic Plates and Geological Features

The video covers plate tectonics, explaining Earth's layers, the lithosphere, and types of plate boundaries: divergent, convergent, and transform. It discusses convection cycles, hotspots, and how subduction at convergent boundaries leads to geological formations like mountains and volcanoes. The video also highlights how understanding plate boundaries can help predict earthquakes and volcanic activity, with a focus on the Ring of Fire.

What is the lithosphere?

• A semi-solid rock layer above the mantle

• A sea of magma beneath the Earth's surface

• A thin layer of rock floating on magma

• A dense mass of solid nickel and iron

Which layer of Earth is responsible for driving the movement of tectonic plates?

• The mantle

• The crust

• The asthenosphere

• The core

What geological feature is formed at divergent plate boundaries?

• Trenches

• Coastal mountain ranges

• Island arcs

• Mid-oceanic ridges

What occurs when two tectonic plates collide at a convergent boundary?

• They move away from each other

• One plate is forced beneath the other

• They slide past each other

• They remain stationary

Which type of plate boundary is most associated with earthquakes?

• Subduction

• Transform fault

• Convergent

• Divergent

What is the Ring of Fire?

• A region of frequent earthquakes

• A hotspot in the Atlantic Ocean

• A pattern of volcanoes around the Pacific plate

• A series of mid-oceanic ridges

What is the primary cause of volcanic activity at convergent plate boundaries?

• Seafloor spreading

• Subduction of oceanic plates

• Transform fault movement

• Divergence of continental plates

How do transform fault boundaries differ from other types of plate boundaries?

• They result in the formation of island arcs

• They cause the creation of Rift Valleys

• They involve plates moving alongside each other

• They create mid-oceanic ridges

What is a hotspot in the context of plate tectonics?

• A region of intense earthquake activity

• An area where magma rises through the lithosphere

• A location where plates are moving apart

• A zone of frequent subduction

Which of the following is a result of convection cycles in the mantle?

• The occurrence of tsunamis

• The formation of the Himalayas

• The creation of the Andes mountain range

• The movement of tectonic plates
