Answer 11

Shield volcanoes

Question 12

Classification of volcanoes.

Answer 12

Shield, Composite, Cinder cone.

Question 13

Eruptions of _______ are mild and can occur several times.

Answer 13

Shield.

Question 14

Volcano that is rich in silica and has thick magma which results in gasses being trapped inside.

Answer 14

Composite volcanoes

Question 15

Eruptions from ______ volcanoes can be flowing lava or explosions. The explosive eruptions comes from the trapped gasses and produce cinders and ash.

Answer 15

Composite

Question 16

Volcanoes that have much steeper slopes

Answer 16

Composite volcanoes

Question 17

Volcanoes that are usually only active for a short period of time and then become dormant (inactive).

Answer 17

Cinder cone

Question 18

The magma inside a _______ volcano has large amounts of gas trapped in it.

Answer 18

Cinder cone volcanoes

Question 19

The large amounts of hot ash and lava thrown out of the vent fall to the ground forming the cone shapes cinder cone volcanoes have. True or false?

Answer 19

True.

Question 20

Establish probabilities of eruption, style and location for individual volcanoes.

Answer 20

Long term prediction

Question 21

Based on the recognition of a pattern of events prior to previous eruptions.

Answer 21

Short-Term prediction

Question 22

Recognition of changes in the land surface due to building pressure

Answer 22

Surface tilting.

Question 23

Generated as the magma moves up the feeder conduit to the vent.

Answer 23

Earthquakes.

Question 24

The more earthquakes the further the ____ has moved

Answer 24

Magma

Question 25

Magnitudes are generally more than 5 M. True or false?

Answer 25

False. (Less)

Question 26

The six eruption types are:

Answer 26

Hawaiian, Icelandic, Strombolian, Vulcanian, Pelean, and plinian.

Question 27

The lava that flows from _____ and _____ eruptions are very hot, very thin, runny lava.

Answer 27

Icelandic, Hawaiian.

Question 28

______ eruptions usually produce little or no lava

Answer 28

Strombolian

Question 29

_____ and _____ eruptions are the most dangerous and explosive of the eruption types

Answer 29

Pelean, Plinian

Question 30

Named after the island of vulcano off the coast of Italy.

Answer 30

Vulcanian eruptions

Question 31

What does it mean when a volcano is dormant?

Answer 31

It has not erupted in our recorded history.

Question 32

What is the role of seismic data on the prediction of volcanic eruptions?

Answer 32

Track magma’s movements in the volcanoes

Question 33

What is the term used to represent the opening of the volcano where magma comes out?

Answer 33

Vent.

Question 34

What is the most important sign of an impending volcanic eruption which is also referred as seismic activity?

Answer 34

volcanic tremor

Question 35

For sources of energy, coal has the highest CO2 emissions. True or false

Answer 35

True

Question 36

Waves that do not travel through liquids.

Answer 36

S waves

Question 37

_____ travel through solids and liquids

Answer 37

P waves.

Question 38

Outermost layer on earth

Answer 38

Crust

Question 39

Layer after the crust.

Answer 39

Mantle

Question 40

How does latitude affect climate?

Answer 40

When the area is farther from the equator, the air temperature is lower resulting in a cold ​climate. When the place is closer to the equator, the air temperature is higher which results in a warm climate.​

Question 41

Why are places with high temperature found at the equator?

Answer 41

Due to the tilting of the earth’s axis

Question 42

Why do some areas that are far from bodies of water have extreme climates?

Answer 42

Because there no bodies of water that will moderate the change in temperature in the location.
