Quarter 2, Volcanoes

Question 1

are natural wonders that captivate our imagination and shape the landscapes around us.

Answer 1

Volcanoes

Question 2

horseshoe-shaped belt
of intense volcanic activity and frequent earthquakes that encircles the edges of the Pacific Ocean. This region is home to approximately 75% of the world’s active volcanoes and is caused by the movement
and collision of tectonic plates. The Ring of
Fire has a significant impact on Earth’s
surface and the lives of people living in its
vicinity.

Answer 2

Pacific ring of fire

Question 3

are openings in the Earth’s crust
through which molten rock, gas, and other
materials are released from deep within the Earth.

Answer 3

Volcanoes

Question 4

are formed when molten rock called
magma rises to the surface. The magma can come
from the Earth’s matte or from subduction zones
where one tectonic plate slides beneath another.

Answer 4

Volcanoes

Question 5

the volcano.

Answer 5

Magma Chamber

Question 8

Flat rock formation that forms when molten magma cools and solidifies in a crack or
fissure.

Answer 8

Sill

Question 9

The bowl-shaped depression at the top of
the volcano.

Answer 9

crater

Question 15

Generally characterized by non-explosive,
effusive eruptions with the outpouring of
lava flows.

Answer 15

Question 16

its type of eruptions style is Explosive eruptions that eject fragments or
lava and volcanic ash into the air.

Answer 16

Cinder cone volcano

layers of lava flows and volcanic ash.

Answer 18

Composite cone Volcano

Question 19

Can have both explosive eruptiöns and effusive eruptions.

Answer 19

Composite cone volcano

Question 20

Examples of composite cone volcano

Answer 20

• Mount Fuji in Japan
• Mount St. Helens in the United States

Question 21

Types of Volcanoes

Answer 21

(SCC)
Shield Volcano
Cinder cone volcano
Composite cone volcano

Question 22

Volcanic eruptions produce runny lava that
floods the Earth’s surface through long
cracks called fissures, which can be up to 15
miles long.

Answer 22

Icelandic eruption

Question 23

Give an example of Icelandic eruptions

Answer 23

EXAMPLES:
• The Deccan Plateau in India and the
Columbia
• Plateau in the western United States are both large lava plateaus.
• The Deccan Plateau covers 100,000 square miles while the Columbia Plateau is the
largest lava plateau in the world.

Question 24

Volcanic eruptions characterized by
numerous fissures result in large quantities
of hot, thin, and runny lava that flows
rapidly out of the main vent.

Answer 24

Hawaiian Eruptions

Question 25

example of Hawaiian Eruptions

Answer 25

EXAMPLE: • Kilauea, located on the Big Island of Hawaii

Question 26

Short, explosive eruptions shoot thick and pasty lava, steam, and gas into the air, producing little to no lava. The resulting steep-sided cone is called a cinder cone.

Answer 26

Strombolian eruptions

Question 27

Example of Strombolian eruptions

Answer 27

EXAMPLES: • Named after the volcanic island of Stromboli near Italy, Eruptions have been occurring almost continuously for centuries. Due to its frequent eruptions, Stromboli is often referred to as the "Lighthouse of the Mediterranean," as it erupts approximately every 20 minutes.

Question 28

produce high dark clouds of steam, ash, ánd gas, which build a cauliflower-shaped head and a thinner, tree trunk-like base. After this, thick pasty lava is ejected. These eruptions usually build a steep-sided cone that is more symmetrical than a cinder cone.

Answer 28

Vulcanian Eruption

Question 29

Examples of Vulcanian Eruption

Answer 29

EXAMPLES: • Krakatoa (Krakatau) in Indonesia • Katla in Iceland

Question 30

The most common type of volcanic cone, first the volcano will have an explosive eruption that ejects huge amounts of steam, gas, and ash followed by the ejection of lava. They are created from a combination of eruptions forming layers of ash and lava.

Answer 30

Stratovolcanoes Eruption

Question 31

Example of Stratovolcanoes Eruption

Answer 31

EXAMPLES: • Mt. Fuji in Japan • Mt. Etna in Sicily

Question 32

Violent explosion resulting in the collapse of the volcano's summit and the release of a destructive pyroclastic flow. This flow is a rapid and destructive mixture of hot ash, gas, and rocks that annihilates everything in its path.

Answer 32

Pelean Eruption

Question 33

Examples of Pelean Eruption

Answer 33

EXAMPLES: • Mount Pelée in Martinique • Soufrière Hills in Montserrat

Question 34

The most powerful eruption type, with a towering ash cloud reaching up to 50,000 feet (about 10 miles) in height, and extremely dangerous pyroclastic flows.

Answer 34
