Properties of Magma
100

Stress that pulls and stretches rock is called

Tension


100

T/F 

Stress adds energy to rocks

TRUE ALL DAY LONG

100

A huge hole left behind when a volcano collapses is a 

Caldera

100

The viscosity of magma depends on two things, what are they?

Silica Content and Temperature

100

What is an example of a chemical property?

Anything that involves chemistry, being able to burn, being able to bond/react with other substances

200

What type of Fault is caused by compression?

Reverse

200

A creep meter does what?

Measures how far the sides of a fault have moved in opposite directions

200

When a volcano erupts quietly, what forms?

Shield Volcano

200

What is a mass of rock formed when a large body of magma cools inside the crust?

Batholith

200

What is an example of a physical property?

Anything you can physically see/touch/smell.


Color, Odor, Rough/Smooth

300

Seismic Waves that come first are called what?

P Waves

300

Which scale compares one Earthquake to another?

Richter

300

A wide gently sloping mountain is a 

Shield Volcano

300

Very Hot magma produces lava called

Pahoehoe

300

What is viscosity?

A fluid's resistance to flow...


Honey, Oil, Water, all different viscosities

400

What are the three types of seismic waves?

P, S, and Surface Waves

400

Which scale is based on the amount of damage an Earthquake does?

Mercalli

400

What two types of volcanoes erupt explosively?

Cinder-Cone, Composite

400

How a volcano erupts depends on what?

The amount of silica present

400

When magma reaches the surface it is called?

Lava

500
What are the three types of stresses, boundaries, and faults?

Convergent=Compression=Reverse

Divergent=Tension=Normal

Transform=Shearing=Strike-Slip

500

Why is it difficult to predict when an Earthquake might occur?

Just because plates have moved does not mean there will be an Earthquake..

Stress adds energy but sometimes does not result in an Earthquake

500

What type of volcanoes are tall, cone-shaped mountains in which layers of lava alternate with layers of ash?

Composite

500

Hot spots can occur...

Far from plate boundaries....


YELLOWSTONE SUPER VOLCANO

500
