Shearing

Stress that pushes rock in opposite directions (like a transform boundary).

seismic waves

The vibrations that move through the ground carrying energy released during an earthquake are called...

fast-moving, hot lava

Describe Pahoehoe.

Shield Volcano

I am a gradually sloping volcano created by low viscosity lava that flows long distances. Who am I?

compound

A substance made of two or more elements that have been chemically combined is a(n)

Tension

The stress that pulls the crust apart.

focus

The point beneath the surface where rocks break and an earthquake starts is the ...

magma

Before lava reaches the surface, this molten material is called...

Cinder Cone Volcano

I am usually pretty quick to be created. I am only made of high viscosity lava, cinders, bombs, and ash. I popped up in a cornfield over night. Who am I?

the crater

The bowl-shaped area around a volcano's vent is called..

Compression

Which type of stress produces revere faults?

Primary Waves

The type of seismic wave that arrive at the surface first and move by compressing and expanding like an accordion are called...

Anticline

Just like my great aunt the hunchback, layers of rock that bend upward into an arch are called...

Composite Volcano

I like to mix things up. I usually alternate lava, then ash, then lava, then more ash. I can keep this up for many years. Who am I?

pipe

The long tube in the ground that connects the magma chamber to the Earth's surface is called the...

Stress

A force that acts on a rock to change its shape or volume

Slower

Compared to P waves, S waves move. (faster), (slower), or (the same speed)

Temperature and Silica content

What two factors (need em' both) determine magma's viscosity?

Volcanoes forming over hot spots

The formation of the Hawaiian Islands is an example of what geological phenomenon? (Not a volcano type)

viscosity

The resistance of a liquid to flowing is called...

Reverse Fault

The type of fault that is formed when compression causes the hanging wall to move over the foot wall.

Focus= below ground Epicenter= surface directly above the focus

What is the main difference between the focus and the epicenter?

P waves

What type of wave can travel through both liquids and solids?

A: Cinder Cone B: Shield C: Composite

Look at these pictures. Name all three volcanoes correctly.

D. Burning

Which of these is NOT a physical property. A. Density B. Hardness C. Melting D. Burning
