What else can I help you with?
What happens to the old ocean floor as the sea floor spreads?
As the sea floor spreads, the old ocean floor gets pushed out, which makes the plates move.
What is the largest landforms caused by plates?
5 landforms caused by plate movements are (sorry if this is wrong!): mountains, volcanoes, deep-ocean trenches, plateaus, and mid- ocean ridges.HOPE THIS HELPED YOU!!!!!!!!!!!!!!!!!!!!!!!!!!! =D =)
What causes tsunami and earthquakes in Japan?
Earthquakes in Japan are caused by the movement of tectonic plates. A tsunami is a large ocean wave that is caused by sudden motion on the ocean floor which can be triggered by earthquakes.
What force makes cold water sink toward the ocean floor?
gravity
A long narrow and very deep canyon where the ocean floor bends down toward the mantle is called what?
A long narrow and very deep canyon where the ocean floor bends down toward the mantle is called an ocean trench. This is caused by two plates pulling apart.
When two of earths ocean plates collide they can form a deep valley called?
When two of Earth's oceanic plates collide, they can form a deep valley called a trench. Trenches are often found in subduction zones where one plate is forced beneath the other, creating a deep depression in the ocean floor.
When ocean plates collide with continental plates what does the denser plate do?
sinks
When two oceanic plates collide it creates?
when two oceanic plates collide they create a deep-ocean trench, at deep-ocean trenches subduction occurs.
What occurs on the ocean floor when plates collide?
the contintinental plate goes below the other and lava floating from the center of the earth creates a ridge
When ocean plates collide with continental plates the denser oceanic plate?
sinks
When oceans plates collide with continental plates the denser ocean plate does what?
sinks
What is ocean's trench?
Ocean trench is a long, narrow and deep depression in the ocean floor.
What land form is created by tectonic plates crashing together?
this depends on the two plates that collide. Ocean plates are much heavier than continental plates. If an ocean and continental plate collide, the ocean plate sinks underneath and creates a trench. If two ocean plates or two continental plate collide, it creates a mountain range/ oceanic ridge depending on the type.
What is things rest upon crustal plates?
The continents and the ocean floor rest upon the plates.
Are formed when two ocean plates collide?
volcanoes in an island arc
What are the differences between oceanic crust and continental crust in age terms?
Overall their materials are of the same age, but the continental plates simply break or collide whereas the ocean-floor plates are in constant cycles of construction and destruction.
What type of boundary is formed when plates collide?
When plates collide it is called a convergent boundary.newtest3
