Thinnest, outermost layer above mantle
What is the crust?
The names of the two scales we use to measure earthquakes.
What is the Richter Scale and the Modified Mercalli Intensity Scale?
This volcano has a broad, low profile and lava does NOT erupt violently from it.
What is a shield volcano?
Has one solid layer and one liquid layer.
What is the core?
Contains most of Earth's mass
What is the mantle?
Layer between asthenosphere and outer core.
What is the mesosphere?
These types of waves are the fastest and can move through solids, liquids, and gases.
What are P-waves?
The three things that contribute to how violently a volcano erupts...
What are gas, silica, and water?
The three major types of folds near plate boundaries.
What are syncline folds, anticline folds, and monocline folds?
Thin flexible crust that wrinkles as lava moves underneath it.
What is pahoehoe?
Soft molten layer on which tectonic plates move
What is the asthenosphere?
This type of deformation states that rock stays folded after the pressure is gone.
What is plastic deformation?
The 4 major types of lava...
What is Aa, pahoehoe, blocky lava, and pillow lava?
Rocks slide past each other horizontally due to shear stress.
What are strike-slip faults?
Two pieces of evidence for plate tectonics theory.
What is the Genesis account of the Flood and fossil evidence?
What is the focus?
The amount that each level on the Richter Scale increases by...
The 4 main types of pyroclastic material.
What are volcanic bombs, lapilli, volcanic ash, and volcanic blocks?
The types of convergent boundaries.
What are...
1. Continental - Continental
2. Oceanic - Continental
3. Oceanic - Oceanic
These can be produced by oceanic-oceanic convergent boundaries.
What are island arcs?
An instrument that records vibrations in the ground
What is a seismograph?
Earthquakes that happen here can be very strong because of the built up pressure.
What are convergent boundaries?
The 4 ways scientists can estimate when a volcano is about to erupt.
What is...
1. Monitoring earthquakes
2. Monitoring gases
3. Changes in slope (volcano swells)
4. Increase in surface temperature
These can be produced by divergent boundaries.
What are mid-ocean ridges and new sea floor crust?
The percentage of volcanoes found at convergent boundaries.
What is 80%?
