Plate Tectonics Concepts and Questions

The video tutorial explains plate tectonics using an orange as a model for Earth's structure. It covers the differences between continental and oceanic crusts, the movement of tectonic plates, and the types of plate boundaries: divergent, convergent, and transform. The tutorial also discusses how these movements create geological features like mountains, trenches, and earthquakes.

What part of the Earth does the skin of the orange represent in the plate tectonics model?

• The outer core

• The crust

• The mantle

• The inner core

Which type of Earth's crust is thicker and less dense?

• Neither, they vary

• Continental crust

• Both are the same

• Oceanic crust

How many major plates is the Earth's crust divided into?

• 20

• 15

• 12

• 10

What is the primary cause of plate movements according to the video?

• Solar radiation

• Hot mantle convection cells

• Ocean tides

• Wind currents

What type of plate boundary involves plates moving apart and creating new land?

• Convergent

• Transform

• Static

• Divergent

Which type of plate boundary is associated with the creation of mountains?

• Convergent

• None of the above

• Divergent

• Transform

What geological feature is formed when one oceanic plate sinks beneath another?

• Ridge

• Trench

• Mountain

• Volcano

What happens at transform boundaries?

• Plates remain stationary

• Plates collide

• Plates slide past each other

• Plates move apart

Which type of plate collision is likely to result in the formation of a trench?

• Continent-oceanic

• Continent-continent

• None of the above

• Ocean-ocean

Why are earthquakes common near transform boundaries?

• Due to ocean currents

• Because plates collide

• Because plates slide past each other

• Due to volcanic activity
