What is the Theory of Continental Drift?

Back

The Theory of Continental Drift states that the continents were once joined in a super-continent and have moved apart over time.

Front

What is Pangea?

Back

Pangea is the name given to the super-continent that existed when all continents were joined together.

Front

What evidence supports the Theory of Continental Drift?

Back

The similarity of fossils found on different continents supports the Theory of Continental Drift.

Front

What are lithospheric plates?

Back

Lithospheric plates are large sections of the Earth's crust that move and interact with each other.

Front

What is plate tectonics?

Back

Plate tectonics is the scientific theory that explains the movement of the Earth's lithospheric plates.

Front

What is the significance of fossil similarity in different continents?

Back

Fossil similarity indicates that continents were once connected, supporting the Theory of Continental Drift.

Front

What is the main idea of the Theory of Plate Tectonics?

Back

The main idea is that the Earth's surface is divided into plates that move due to convection currents in the mantle.

Front

What is seafloor spreading?

Back

Seafloor spreading is the process by which new oceanic crust is created at mid-ocean ridges as tectonic plates move apart.

Front

How do convection currents affect plate movement?

Back

Convection currents in the mantle cause the lithospheric plates to move, leading to geological activity.

Front

What is the relationship between continental drift and climate?

Back

Continental drift can affect climate by changing ocean currents and the distribution of land and water.
