At convergent boundaries, plates move toward each other. They can push together and cause mountain ranges to form. At other times, one plate gets pushed down beneath the other plate. This can cause volcanoes.
Q. Why do the plates move geography?
Why do plates move? One explanation for plate movements is slab pull. Plates are extremely heavy so gravity acts upon them, pulling them apart. Alternatively, as shown in the diagram, convection currents under the Earth’s crust transfer heat, which rises through the surface and cools back down in a circular motion.

Q. What happens when the plate move?
When the plates move they collide or spread apart allowing the very hot molten material called lava to escape from the mantle. When collisions occur they produce mountains, deep underwater valleys called trenches, and volcanoes. The Earth is producing “new” crust where two plates are diverging or spreading apart.
Q. Do plates move constantly?
Earth’s tectonic plates are in constant motion. Their movement is driven by heat within the Earth. This causes hot material within the Earth to rise, until it reaches the surface where it moves sideways, cools, then sinks. This circular motion is called convection.
Q. What geologic features form when two plates move?
Deep ocean trenches, volcanoes, island arcs, submarine mountain ranges, and fault lines are examples of features that can form along plate tectonic boundaries. Volcanoes are one kind of feature that forms along convergent plate boundaries, where two tectonic plates collide and one moves beneath the other.
Q. What happens to the material of a plate that goes under nearby plates?
Subduction is a geological process that takes place at convergent boundaries of tectonic plates where one plate moves under another and is forced to sink due to high gravitational potential energy into the mantle. Plates include both oceanic crust and continental crust.
Q. What happens to the plate that gets subducted?
When a tectonic plate gets subducted, it sinks underneath another tectonic plate. The crust is heated and melts as it enters the mantle and the rock…
Q. What happens when two plates of the same density collide?
When two plates (either oceanic or terrestrial) converge and they are of similar density then they will crash into each other and form mountains. A great example of this is when India crashed into the Asian continent and the Himalayas were formed.
Q. When two plates slide past each other what is the boundary called?
