The video tutorial explains the process of new rock formation at mid-ocean ridges and its role in driving the movement of tectonic plates, which contributes to continental drift. It highlights how the creation of new rock between tectonic plates can separate and push the plates, influencing geological changes.

What geological feature is found on both sides of the mid-ocean ridges?

• Mountains

• Newly formed rock

• Rivers

• Volcanoes

What is created between two tectonic plates at mid-ocean ridges?

• Sand

• New rock

• Water

• Lava

How might the formation of new rock influence continental drift?

• By creating earthquakes

• By forming mountains

• By causing volcanic eruptions

• By driving the movement of tectonic plates

What happens to the tectonic plates as new rock forms?

• They remain stationary

• They merge together

• They separate and move apart

• They sink into the mantle

What is the result of the plates being pushed apart by new rock?

• Development of mountain ranges

• Expansion of ocean basins

• Creation of ocean trenches

• Formation of new continents
