Why do oceanic plates move under continental plates when the two collide?
Oceanic plates are denser than continental plates, so when they collide at a convergent boundary, the denser oceanic plate is forced to subduct beneath the less dense continental plate. This subduction is driven by the force of gravity pulling the denser plate downward. This process can lead to the formation of volcanic arcs and deep ocean trenches.
What are three types of convergent boundaries?
Oceanic-continental convergence: Oceanic plates sink beneath continental plates, creating subduction zones and mountain ranges. Oceanic-oceanic convergence: When two oceanic plates collide, one plate is subducted beneath the other, leading to trench formation and volcanic island arcs. Continental-continental convergence: Two continental plates collide, resulting in the uplift of crust and the formation of mountain ranges.
What is the difference between Continental plates and Tectonic plates?
Continental plates are tectonic plates. They are tectonic plates upon which continents rest, and they move as do all tectonic plates. Basically, there is no difference, other than the fact that oceanic plates are another type of tectonic plate.
Compare and contrast the three plate boundaries?
Oceanic-continental convergence (when an oceanic plate meets a continental plate) & oceanic-oceanic convergence (2 oceanic plates) both involve oceanic plates & subduction. Continental-continental convergence (2 continental plates) involves neither.
What happens when 2 oceanic plates and 2 continental plates move towards each other?
When 2 oceanic plates and 2 continental plates move towards each other, subduction occurs. The denser oceanic plate sinks beneath the less dense continental plate, creating deep ocean trenches and volcanic arcs. This process can lead to the formation of mountain ranges and earthquakes.

Do tectonic plates consist of continental or oceanic crust?
Tectonic plates consist of both continental and oceanic crust. The Earth's lithosphere is divided into several large and small plates that constantly move and interact with each other. Some plates are predominantly made up of continental crust, while others are mostly composed of oceanic crust.

What are tectonicsplates?
Tectonic plates.Tectonic plates are plates underneath Earth's surface that move very slowly. There are oceanic and continental plates. Of course, oceanic plates are plates under the ocean, and continental plates are plates underneath ground, or continents. Each of the plates carry the things above them, land or ocean. When two continental or oceanic plates collide, it causes a fold in Earth's surface, and an earthquake. Now, when a continental plate draws near and nearly collides with an oceanic plate, something called subduction occurs. Subduction is basically when the oceanic plate dips down below the continental plate, causing a trench.

What are types of convergents boundaries?
Converging (destructive) plate boundary: where two plates collide. Diverging (constructive) plate boundary: where two plates move away from each other. Transform plate boundary: where two plates move, or grind, past each other. Like the boundary in California.
What happens when 2 oceanic plates and 2 continental plates move towards each other?
When 2 oceanic plates and 2 continental plates move towards each other, subduction occurs. The denser oceanic plate sinks beneath the less dense continental plate, creating deep ocean trenches and volcanic arcs. This process can lead to the formation of mountain ranges and earthquakes.
What are the types of divergent boundaries?
The 3 general types are constructive, destructive, and conservative boundaries. Constructive (divergent) - plates move away from each other, typically creating a rift Destructive (convergent) - one plate will be subducted, or continental plates collide Conservative (transform) - plates grind past each other, stalling and slipping
Do continental plates move constantly?
Yes, they move slowly but constantly. Faster during earthquakes.
Tectonic plates can include?
Oceanic plates, continental plates, and microplates are all examples of tectonic plates that make up the Earth's lithosphere. These plates move around due to the heat-driven convection currents in the Earth's mantle, causing phenomena like earthquakes, volcanoes, and mountain-building.
What are plates moving away from one Another?
When plates move towards each other it is called a convergent boundary. The two types of plates converging depends on what happens. When it is oceanic/oceanic, both plates subduct (go downward), leading to the creating of trenches found at the depths of the ocean. When an oceanic plate converges with a continental plate, the more dense oceanic plate subducts under the continental plate, again creating trenches, and also leading to the destruction of the ocean floor. When continental plates converge, they tend to smash up and rise, creating mountains. When plates move apart, it is called a divergent boundary. When oceanic plates move apart, magma rises, cools, and solidifies to create new ocean floor. This, along with continental/oceanic convergence, accounts for seafloor spreading. When two continental plates diverge, the area left between them slowly turns into an ocean. For an example of this type of ocean, look at the Red Sea.
