Tectonic Plates and Their Dynamics

The video explains plate tectonics, a concept describing the movement of Earth's lithosphere. It covers the types of tectonic plates, their movement, and the resulting geological phenomena like earthquakes and mountain formation. The video also discusses the historical formation of continents and modern methods for tracking plate movements using GPS technology.

What is the primary cause of the Earth's surface moving slowly?

• Wind erosion

• Volcanic eruptions

• Plate tectonics

• Ocean currents

What is the lithosphere composed of?

• The entire mantle

• Only the Earth's crust

• The Earth's crust and part of the upper mantle

• The Earth's core

What layer lies beneath the tectonic plates and causes them to move?

• The asthenosphere

• The hydrosphere

• The biosphere

• The atmosphere

How many major tectonic plates are there on Earth?

• Twelve
