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?
trench- valleys that form on the ocean floor where two plates come together, the deepest place in the ocean
When ocean plates collide with continental plates the denser ocean plate?
sinks
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 oceans plates collide with continental plates the denser ocean plate does what?
sinks
When ocean plates collide with continental plates the denser oceanic plate?
sinks
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 leads to the creation of island arcs?
When two ocean plates collide.
What is ocean's trench?
Ocean trench is a long, narrow and deep depression in the ocean floor.
Are formed when two ocean plates collide?
volcanoes in an island arc
What is formed on the bottom of the ocean where two plates collide?
continental slope
