Hot spot

The video explains how rocks melt to form magma, which rises and causes volcanic activity on Earth's surface. It discusses how hotspots remain stationary while tectonic plates move, creating trails of volcanoes. The Hawaiian Islands are an example of land formed over a hotspot.

What process leads to the creation of magma beneath the Earth's surface?

• Melting of rocks

• Freezing of lava

• Erosion of soil

• Condensation of water vapor

How does magma contribute to volcanic activity?

• It absorbs atmospheric gases

• It forms new tectonic plates

• It rises in columns and erupts

• It cools down the Earth's surface

What is the role of hotspots in volcanic formation?

• They move with tectonic plates

• They cool down magma

• They remain fixed and create volcano trails

• They cause earthquakes

What happens to tectonic plates as they move over hotspots?

• They form new continents

• They dissolve into magma

• They create a series of volcanoes

• They become stationary

How were the Hawaiian Islands formed?

• By ocean currents

• By a series of earthquakes

• By a fixed hotspot

• By a moving tectonic plate
