Plate Tectonics

The video explains the theory of plate tectonics, detailing how Earth's crust is divided into plates that move due to convection currents in the mantle. It covers different types of plate boundaries, such as divergent, convergent, and transform, and their geological effects, including the formation of oceans, mountains, and earthquakes. The video also discusses the historical movement of continents, the creation of the Atlantic Ocean, and the concept of hot spots like Hawaii. It concludes with a look at Earth's geological history, including the breakup of Pangaea.

What causes the movement of the Earth's plates according to the theory of plate tectonics?

• Wind and ocean currents

• Magnetic fields of the Earth

• Convection currents in the mantle

• Gravitational pull from the moon

What geological feature is formed at a divergent boundary?

• Volcanic islands

• Ocean trenches

• Rift valleys

• Mountain chains

What happens at a convergent boundary?

• Plates remain stationary

• Plates slide past each other

• Plates move towards each other

• Plates move apart

Which famous fault is an example of a transform boundary?

• East African Rift

• Himalayan Fault

• Mid-Atlantic Ridge

• San Andreas Fault

What is a hot spot in geological terms?

• A place where oceanic crust is created

• A region of high volcanic activity at plate boundaries

• A stationary area of volcanic activity in the mantle

• A location where two plates collide
