How does the movement of tectonic plates form ocean trenches?
The tectonic plates, oceanic-to-oceanic convergent boundaries or oceanic-continental convergent boundaries create the ocean trenches. One of the plates that is denser than the other is pushed downwards into the mantle of the Earth by the lighter, and less dense plate. This creates the trench due to the downward motion of the plate. The denser plate's gravity will pull the rest of the plate down with it with time. Divergent Boundaries underwater is only present at oceanic ridges. This creates the seafloor spreading. The hot magma that may be in an area pushes the older rocks (part of the plate) away from each other, causing a spreading motion.
What are the Two ways that mountains are created?
Fold moutains are actually formed by crust which have been uplifted and folded by compressional forces. This occurs along convergent plate boundaries where 2 plates move towards each other, between continental plates or between an oceanic and a continental plate. The crust and the rocks get bent and crumpled, and massive layers of Earth's crust gets uplifted as a result, forming spectacular fold mountains. More well-know examples of fold mountains are the Himalayas in Asia and the Andes in South America.
What are divergent boundaries?
Divergent boundaries are areas where continental or oceanic plates are moving away from each other and creating new crust. Examples would be the Mid-Oceanic Ridge and the East African Rift Zone.
When one tectonic plate pushes underneath another what boundary is formed?
well, there's two things. one, it's a convergent plate boundary, and two, it's called subduction when one plate goes under.
What plate causes volcanoes?
What type of boundaries cause volcanoes? Divergent and transform fault boundaries cause volcanoes because they separate. Convergent boundaries cause earthquakes because they collide with other plates.
What is it called when two tectonic plates pushes into each other?
Convergent Boundary
What happens when a plate gets subducted?
The colder, more dense plate is the one that subducts in a collision between two plates. In an oceanic to oceanic plate collision it is the older of the two plates that will subduct due to its higher density. In an oceanic to continental plate collision, it's the oceanic plate that will subduct because of its higher density.

What type of plate boundary is the Andes mountains?
The type of boundary that the Andes mountains are, in South America, is a convergent plate boundary. This was formed from the collision of the South American plate boundary and the Nazca plate.
What is the spatial association and spatial interaction between tectonic plates and volcano locations?
Many volcanos occur along tectonic boundaries, whether they are convergent (pushing together) or divergent (pulling apart). These boundaries typically occur between continental and oceanic plates or between two oceanic plates. Some volcanos however are created by hot spots where molten magma from the mantle of the Earth pushes through the crust, these hot spots can form islands such as the Hawaiian Islands.
What are divergent boundaries?
Divergent boundaries are areas where continental or oceanic plates are moving away from each other and creating new crust. Examples would be the Mid-Oceanic Ridge and the East African Rift Zone.
How do volcanos form at a plate boundary?
When tectonic plates converge together at the bottom of the ocean the oceanic plate goes under the continental plate because the oceanic plate weighs more and then the oceanic plate pushes up the continental plate which forms mountains and sometimes the tectonic plates let magma through which goes up through the continental plate and then opens a hole at the top of the mountains called a vent which is where the steam, volcanic ash, debris and lava come out of.
How does the Earth's crust can move to make fold mountains?
because there is something called convergent boundary and that's when the crust pushes against the crust forming a mountain.
How do you explain the process of the seafloor spreading?
The seafloor spreading definition is the geologic process that occurs at the boundary between 2 plates where molten material within the earth pushes its way up, causing the plates to move away from each other. At these divergent boundaries molten material cools and hardens, creating new oceanic crust or seafloor

What plate causes volcanoes?
What type of boundaries cause volcanoes? Divergent and transform fault boundaries cause volcanoes because they separate. Convergent boundaries cause earthquakes because they collide with other plates.
