A plate boundary where two plates move away from each other is called a
Subduction Boundary
Plates slide past each other at _______ boundaries.
divergent
convergent
transform
collision
Convergent plate movement can result in which of the following geologic landforms?
faults AND volcanoes
earthquakes AND valleys
volcanoes AND mountains
rift valleys AND ocean ridges
Oceanic ridges form from
plates colliding together
plates shifting away from each other
plates moving over a hotspot
Which of the following forms where one plate slides under another plate?
hotspot zone
collision zone
Observe this diagram of a plate boundary. Which statement BEST describes why this plate is subducting?
Oceanic crust is naturally denser than continental crust.
New ocean floor is generally located at divergent plate boundaries.
Continental crust is heavier and sinks as a result.
Subduction creates volcanic mountains and islands.
The Himalayan mountain range and Tibetan plateau have formed as a result of the collision between the Indian Plate and Eurasian Plate which began 50 million years ago and continues today. Because both these landmasses have about the same rock density, one plate could not be subducted under the other. Which type of collision resulted in the formation of the Himalayas?
Continental-Oceanic
Oceanic-Oceanic
Continental-Continental
Converging-Oceanic
What do you call the broken segments that make up the lithosphere?
Crust
Mantle
Boundaries
Plates
Volcanoes form at hotspots that occur...
at convergent plate boundaries.
at divergent plate boundaries.
in the middle of a transform boundary.
in the middle of a tectonic plate.
This image shows the state of Hawaii. Why was an island chain created rather than one large island?
Hawaii sits on top of a hotspot; eight separate active volcanoes have formed as a result of the hotspot.
Hawaii sits on top of a hotspot; separate islands formed as the tectonic plate moved over time.
Hawaii sits on top of a hotspot; separate islands formed as a result of subduction of one oceanic plate under another.
Hawaii sits on top of a hotspot; eight separate active volcanoes formed due to the divergent plate boundary.
Oceanic-Oceanic convergence would most likely result in the formation of
ocean trenches and volcanic mountain ranges
volcanic islands and ocean trenches
mountain ranges without volcanic activity
valleys and volcanic arcs
