Which of the following is TRUE about the movement of continents?
Continents do not move
Continents move separately from the plates
Continents move with their plate
Continents moved in the past but are not moving now
Which of the following represents how three of Earth’s plates fit together?
continents but not ocean basins
ocean basins but not continents
both ocean basins and continents
neither ocean basins and continents
Where does seafloor spreading occur?
at ocean trenches
at mid-ocean ridges
at the San Andreas fault
at the edge of an ocean basin
Which of the following describes a reasonable movement of Earth’s plates?
The plates do not move.
The plates move 1 - 10 centimeters (0.4 - 4 inches) per year.
The plates move 1 - 10 meters (3 - 30 feet) per year.
The plates move 1 - 10 kilometers (0.6 - 6 miles) per year.
What does plate tectonic theory predict about the distribution of volcanoes and earthquakes?
They should occur primarily in deep ocean basins
They should only occur along continental margins
They should occur primarily along plate boundaries
They should be evenly distributed throughout the Earth
What happens when an oceanic part of one plate collides with the continental part of another plate?
The continental part is subducted beneath the oceanic part
The collision of the plates stopped their motions completely
The oceanic part is subducted beneath the continental part
The oceanic part is not subducted but was broken into small pieces
Seafloor spreading provides evidence of which of the following Earth processes?
erosion of coastlines
weathering of mountains
movement of tectonic plates
formation of sedimentary rocks
Which of the following are part of Earth’s tectonic plates?
continents but not ocean basins
ocean basins but not continents
both ocean basins and continents
neither ocean basins and continents
Which of the following statements best explains why earthquakes occur more frequently in California than in Pennsylvania?
California is located on a continental plate, but Pennsylvania is not
The rock under California is soft, but the rock under Pennsylvania is hard
California is located on the boundary of two tectonic plates, but Pennsylvania is not
The rock found in California is igneous, but the rock found in Pennsylvania is
sedimentary
During sea floor spreading, long volcanic ridges form because ...
less dense, hot magma moves to the surface.
underwater earthquakes lift the sea floor into long ridge.
sediments are deposited where the floor spreads, building ridges.
ocean water pushes down on the surrounding sea floor, pushing up ridges.
