The global distribution of earthquakes and volcanoes

Where do we find volcanoes and earthquakes?

• A) In the sky

• B) In the ocean

• C) On tectonic plate boundaries

• D) In the desert

Answer explanation

Volcanoes and earthquakes are commonly found on tectonic plate boundaries, making option C the correct choice.

What is the relationship between tectonic plate boundaries and volcanoes?

• D) Volcanoes occur in the middle of continents

• C) Volcanoes occur on plate margins

• A) There is no relationship

• B) Volcanoes occur randomly

Answer explanation

Volcanoes occur on plate margins, where tectonic plates meet and interact, leading to volcanic activity.

How many active volcanoes are found on the edge of the Pacific Ocean?

• B) A few

• D) Too many to count

• A) None

• C) Many

Answer explanation

The correct answer is C) Many because the edge of the Pacific Ocean is known as the 'Ring of Fire' and is home to many active volcanoes.

What causes volcanic eruptions?

• C) Movement of tectonic plates

• B) Earth's rotation

• A) Rainfall

• D) Solar flares

Answer explanation

Volcanic eruptions are caused by the movement of tectonic plates, making option C the correct choice.

Where do the majority of earthquakes occur?

• C) In the desert

• B) Along tectonic plate boundaries

• A) In the mountains

• D) In the middle of continents

Answer explanation

The majority of earthquakes occur along tectonic plate boundaries, making option B the correct choice.

What is the main cause of tectonic hazards?

• A) Human activities

• B) Movement of tectonic plates

• C) Global warming

• D) Volcanic eruptions

Answer explanation

The main cause of tectonic hazards is the movement of tectonic plates, which leads to earthquakes and volcanic eruptions.

How many earthquakes occur every year?

• C) Over 20,000

• D) Exactly 10,000

• A) Less than 100

• B) Around 1,000

Answer explanation

The correct answer is C) Over 20,000 because a large number of earthquakes occur every year worldwide.

Where are the majority of earthquakes found?

• C) Africa and Australia

• B) Asia and the west coast of North and South America

• D) Middle of the Pacific Ocean

• A) Europe

Answer explanation

The majority of earthquakes are found in Asia and the west coast of North and South America, making option B the correct choice.

What is the relationship between tectonic plate boundaries and earthquakes?

• A) No relationship

• D) Earthquakes occur in the middle of continents

• B) Earthquakes occur randomly

• C) Majority of earthquakes occur along tectonic plate boundaries

Answer explanation

The correct answer is C) Majority of earthquakes occur along tectonic plate boundaries, as tectonic plate movements and interactions at the boundaries cause stress and result in earthquakes.

Where are hot spots found?

• D) Not usually found on tectonic plate boundaries

• C) In the desert

• B) In the middle of continents

• A) On tectonic plate boundaries

Answer explanation

Hot spots are not usually found on tectonic plate boundaries, so the correct answer is D.
