What is formed at convergent, continental-continental plates?
Mid-ocean ridge
Volcanic mountains (volcanic arc)
Mountains
Rift Valley
A process that occurs at mid-ocean ridges, where new oceanic crust is formed through rising magma slowing moving away from the ridge where two ocean plates diverge
ocean trench
sea floor spreading
continental drift
plate tectonics
The theory that the outer rigid layer of the earth (the lithosphere) is divided into a couple of dozen "plates" that move around across the earth's surface

Which of these does not provide evidence that the continents drifted to their present locations?
current weather
landform data
deep-ocean trenches
similar fossils on multiple continents
Which statement explains why tectonic plates move?
Plates move because Earth’s interior is slowly cycling.
Plates move because they are slowly expanding and growing larger.
Plates move because landforms cause them to move in different directions.
Plates move because of the weight of the oceans pressing on parts of Earth’s surface
Which processes are best explained by the theory of plate tectonics?
life cycles of plants
food chains and webs
changes in air pressure
earthquakes and volcanic eruptions
Which of these types of rock would most likely be the youngest?
rock on an oceanic plate that is close to a mid-ocean ridge
rock on an oceanic plate that is farthest from a mid-ocean ridge
rock on a continental plate that is next to a deep ocean trench
rock on a continental plate that is colliding with another continental plate
Which area most likely has the greatest number of fast, large-scale changes?
along seashores
at high elevations
near magnetic poles
near plate boundaries
Which type of change best describes folded mountain belts that sometimes form at plate boundaries?
a slow, large-scale change
a slow, small-scale change
a fast, large-scale change
a slow, small-scale change
Which description is evidence for the theory of plate tectonics but does not suggest that the continents were once connected?
matching rock layers on separate continents
similar land features on separated, present-day continents
the interlocking of present-day coastlines, such as Africa and South America
