feature within which contains either multiple vents or a
singular vent.

Answer 5

Volcanic Crater

Question 6

is a triangle-shaped hill formed as material from volcanic
eruptions pile up around the volcanic vent or opening in
Earth’s crust.

Answer 6

Volcanic Cone

Question 7

is the weak point in the Earth’s crust where hot magma has
been able to rise from the magma chamber and reach
the surface.

Answer 7

Volcano’s vent

Question 8

is a large pool of liquid rock beneath the surface of the Earth. The location beneath the vent of a volcano where molten rock (magma) is
stored prior to eruption. Also known as a magma storage zone or magma reservoir.

Answer 8

Magma chamber

Question 9

are molten rocks emerging as a liquid onto Earth’s surface. The
temperatures of molten lava range from about 700 to 1,200 °C (1,300 to 2,200 °F).

Answer 9

Lava (Outside), Magma (Inside)

Question 10

What is the place on Earth where volcanoes are mostly commonly found?

Answer 10

PACIFIC RING OF FIRE

Question 11

What are the Types of Volcano Appearance?

Answer 11

Fissure Volcano, Cinder Cone Volcano, Composite Volcano, and Shield Volcano,

Question 12

In geology, It’s a fracture or crack in rock along which there is a distinct separation; are often filled with mineral-bearing materials. On volcanoes, it’s is an elongate fracture or crack at the surface from which lava erupts.

Answer 12

Fissure Volcano

Question 13

also known as pyroclastic cones, are the smallest and the simplest type of volcano with an elevation of 304.8 meters only. They are the world’s most common volcanic landform. These are volcanoes with steep conical hill and bowl-shaped crater.

Answer 13

Cinder Cone Volcano

Question 14

Also known as Stratovolcano are majestic. Is a tall symmetrical shaped volcano with steep sides about 3,047 meters high. The magma composition in this type of volcano commonly contains large amounts of silica, water, and gases

Answer 14

Composite Volcano

Question 15

is a mountain with broad, gently sloping sides
and a nearly circular base. It is formed when layers of lava
accumulate during nonexplosive eruptions. It is also built by
countless outpouring of lave from the summit, wherein lava flows
easily.

Answer 15

Shield Volcano

Question 16

What are the Types of Volcano: Activity

Answer 16

Active Volcanoes, Dormant Volcanoes, and Inactive or Extinct Volcanoes

Question 17

These types of volcanoes are present erupting until today. Some experts consider volcanoes active as long as their inactivity does not reach over 100 years.

Answer 17

Active Volcanoes

Question 18

Most Active Volcano in the Philippines

Answer 18

Mayon Volcano, Albay
Latest Eruption: Early January of 2018

Question 19

Most Active Volcano in the World

Answer 19

Kilauea, Hawai’i
Latest Eruption: Since 1983 to present

Question 20

Volcanoes that have a capacity to erupt later
on. They may have a long intervals between their
last eruption and the latest one. There are volcanoes that has not erupted in almost 10,000 years but are still closely monitored because an eruption can occur at any time.

Answer 20

Dormant Volcanoes

Question 21

Dormant Volcano in the Philippines

Answer 21

Mount Makiling, Calabarzon
Holocene Epoch (12,000 to 11,500
years ago)

Question 22

Dormant Volcano in the World

Answer 22

Mount Fuji, Japan
December 16, 1707

Question 23

Those which have not erupted in human history. These volcanoes still have the potential to erupt.

If a volcano has been inactive for more than
10,000 years, it is considered as ??

Answer 23

Inactive or Extinct Volcanoes

Question 24

Extinct Volcano in the Philippines

Answer 24

Mount Butay, Camiguin
No Historical Eruption Known

Question 25

Extinct Volcano in the World

Answer 25

Ben Nevis, Scotland
No Historical Eruption Known

Question 26

Types of Volcanic Eruption

Answer 26

1. Icelandic Eruption
2. Hawai’ian Eruption
3. Strombolian Eruption
4. Vulcanian Eruption
5. Pelean Eruption
6. Plinian Eruption

Question 27

is characterized by effusions of molten basaltic lava that flow from
long, parallel fissures. Such outpourings often build lava plateaus. (e.g., Fagradalsfjall, Iceland)

Answer 27

Icelandic Eruption

Question 28

similar to the Icelandic variety. In this case, however, fluid lava flows from a volcano’s summit and radial fissures to form shield volcanoes,
which are quite large and have gentle slopes.

Answer 28

Hawai’ian Eruption

Question 29

Involve moderate bursts of expanding gases that eject clots of incandescent lava in cyclical or nearly continuous small
eruptions.

Answer 29

Strombolian Eruption

Question 30

involves moderate explosion of gas laden with volcanic ash, it forms dark, turbulent eruption clouds that expand in convoluted shape.

Answer 30

Vulcanian Eruption

Question 31

is associated with explosive outbursts that generate pyroclastic flows, dense mixtures of hot volcanic fragments and gas. It is named for the destructive eruption of Mount Pelée on the Caribbean island of Martinique in 1902.

Answer 31

Pelean Eruption

Question 32

is an intensely violent kind of volcanic eruption. In this
type of eruption, gases boiling out of gas-rich magma generate enormously and nearly continuous jetting blasts that core out
the vent and rip it apart.
