Exploring the Theory of Plate Tectonics

The video explores the position of North America today compared to 250 million years ago, highlighting its drift from other continents. It introduces the theory of plate tectonics, explaining how Earth's surface is composed of moving plates. These movements have significantly shaped the planet, forming mountains, volcanoes, trenches, and causing earthquakes.

How did the position of North America change over the past 250 million years?

• It rotated 180 degrees.

• It drifted away from other continents.

• It moved closer to the equator.

• It remained in the same position.

What theory explains the movement of Earth's continents?

• Theory of Evolution

• Theory of Relativity

• Theory of Plate Tectonics

• Theory of Gravity

According to the theory of plate tectonics, what is Earth's surface made of?

• Floating islands

• Liquid magma

• Several rigid plates

• A single solid mass

Which of the following is NOT a result of tectonic plate interactions?

• Deep sea trenches

• Deserts

• Volcanoes

• Mountain ranges

What natural events are caused by the movement of tectonic plates?

• Earthquakes

• Floods

• Hurricanes

• Tornadoes
