What is a conclusion of a scientific question that CAN`T be proven?
Theory
100
What is a Divergent Boundary?
When two plates move apart from each other
100
What is the Elastic Rebound?
When plates straighten after being put under stess, this causes seismic waves.
100
Describe each type of mafic lava.
Pahoehoe- cools slowly, ropy texture Aa- cools quickly, jagged texture
100
List the Rock Cycle
Magma -> Crystallization -> Igneous Rock -> Weathering and Erosion -> Sediment -> Cementation and Compaction -> Sedimentary Rock -> Heat and Pressure -> Metamorphic Rock -> Melt -> Magma
200
What is a prediction based of of logic and and obsevation?
Hypothesis
200
What is a Convergent Boundary?
When two plates move apart from each other
200
What is the focus?
The point under the surface of the earth where plates fault
200
What is the difference between felsic and mafic lava?
Felsic lava is light colored, thick lava, that is usually found in continental crust. (explosive) Mafic lava is dark colored, think, and usually found in the ocean crust. (non-exlosive)
200
What are igneous rocks?
Rocks that are formed through cooling and crystalization
300
What is a variable?
The part of an experiment that changes.
300
What is a Transform Boundary?
When two plates slide past each other
300
What is an epicenter?
The point on the surface of the earth where directly above the focus
300
What is a caldera?
A feature produced when an emptied magma chamber causes a volcano to collapse.
300
What are metamorphic rocks?
Rocks formed from intense heat and pressure underground
400
What is experimentation?
Testing a question
400
What is a Subduction Zone?
A region where one plate moves underneath another
400
What is the difference between P and S Waves?
P waves, primary ways, are the first waves to arrive from an earthquake and S waves, secondary waves, are the second waves to arrive from an earthquake.
400
Name the different pyroclastic material from smallest to biggest.
Volcanic Dust, Volcanic Ash, Lapilli, Volcano Bombs
400
Foliated texture
Minerals that are compressed and flattened so they look like stripes
500
What is a conclusion to a scientific question that CAN be proven?
Scientific Law
500
What is a Convection Current?
The movement of heat through the asthenosphere which causes plates above to move (What causes plate tectonics)
500
What is the Mercalli System?
The amount of damage caused by an earthquake
500
What is a crater?
A feature produced when the vent of a volcano is blown apart during an eruption.
500
What`s the difference between intrusive and extrusive rocks.
Extrusive- rocks that formed from under the ground, volcanoes Intrusive- rocks that formed underground
