37 Multiple choice questions
- The upward vertical movement of the ground surface, as occurs during mountain building.
push, pull, or shear that a material feels when subjected to a force;
formally, the force applied per unit area over which the force acts.
- The change in shape of an object in response to deformation (i.e., as a result of the application of a stress).
- Layering formed as a consequence of the alignment of mineral grains, or of compositional banding in a metamorphic rock.
- A gently dipping reverse fault; the hanging-wall block moves up the slope of the fault.
- A linear range of mountains.
angle at which a layer tilts, relative to horizontal; the angle is
measured in an imaginary vertical plane that trends perpendicular to the
- A change in the shape, position, or orientation of a material, by bending, breaking, or flowing.
the context of folds, this is the imaginary plane that contains the
hinge lines of successive layers in the fold; it is the surface that
divides a fold into its two separate limbs.
- The bending and flowing of a material (without cracking and breaking) subjected to stress.
- A stress that pulls on a material and could lead to stretching.
- A fold in the land surface whose shape resembles that of a carpet draped over a stair step.
- A trough-shaped fold whose limbs dip toward the hinge.
condition that exists when the buoyancy force pushing lithosphere up
equals the gravitational force pulling lithosphere down.
- A seam of minerals that forms when dissolved ions carried by water solutions precipitate in cracks.
- The compass trend of an imaginary horizontal line on a plane.
- A small step on the ground surface where one side of a fault has moved vertically with respect to the other.
- Naturally formed cracks in rocks.
- A stress that moves one part of a material sideways past another part.
- The portion of a fold where curvature is greatest.
- A long-lived block of durable continental crust commonly found in the stable interior of a continent.
- The process in which mountains begin to collapse under their own weight and spread out laterally.
- The side of a fold, showing less curvature than at the hinge.
- A fold or depression shaped like a right-side-up bowl.
- The cracking and fracturing of a material subjected to stress.
- A bend or wrinkle of rock layers or foliation; folds form as a consequence of ductile deformation.
- The amount of movement or slip across a fault plane.
- A steeply dipping fault on which the hanging-wall block slides up.
satellite system people can use to measure rates of movement of the
Earth's crust relative to one another, or simply to locate their
position on the Earth's surface.
- Force per unit area, or the ÒpushÓ acting on a material in cases where the push is the same in all directions.
- A push or squeezing felt by a body.
- A fold with an arch-like shape in which the limbs dip away from the hinge.
- A fault in which the hanging-wall block moves down the slope of the fault.
- A mountain-building event.
fault in which one block slides horizontally past another (and
therefore parallel to the strike line), so there is no relative vertical
- A fracture on which one body of rock slides past another.
- Folded or arched layers with the shape of an overturned bowl.
