Plate Boundaries
Two blate boundaries that move towards each other.
What are convergent plate boundaries?
A theory explaining the structure of the earth's crust and many associated phenomena as resulting from the interaction of rigid lithospheric plates that move slowly over the underlying mantle.
What is plate tectonics?
The tool that scientists use to map the ocean floor.
What are sonars?
A mountain or hill that's typically conical, having a crater or vent through which lava, rock fragments, hot vapor, and gas are being or have been erupted from the earth's crust.
What is a volcano?
The physical disintegration and chemical decomposition of earth's materials at or near the earth's surface.
What is weathering?
The plate boundaries that move away from each other.
What are divergent plate boundaries?
The gradual movement of the continents across the earth's surface through geological time.
What is continental drift?
A line on a map joining points of equal height above and below sea level.
What are contour lines?
The shaking of the surface of the earth, resulting from the sudden release of energy in the earth's lithosphere that creates seismic waves.
What is an earthquake?
Any of the various weathering that causes physical disintegration of exposed without any change in the chemical composition of the rock.
What is mechanical weathering?
Two plate boundaries that move towards each other
What are divergent plate boundaries?
The formation of new areas of oceanic crust, which occurs through the upwelling of magma at mid-ocean ridges and its subsequent outward movement on either side.
What is seafloor spreading?
A map using contour lines.
What is a contour map?
A gap or space made by cleaving or splitting.
What is a rift?
The erosion or disintegration of rocks, building materials, caused by chemical reactions.
What is chemical weathering?
The landform that would most likely occur at a convergent plate boundary.
What are mountain Ranges?
A long seismically active submarine ridge system situated in the middle of an ocean basin.
What is a mid-ocean ridge?
An elastic wave in the earth produced by an earthquake or other means.
What are seismic waves?
What formed the boundaries between earth tectonic plates.
What is a fault?
Any resource, such as wood or solar energy, that can or will be replenished naturally in the course of time.
What is a natural resource?
Describe what would most likely occur when two plates converge.
What is Subduction?
The process by which the collision of the earth's crustal plates results in one plate to subduct under the other.
What is a subduction zone?
A region in a longitudinal wave where particles are the closest together.
What is compression?
A fold of rock layers that slope upward on both sides of a common low point.
What is a syncline?
A resource of economic value that cannot be readily replaced by natural means on a level equal to its consumption.
What is a Non-renewable resource?
