This video is a comprehensive review of plate tectonics, covering the theory, types of plate boundaries, and related geological phenomena. It explains convergent, divergent, and transform boundaries, as well as hot spots and the law of superposition. The video also guides students on using Earth Science reference tables and includes practice questions to reinforce learning.

What is the lithosphere composed of?

• Gases

• Magma

• Water

• Rocks

What happens at a convergent plate boundary?

• Plates slide past each other

• Plates remain stationary

• Plates move towards each other

• Plates move apart

What geological feature is formed at a divergent boundary?

• Mid-oceanic ridges

• Mountain ranges

• Deep ocean trenches

• Volcanic islands

What is a hot spot?

• A stationary magma source beneath the Earth's crust

• A volcanic region on the ocean floor

• A high-pressure zone in the Earth's core

• A region of intense heat in the mantle

What does the law of superposition state?

• Older rocks are found on top of younger ones

• Younger rocks are always on the bottom

• The deepest layer of rock is the youngest

• The oldest layer of rock is always on the bottom

How can sea creatures end up fossilized on mountain tops?

• Through human activity

• By being carried by animals

• Due to land uplift

• Through volcanic eruptions

What does the outer core of the Earth consist of?

• Iron and nickel in a solid state

• Iron and nickel in a liquid state

• Granite and basalt

• Magma and lava

What feature is associated with a complex or uncertain plate boundary?

• Galapagos Hot Spot

• East African Rift

• Southwest Indian Ridge

• Mariana Trench

What drives the movement of tectonic plates?

• Gravitational pull from the moon

• Convection currents in the asthenosphere

• Rotation of the Earth

• Magnetic fields of the Earth

What is indicated by the presence of mirror-image magnetic patterns on either side of the mid-ocean ridge?

• The Earth's magnetic field reverses periodically

• The ocean floor is static and unchanging

• The Earth's magnetic field has never changed

• Plate tectonics is a flawed theory
