Iceland's Volcanic Activity and Geography

The video explores Iceland's unique geological features, highlighting its origins as a volcanic island formed 20 million years ago. It discusses the Mid-Atlantic Ridge, where tectonic plates move apart, causing volcanic activity. Iceland's geothermal fields and active volcanoes are also examined, showcasing the island's dynamic geological landscape.

What geological event led to the formation of Iceland as the world's largest volcanic island?

• A massive earthquake

• A glacial movement

• An underwater volcanic eruption

• A meteor impact

Which natural features characterize Iceland's extreme environments?

• Cool waters and geothermal fields

• Rainforests and rivers

• Mountains and valleys

• Deserts and sand dunes

What is the significance of Iceland's location on the Mid-Atlantic Ridge?

• It is the largest desert in the world

• It is the only place where the ridge is visible above water

• It is the highest point on Earth

• It is the coldest place on the planet

How do the North American and Eurasian plates affect Iceland's geography?

• They cause the island to sink

• They make the island rotate

• They create cracks and expand the island

• They cause the island to shrink

At what rate do the North American and Eurasian plates move apart?

• At the speed of light

• At the rate of hair growth

• At the rate fingernails grow

• At the speed of sound

What fuels the volcanic activity in Iceland?

• The movement of tectonic plates

• The melting of glaciers

• The rotation of the Earth

• The flow of ocean currents

How often does a volcanic event occur in Iceland?

• Every decade
