Question 1

pyroclastic material

Answer 1

all rock fragments created by explosive eruptions

Question 1

Mountains can also be created through _____________________.

Answer 1

Volcanism

Question 1

destroy everything in their path, covering everything with molten rock and lighting many things on fire. However they are slow enough for people to get out of the way of , travelling at speeds of 1-30 km/hr based on lava thickness and slope steepness.

Answer 1

lava flows

Question 1

A mixture of water and rock fragments that speed down the side of a volcano pulverizing everything in its path.

Answer 1

lahur

Question 2

A mix of hot gases and pyroclastic materials. They move very fast and can destroy everything in the path.

Answer 2

pyroclastic flows

Question 2

A mixture of pyroclastic rock fragments thrown in the air by an eruption

Answer 2

tephra

Question 4

volcano

Answer 4

A mountain that forms when molten rock cools on earth’s surface

Question 5

pyroclastic flows

Answer 5

A mix of hot gases and pyroclastic materials. They move very fast and can destroy everything in the path.

Question 5

small volcanos made entirely of pyroclastic materials. They have steep slopes with narrow bases and erode away easily. Sunset Crater near Flagstaff is one

Answer 5

cinder cone volcanoes

Question 6

cinder cone volcanoes

Answer 6

small volcanos made entirely of pyroclastic materials. They have steep slopes with narrow bases and erode away easily. Sunset Crater near Flagstaff is one

Question 7

explosive eruption

Answer 7

clouds of debris and gas shoot out of the volcano. Lava is blown into the air where it hardens as it flies. Ash from these can stay in the upper atmosphere for years.

Question 8

Landslides

Answer 8

Often caused by volcanoes, they often destroy part of the volcano itself and can bury villages.

Question 9

Made from layers of both lava and pyroclastic materials. They have broad bases and tend to become steeper towards the summit. They are very common and examples include Japan’s Fuji and Mount Vesuvius

Answer 9

composite volcanoes (strato volcanoes)

Question 10

composite volcanoes (strato volcanoes)

Answer 10

Made from layers of both lava and pyroclastic materials. They have broad bases and tend to become steeper towards the summit. They are very common and examples include Japan’s Fuji and Mount Vesuvius

Question 12

clouds of debris and gas shoot out of the volcano. Lava is blown into the air where it hardens as it flies. Ash from these can stay in the upper atmosphere for years.

Answer 12

explosive eruption

Question 13

all rock fragments created by explosive eruptions

Answer 13

pyroclastic material

Question 15

hot spot

Answer 15

volcanoes can also be formed from magma that comes from deep within the Earth. A ____ _____ is the location where a column of rising magma, called a mantle plume intersects the Earth’s surface.

Question 16

Often caused by volcanoes, they often destroy part of the volcano itself and can bury villages.

Answer 16

Landslides

Question 17

When a fault is under stress the rock will bend and deform until enough stress is applied to cause the energy to be ____________.

Answer 17

Released

Question 18

can form when thin lava runs out of many cracks in the ground, or fissures and spreads evenly over the ground

Answer 18

lava plateau

Question 19

built out of layers of lava from multiple nonexplosive eruptions. They tend to spread out over a wide area and have gently sloping sides. They can also be enormous. Hawaii’s Mauna Kea is one which when measured from the ocean floor to the tip is the tallest mountain on Earth.

Answer 19

shield volcano

Question 21

An island formed by the sinking of a previous island and its fringing coral reef.

Answer 21

Atoll

Question 22

lava plateau

Answer 22

can form when thin lava runs out of many cracks in the ground, or fissures and spreads evenly over the ground
