Explain how seafloor spreading contributes to the movement of tectonic plates.

• It causes the plates to shrink.

• It creates new oceanic crust that pushes the plates.

• It pulls the plates together.

• It has no effect on the movement of the plates.

• Rock erosion

• Climate patterns

• Ocean currents

Describe the process of continental drift proposed by Alfred Wegener.

• The continents are stationary and do not move.

• The continents slowly drift across the Earth's surface over geological time.

• The continents are formed by volcanic activity.

• The continents are eroded by wind and water.

What is the main driving force behind the movement of tectonic plates?

• Earth's rotation

• Gravitational attraction of the moon

• Convection currents in the mantle

• Ocean tides

How does the concept of seafloor spreading support the theory of plate tectonics?

• It shows that the ocean floor is static.

• It demonstrates that new crust is formed at ocean ridges and moves outward.

• It proves that the continents are shrinking.

• It indicates that the ocean floor is older than the continents.

• Pangea was a supercontinent that broke apart due to continental drift.

• Pangea was formed by volcanic activity.

• Pangea was a myth and never existed.
