Plate boundaries behave in different ways, depending on the location and their motion. Identify the possible outcomes for a divergent boundary.
rift valley and mid-ocean ridge
deep ocean trenches and earthquakes
mountain building and subduction
volcanoes and seamounts
The interactions at plate boundaries cause huge changes on both the land and the ocean floor. What are the mountains results from the type of plate boundary?
divergent
convergent
transform
strike-slip fault
What events can produce an earthquake?
the force of tsunamis in the oceans
a sudden release of energy from the mantle
movement of tectonic plates along a fault
the violent shaking of sections of the lithosphere
The movement of Earth’s plates causes changes in the Earth’s crust.The form of the mountain range, what type of plate boundary would most likely occur?
convergent boundary with subduction
convergent boundary without subduction
divergent boundary
transform boundary
What is the most responsible for the recycling of crust when two plates meet?
magma rising up from the mantle at a divergent boundary
two tectonic plates sliding past one another at a transform boundary
subduction of one oceanic plate under another at a convergent boundary
formation of new crust when two continental plates at a convergent boundary
What is the correct definition of a tectonic plate boundary?
At a divergent boundary, plates separate.
At a transform boundary, plates move apart.
At a convergent boundary, plates slide past each other.
At a divergent boundary, one plate sinks under another plate.
The Himalaya Mountains formed when the Indian tectonic plate collided with the Eurasian plate. Describes this process?
ridge push
divergent boundary
transform boundary
convergent boundary
The Atlantic Ocean formed as the South American Plate moved apart from the African Plate. Which type of boundary was involved in the formation of the Atlantic ocean?
transform boundary
divergent boundary
stationary boundary
convergent boundary
What happens at a transform tectonic plate boundary?
Two tectonic plates move horizontally past one another along Earth’s surface, forming long fault lines.
Two tectonic plates pull away from one another, forming a rift or ridge.
Two tectonic plates pull away from one another, decreasing rock deformation.
Two tectonic plates collide with one another, causing subduction and/or mountain building.
Identify the process that causes tectonic plates to move?
Conduction in the inner core
Convection in the inner core
Convection in the mantle
Conduction in the mantle
Why the magma inside the Earth may start to rise?
because the surrounding rock is cooler
because the surrounding rock is less dense
because the surrounding rock is more dense
because the surrounding rock is more viscous
What describes the pot of water on a hot stove of the convection cycles that heat up the water?
warmer, more dense fluid rises and cooler, less dense fluid sinks
warmer, more dense fluid sinks and cooler, less dense fluid rises
warmer, less dense fluid rises and cooler, more dense fluid sinks
warmer, less dense fluid sinks and cooler, more dense fluid rises
What is the cause of sea-floor spreading?
the development of deep water ocean trenches with magma that comes from Earth’s crust due to convection currents
ocean floor sedimentation that develops over millions of years that adds sedimentary rock layers
the flow of magma from the mantle through cracks in Earth’s crust that makes strips of new rock on both sides due to convection currents
a plate of dense oceanic crust sinks below a less dense plate of continental crust to form an undersea valley
Between mountain building, volcanoes, and earthquakes. What's there relationship?
They mostly occur in the oceans and in the center of plates at land boundaries because of convection currents.
They mostly occur at plate boundaries and are generated from eruptions that occur on land due to convection currents.
They mostly occur in the oceans and change the sea floor by spreading apart to make new rock.
They mostly occur at plate boundaries and are generated by plate motions from convection currents.
What are the result of high temperatures in Earth’s mantle?
earthquakes and volcanoes
radioactive atoms in minerals
ocean tides
erosion and deposition
What is a convection current?
the transfer of energy by direct contact
the transfer of energy by the movement of matter
the transfer of energy through a solid, such as the Earth’s crust
the transfer of energy from a region of lower temperature to a region of higher temperature
