Answer 2

crater

Question 3

A channel or pipe conveying liquid materials such as magma.

Answer 3

conduit

Question 4

Is a hot fluid or semi-fluid material below or within the earth’s crust
that is usually made from molten rocks inside the earth.

Answer 4

magma

Question 5

The rock or magma is expelled from a volcano during an eruption.
Formation of volcano

Answer 5

Lava

Question 6

It is dependent on the plates which form the top layer on the mantle

Answer 6

formation by subduction

Question 7

A region of high volcanic activity not located at any plate boundary

Answer 7

hotspot

Question 8

are currently active if it is erupting lava, releasing gas or generating seismic activity. An active volcano is labelled dormant if it has not erupted for a long time but could erupt again in the future

Answer 8

active volcanoes

Question 9

are volcanoes that are not currently active, but may be either dormant or extinct or of otherwise uncertain inactive volcanic status.

Answer 9

inactive volcanoes

Question 10

It has a broad, gently sloping landform built by many layers of low-viscous lava flows which cannot be filed up into steep mounds.

Answer 10

Shield volcanoes

Question 11

A type of volcano that has a steep conical hill formed above a vent that is composed mostly of basalt

Answer 11

cinder cone volcanoes

Question 12

Is one constructed of alternating layers of pyroclastic materials and solidified lava flows.
with high silica content

Answer 12

composite volcanoes

Question 13

It is a volcanic crater that is formed when a part of the wall of the crater collapses following an explosive eruption.
usually triggered by the emptying of the margins chamber beneath the volcano as the result of a large volcanic eruption

Answer 13

caldereta joke caldera

Question 14

it is a stream-driven eruption as the hot rocks come in contact with water
A Steam- Blast eruptions as a hot rock comes in contact with water.

Answer 14

phreatic eruption

Question 15

IT IS A VIOLENT ERUPTION DUE TO THE CONTACT BETWEEN WATER AND MAGMA RESULTING IN A VIOLENT FINE ASH ERUPTION

Answer 15

Phreatomagmatic eruption

Question 16

It is a period of weak to violent eruption characterized by fountain lava.

Answer 16

Strombolian

Question 17

It is characterized by a tall eruption that reaches up to 20 km high with pyroclastic flow and ashfall tephra

Answer 17

vulcanian eruption

Question 18

It is an excessively explosive type of eruption of gas and pyroclastics.

Answer 18

plinian eruption

Question 19

Volcano eruptions whichtake place beneath the surface of water. These occur at constructive margins, subduction zones and within tectonic plates due to hotspots. This eruption style is far more prevalent than subaerial activity

Answer 19

Answer 20

landslides
earthquake

Question 21

A type of volcanic eruption in terms of activity which are characterized by a gas-driven explosion that propels magma and tephra.

Answer 21

explosive eruptions

Question 22

are characterized by outpourings of lava on to the ground

Answer 22

effusive eruptions

Question 23

the energy generated and stored on the earth that can be extracted in either a heat pump system or hot dry conversion

Answer 23

Geothermal energy

Question 24

70% comes from the decay of radioactive nuclei with long half lives that are embedded within the Earth.

Answer 24

Sources of earth’s internal energy

Question 25

As the name implies these are reservoirs of hot underground water. There is a large amount of them in the US, but they are more suited for space heating than for electricity production.

Answer 25

hot water reservoirs

Question 26

a hole dug into the ground can cause steam to come to the surface. This type of resource is rare in the US.

Answer 26

natural steam reservoirs

Question 27

DIRECT USES OF GEOTHERMAL ENERGY IS APPROPRIATE FOR SOURCES BELOW 1500C

Answer 27

space heating air conditioning industrial processes drying Greenhouses Agriculture hot water resorts and pools melting snow

Question 28

HOW DIRECT USES WORK

Answer 28

Direct Sources function by sending water down a well to be heated by the Earth’s warmth. Then a heat pump is used to take the heat from the underground water to the substance that heats the house. Then after the water it is cooled is injected back into the Earth.
