-
What kind of faults are there?
Transform (sliding), normal, and reverse fault.
-
What are composite/strato volcanoes?
Volcanoes that are the result of a series of explosive volcanic eruptions, these volcanoes are more conically shaped and formed along plate boundaries
-
What occurs when the top of a composite volcano gets sheared off?
A glowing gas cloud appears.
-
What occurs when silica is incorporated in magma?
The magma becomes viscous at a lower melting point.
-
What is/ are the characteristics of a shield volcano?
A shield volcano is built from effusive eruptions. It is gently sloped with a shape similar in outline to a shield of armor lying face up on the ground.
-
Define cinder cone.
Cinder cones are small, and made of ash and cinder
-
Define caldera.
A caldera is a large, basin-shaped depression that forms when summit material on a volcanic mountain collapses inward after an eruption
-
Why is Hawaii moving?
The island chain was formed by a hot spot, and it moves away from the hot spot towards the northwest so new islands can form
-
Why do the Hawaiian islands get progressively smaller as you move north?
Weathering makes them smaller, and no forces are creating new landmasses.
-
What is a sea spout?
An island that doesn't make it to the surface.
-
What kinds of faults are there?
Transform, normal, reverse, and overthrust faults.
-
What is the deepest place on Earth?
The Mariana Trench.
-
What are forshocks? How often do they occur?
Forshocks are small quakes before a big earthquake. They only occur 5% of the time.
-
Where is the epicenter of an earthquake located?
The area at the surface directly above the focus.
-
What are the three factors that determine the damage done by an earthquake?
Magnitude, distance from center, and bedrocks.
-
How do Palm Oases form?
They form near subduction zones along faults that have a groundwater table. Water surfaces along the fault.
-
Where does the San Andreas fault run to and from.
From No Cal to So Cal and almost to Mexico.
-
What are P waves?
Pressure waves. They cause compression and rarefaction (?) waves.
-
What are S waves?
Surface waves. They cause undulations.
-
Do P waves or S waves cause more damage? Which ones will you feel first?
S waves cause more damage. You feel P waves first.
-
How do long waves undulate?
Laterally.
-
What is an anticline?
The area long the ridge of a fold where layers slipe downward away from the axis.
-
What is a syncline?
The area in the trough of the fold where layers slope downward toward the axis.
