fault
100
rock changed in composition or texture by heat and pressure
Metamorphic rock
100
What is the name of the proposed giant landmass made up of all seven continents?
Pangea
100
Which type of plate boundary to two plate move AWAY from each other?
Divergent
100
Which type of rock would be found as it sinks towards the mantle at a subduction zone?
Metamorphic
200
Which vocab words describes: the scientific theory that the lithosphere is made up of rigid pieces, called tectonic plates, that move across Earth’s surface
plate tectonics
200
rock formed from the deposition of dissolved materials, rock fragments, or the remains of organisms
sedimentary rock
200
Which scientist proposed the idea that the continents were once all connected as Pangea, but drifted to their current positions?
Alfred Wegner
200
Which type of plate boundary exists between the Pacific Plate and North American Plate?
Transform
200
Which type of rock would be found at the mid-ocean ridge?
Igneous
300
Which vocab word describes: the hypothesis that the continents slowly drifted to their current positions after having been part of a single, giant landmass that broke apart
Continental drift
300
rock formed from the cooling and solidification of magma on or below Earth’s surface
igneous rock
300
What is the name of the theory that the continents were once connected in one supercontinent (Pangea) and drifted to their current positions?
Continental drift
300
What is being depicted below, in which two plates move towards each other, and one plate sinks below the other?
Subduction
300
Which type of rocks would a volcano be made from?
Igneous
400
Which vocab word describes: the process by which a collision between two tectonic plates forces the denser plate under the less dense plate
subduction
400
the continuous set of processes by which rock can change from one type to another; a model of how the flow of energy drives the cycling of rock material in the geosphere
the rock cycle
400
What two pieces of evidence helped support Wegner's continental drift hypothesis?
1. The same fossils found on different continents
2. The shape of the continents look like puzzle pieces
400
Which process is being depicted below, in which sea floor is created?
Sea floor spreading
400
Which type of igneous rocks form outside the earth's surface and do NOT have crystals?
EXTRUSIVE
500
Which vocab word describes: the process by which the rocks on either side of the mid-ocean ridge slowly pull away from each other, allowing molten rock to rise, solidify, and form new seafloor
sea floor spreading
500
a substance that is made of crystals and has a specific chemical composition and geometric shape
mineral
500
What was the name of the geologist who mapped the location of fossils and found the Glossopteris in non-tropical locations?
Hint: NOT Alfred Wegener
Edward Seuss
500
What is the NAME of the location where sea floor spreading takes place?
The mid-ocean ridge
(mid-atlantic ridge acceptable)
500
Which type of igneous rocks form within the earth's surface and have large crystals?
INTRUSIVE
