MAY EXAM VOLCANO REVIEW

VOLCANOES

By the end of this lesson, you will be able to explain what volcanoes are, how they are formed, and identify their parts.

Multiple Choice

A volcano that will not erupt again, is said to be ...

• extinct

• dormant

• active

Multiple Choice

A volcano that is "sleeping", meaning it will erupt again in the future

• extinct

• dormant

• active

Multiple Choice

A volcano that is erupting

• extinct

• dormant

• active

Multiple Choice

The word, ‘volcano’ comes from the name Vulcan, who was the Roman god of ________

• sea

• land

• fire

Multiple Choice

Most Earthquakes and Volcanoes can be found....

• along the coast of Anarctica

• along plate boundaries

• in the united States

3 Main Types of Volcanoes

Shield

-Non explosive

-Made mostly of thin,
basaltic lava flows

-Large, island forming (Ex.
The Hawaiian Islands)

Composite

-Most common type on Earth

-Has the classic cone shape

-Very explosive - made mostly
of thick, granitic lava flows

-Has alternating layers of lava
flow and pyroclastic material

CInder Cone

-Tend to be smaller

-Can be composite or shield

-Tall, steep sides

-Lava is slightly thicker than the
shield (can explode out cinders)

Multiple Choice

What are Hot Spots?

• Volcanos that are not on a Pate Boundary

• Volcanos erupting from a divergent plate boundary

• The only place at home where my Wifi works

Multiple Choice

If a volcano is not awake, then it is...

• Knocked Out

• Sleep Walking

• Dormant

Label the volcano.

Look at letter C. Which part of the volcano is the letter C pointing at? Is it the magma, crater, or lava?

Multiple Choice

Which part of the volcano was letter C pointing at?

• magma

• crater

• lava

Label the volcano.

Look at letter D. Which part of the volcano is letter D pointing at? Is it the crater, pipe, or magma chamber?

Multiple Choice

Which part of the volcano was letter D pointing at?

• crater

• pipe

• magma chamber

Multiple Choice

What part of a volcano is number 3?

• Vent

• side vent

• crater

• Magma chamber

• Pipe

​What is a volcano?

• ​A volcano is an opening on the surface of Earth and through which gasses and erupted materials pass through.

• ​The erupted material collects to create a cone shaped landform on the surface.

Multiple Choice

What is a volcano?

• An opening in the surface that materials can pass through.

• Mt St Helens

• A place where plates slip and release energy

• Liquid hot magma

Multiple Choice

What are the slopes of a shield volcano like?

• Low and steep

• Chunky and rocky

• Angled and steep

• Wide and flat

What is a volcano?

• It is a mountain made of lava, ash, or other materials from eruptions.

• VOLCANOES CAN COME IN 3 DIFFERENT STATE:

• ACTIVE: It could erupt at any time

• DORMANT: It has not erupted in 10.000 years but could do so again.

• EXTINCT: It has not erupted in the last 10.000 years and will not again.

Multiple Choice

What is a volcano?

• mountain made of lava, ash, or any other materials from eruptions.

• Mountain made of water, nitrogen, or any other raw material

• Mountain made of rocks, surrounded by trees and people.

VOLCANOES

By the end of this lesson, you will be able to explain what volcanoes are, how they are formed, and identify their parts.

Multiple Select

There are three types of volcanoes

• ACTIVE

• DORMANT

• EXTINCT

• AWAKE

• SLEEPY

CONSTRUCTIVE VS DESTRUCTIVE

Volcanic eruptions are constructive in that they add new rock to existing land and form new islands.

Volcanic eruptions can be destructive when an eruption is explosive and changes the landscape of and around the volcano. 

Multiple Choice

VOLCANIC ERUPTIONS CAN BE BOTH CONSTRUCTIVE AND DESTRUCTIVE?

• YES

• NO

PARTS OF A VOLCANO

• MAGMA: It is molten rock under the crust.

• LAVA: It is magma that reaches Earth's surface.

• VENT: It is any opening at the Earth's surface through which magma erupts or volcanic gases are emitted.

• CINDER CONE: It is built from particles and blobs of congealed lava ejected from a single vent.

Multiple Choice

What is lava?

• It is magma that reaches Earth's surface.

• It is molten rock under the crust.

• It is built from particles and blobs of congealed lava ejected from a single vent.

RING OF FIRE

Most volcanoes occur along plate boundaries; an area in the Pacific Ocean where volcanoes are common is called the Ring of Fire.

HAWAII

Hawaii formed over a HOT SPOT as the tectonic plate moves new crust moves over the hot spot, where a new Hawaiian volcano (or island) can form
