Question 6

Is there more or less gas in non explosive magma?

Answer 6

Less

Question 7

What do non explosive eruptions do.

Answer 7

Create a “calm” flow of magma that flows out of the earths surface.

Question 8

What kind of volcanoes do nonexplosive eruptions create?

Answer 8

Shield

Composite(stratavolcanoes)

Question 9

Is there more or less gas in explosive magma? What does that do.

Answer 9

More. More pressure. Water and silica go up

Question 10

What do explosive eruptions create.

Answer 10

Pyroclastic Flows

Question 11

What are pyroclastic flows? Is it more or less dangerous than non explosive eruptions.

Answer 11

Enormous amounts of hot ash, gases, dust from volcanoes. Much more dangerous

Answer 12

Cinder cone volcanoes(moderate explosion by volcanoes)

Composite

Hotspots are volcanically active places far from plate boundaries. Hawaii

Question 20

Is a crater bigger or smaller than a cladera?

Answer 20

Smaller

Question 21

What are two ways to predict eruptions. Explain them

Answer 21

Measure surface temp and gas emissions- by measuring the surface temp you may be able to tell if a volcanoes is about to erupt. The temp may change dramatically. You can also measure the gas emissions to find when a volcanoes will erupt. If the gas coming out of a volcanoes changes, it could be about to erupt.

Use a tiltameter to measure the volcanoes side- if you use a tiltmeter to measure the side of a volcano, you may be able to predict and volcanoes. If the side of the volcanoes suddenly swells, there may be magma coming up.
