The underside surface of a tectonic plate can form various geological features depending on the interactions occurring there. For example, at divergent boundaries, new oceanic crust is created as magma rises and solidifies. At convergent boundaries, subduction can lead to the formation of deep ocean trenches and volcanic arcs. Additionally, sedimentary deposits may accumulate on the underside if the plate is part of a larger geological process.

What happens when an oceanic plate moves under a continental plate?
When an oceanic plate moves under a continental plate, a subduction zone is formed. The oceanic plate is forced down into the mantle, where it melts and creates magma. This magma can then rise to the surface, causing volcanic activity on the continental plate.
How was the volcano in Montserrat was formed?
by an undersea volcano that erupted from the ocean's floor. Spewing its lava (molten rock), the volcano built an undersea mountain that grew higher and higher, eventually growing above the surface of the sea.
Was Japan formed by the Pacific plate moving over the Eurasian plate?
Japan is a string of volcanic islands which are formed at a convergent-subduction boundary. In this case, the subducted island was the Pacific Plate. When the pacific plate was subducted, the crust heated to form magma and expanded, pushing the Eurasian Plate upwards. This new magma close to the surface began breaking through the surface and forming volcanoes which eventually became islands.
What geologic feature is formed of the surface of an oceanic plate when it collides with a continental plate?
When an oceanic plate collides with a continental plate, a subduction zone is formed, leading to the creation of a trench at the oceanic plate's edge. The denser oceanic plate is forced beneath the lighter continental plate, resulting in volcanic activity and the formation of mountain ranges on the continent. This interaction can also lead to significant geological events such as earthquakes. Overall, these features reflect the dynamic processes of plate tectonics.
How are volcano island formed?
It is formed by a convergent boundary of an oceanic plate and continental plate when they hit each other and goes down into the asthenosphere thus making the magma to rise above the earth's surface making a volcano.Then it solidifies and therefore it makes a volcano island.
What is formed on the underside of the plate?
water bells
Which type of mountain is not formed to plate collision?
Volcanic mountains are not formed by plate collision. These mountains are created when magma from within the Earth's mantle rises to the surface and solidifies.
What type of plate boundaries formed the laki system located in Southern Iceland?
surface
How was Mount Taranaki formed?
It was formed by the pacific plate sub ducting beneath the Australian plate. The pacific plate slides into the earths mantle, where it melts. the molten rock then rises to the surface because it is less dense and forms a volcano
What is skid plate?
The plate on the underside of the vehicle that protects the vital areas of an engine or transmission.
What type of mountain in not formed due to plate collision?
Volcanic mountains are not formed due to plate collision. Instead, they are formed when magma from within the Earth erupts onto the surface and builds up layers of volcanic rock over time.
What happens when an oceanic plate moves under a continental plate?
When an oceanic plate moves under a continental plate, a subduction zone is formed. The oceanic plate is forced down into the mantle, where it melts and creates magma. This magma can then rise to the surface, causing volcanic activity on the continental plate.
When earth was formed its whole surface was comprised of which rock?
The Earth's original surface was likely made of basaltic rock, which is formed from solidified lava. Over time, geological processes such as weathering and plate tectonics have altered the surface composition of the Earth.
How was the volcano in Montserrat was formed?
by an undersea volcano that erupted from the ocean's floor. Spewing its lava (molten rock), the volcano built an undersea mountain that grew higher and higher, eventually growing above the surface of the sea.
Is the mouth of a starfish on the upper surface?
no it is in the middle of the underside

This new magma close to the surface began breaking through the surface and forming volcanoes which eventually became islands.
How do the plates make mountains?
When one tectonic plate presses into another it can either force it upwards or downwards. If it is upwards, then mountains are formed as the plate pushes up the surface of the earth above it.
