Definitions
Define deformation
The process by which rock changes shape when under stress.
True or False. In a strike-slip fault, the fault blocks move past each other vertically.
False. The move past each other horizontally.
True or false. Folded mountains form when melted rock erupts onto Earth's surface.
False. That is volcanic mountains
True or false. A volcano is any place where gas, ash or melted rock come out of the ocean.
False. A volcano is any place where gas, ash or melted rock come out of the ground.
True or false. A hot spot is a location where a column of extremely cold mantle rock rises through the asthenosphere.
False. Extremely hot mantle rock rises
Define folding.
Folding --the bending of rock layers due to stress
True or false. In a normal fault, the hanging wall moves down relative to the footwall.
True
True or false. Fault-block mountains form when tension makes the lithosphere break into normal faults.
True
True or false. Melted rock, or magma, is more dense than solid rock, so it rises toward the surface.
False. It is less dense.
False
Define volcano.
The hanging wall move up relative to the footwall.
What are the three kinds of mountains? (100 points per type)
Folded, volcanic, fault-block
What is a vent?
An opening of a volcano
True or false. The movement of tectonic plates places stress on rocks.
True
A block of lithosphere that consists of the crust and the rigid outermost part of the mantle
Name two common types of folds.
Synclines and anticlines
A process that can cause land to rise can also contribute to mountain building.
What makes lava different than magma?
Lava is magma that reached the Earth's surface
What is Ms. Ross' favorite color? (It is a very specific color ---- be specific)
North Carolina Blue or a light blue will be accepted
Define shear stress.
Stress that occurs when forces act in parallel but opposite directions, pushing parts of a solid in opposite directions.
What is the difference between synclines and anticlines folds?
Synclines --- youngest layers are found at the core of the fold. Anticline--oldest layers are found at the core of the fold.
True or false. Most of Earth's active volcanoes are concentrated around Western New York and Niagara Falls.
False. They are concentrated around the edge of the Pacific
What is a tectonic plate?
Giant sections of lithosphere on Earth's surface.
True or false. Ms. Ross' two favorite subjects growing up were Math and Science.
False. My two favorite subjects were Math and Gym. (Lunch is not a subject!)
