What do Earth's plates form when they move apart at some boundaries and that collide at others?

Mountains and volcanoes are formed when boundaries collide (a.k.a. convergent boundaries) volcanoes are formed at a subduction zone- mostly in the ocean. Mountains do NOT form at subduction zones.

First, you mean "when two tectonic plates", plates being the noun and tectonic an adjective. When they collide, we're talking over hundreds of thousands of years, ultimately one will go over the other, eventually sending the lower back to the Earths center. At some points, the plates will "get stuck" and when they "unstick", there will be sudden movement, i.e. an earthquake. It's also possible for both to go upwards and create a mountain range. Moving apart is different in that something must be pushing them apart. Currently, the only thing creating such a force is the chasm down the center of the Atlantic Ocean, from which matter is being pushed up and out from the Earth's core. This in turn is increasing the divide between Europe/Africa and North/South America.

Why are mountains constructive?
Mountains form at (convergent and divergent) plate boundaries. Two plates can crash together and bend upward, forming a mountain, or lava can harden into rack and build up volcanoes which are mountains.
Define Convergent Boundary?
In plate tectonics, a convergent boundary also known as a destructive plate boundary (because of subduction), is an actively deforming region where two (or more) tectonic plates or fragments of lithosphere move toward one another and collide. As a result of pressure, friction, and plate material melting in the mantle, earthquakes and volcanoes are common near convergent boundaries.
Divergent boundary tectonic plates?
In plate tectonics, a Divergent boundary or divergent plate boundary (also known as a constructive boundary or an extensional boundary) is a linear feature that exists between two tectonic plates that are moving away from each other. These areas can form on the end of continents but eventually form ocean basins. Divergent boundaries within continents initially produce rifts which produce rift valleys. Therefore, most active divergent plate boundaries are between oceanic platesand are often called mid-oceanic ridges. Divergent boundaries also form volcanic islands which occur when the plates move apart to produce gaps which molten lava rises to fill. Thus creating a shield volcano which would eventually build up to become a volcanic island.
What are the general ways that plates interact?
One of the way is they move towards each other and converge,or collide
Knowing the average speed of earths plates helps scientists?
it helps the scientists to predict future changes.
How does the surface of the earth change when two continental plates collide?
The Earths surface changes shape when plates collide when the earths surface overlaps or when there are Earthquakes.
Is convergent boundaries?
when two plates collide together
What type of boundaries formed when plates collide?
Convergent boundary
What is formed when the plates move apart at some boundaries and collide at others?
At collision, mountains, at separation, long deep holes into the earth.
What is when 2 plates boundaries bump together?
Two plates collide (bump together) at a convergent boundary.
How do foothills change over time?
When earths plates collide together
What are the types of boundaries found along the edges of earths plates?
convergent boundaries, divergent boundaries, transform boundaries and plate boundaries
What is the boundary between earths plates called?
Plate boundaries.
What happens at colliding boundaries?
these boundaries are formed when two plates collide. When the two plate bump one plate is absorbed in the mantle of the other. Heat and pressure when these plates collide causes volcanoes and earthquakes.
What is the relationship between plate boundaries and where earthquakes happen?
Plate boundaries are the absolute edges of the tectonic plates that make up our earth's crust. These plate boundaries clash with others making what are known as fault lines, which are the cause of earthquakes.
Where do earths plates meet?
at boundaries
Most earthquakes occur at the boundaries of these?
Most earthquakes occur at the boundaries of the tectonic plates. Tectonic plates are always in motion, and when two of them collide with one another it causes earthquakes.
