What can we learn form a glassy texture?
A glassy texture indicates that there was no time for crystals to grow and thus the inference is that the magma has cooled very quickly.

Define mineral
What is as inorganic naturally occurring, solids, with a unique combination of elements that are arranged in a specific way.

This volcano has a low rounded profile Gentle slopes of 2-10 degrees
What is shield volcano

What energy changes take place during an earthquake?
What is EPE transforms to KE

On the board, draw an example of a seismograph. Describe how you can tell a powerful Earthquake v. a weaker one.
Draw on the board.

In an igneous rock, when the minerals are so small in size that you cannot see individual crystals
What is fine-grained texture
200
___________is a physical property that is readily observable. Unfortunately, _______ is not always a useful property because some minerals occur in many different _______.
What is color
200
Pyroclastic Material (Fragmented material that has been explosively ejected). Ash and debris accumulates around the vent. Small steep sided cones
What is cinder cone volcano
200
How do P waves move?
What is longitudinal. The motion of the material (like the slinky) and the direction of the wave are the same.
200
How are primary and secondary waves different?(give two ways)
The movement (parallel v. perpendicular) and wave speed.
300
A petrologist might observe a coarse-grained, light-colored rock and from this evidence infer that this rock was formed from a magma that was _______ in composition and that cooled relatively slowly.
What is felsic
300
The appearance of a mineral in reflected light
What is luster
300
Both pyroclastic layers and lava flows Steep sided near summit with decreasing slope
What is composite volcano
300
How do S waves move
What is transverse waves.
300
What do scientists mean when they say the "ring of fire."
The pacific plate crashing into other plates creating zones of subduction and prevalence of earthquakes and volcanoes.
400
igneous rocks that are formed by magmatic activity that has occurred beneath the oceans is _________.
What is mafic
400
Non-metallic minerals may be described as having _____. (name at least 3)
What is glassy, dull, silky, greasy, or brilliant luster.
400
What is evidence of a super volcanic eruption
What are calderas or craters, ashfall composition, fossil records.
400
The point at the Earth‘s surface directly above the focus is called the _________
What is epicenter
400
Why do volcanoes exist on Hawaii when they are no where near the edge of a plate?
What is a hot spot.
500
What creates metamorphic rock?
What is a combination of heat, pressure, and time
500
How does Moh's scale of hardness work?
Moh’s hardness scale goes from 1 to 10. With 1 where the softest mineral is 1 = talc, 2 = gypsum, 3 = calcite, 4 = fluorite, 5 = apatite, 6 = orthoclase, 7 = quartz, 8 = topaz, 9 = corundum, and the hardest mineral is 10 = diamond

How is the model with the soda bottle like a volcanic eruption?
Gas trapped in lava reacts similar to gas trapped in soda. As it's agitated, it simulates an earthquake and releases the gas from the liquid.
500
How are seismic waves used to determine the location of an earthquake?
Earthquake waves also travel out in all directions. The time needed to reach a monitoring device depends on three things: • the distance between the monitor and the quake • the type of wave generated • the material through which the wave travels

What is limestone and how is it different from other types of rocks found on Earth?
It is a metamorphic rock with a composition made up of nothing organic material. Limestone is the rock that metamorphs into marble.
