What is formed when one plate is forced under another?
mid ocean ridge
Explains locations of mountains, trenches, and volcanoes?
Mountains are formed by tectonic plate movements pushing crustal rocks together. Trenches are formed when one tectonic plate is forced beneath another, creating a deep depression in the ocean floor. Volcanoes are typically found at convergent plate boundaries or above hotspots in the Earth's mantle where magma rises to the surface.
What two crustal plates collide with one another?
Two types of crustal plates that can collide with one another are the continental plate and the oceanic plate, as seen in the convergence between the Pacific Plate and the North American Plate along the Cascadia subduction zone. Another example is the collision of two continental plates, such as the Indian Plate and the Eurasian Plate, which has formed the Himalayan mountain range. These collisions can lead to significant geological features and seismic activity.
What activity in the magma causes crustal plate movement?
The movement of magma beneath the Earth's crust can create convection currents, which push and pull on the crustal plates above. This movement can cause the plates to shift and collide, leading to processes such as subduction, where one plate is forced beneath another, or seafloor spreading, where new crust is formed along mid-ocean ridges.
What is the term for a piece of crust which has been in a collision along a convergent crustal boundary and become accreted to another crustal plate?
A terrane is the term used to describe a piece of crust that has been in a collision along a convergent crustal boundary and subsequently accreted to another crustal plate. Terranes are distinct geological units with their own history of formation.
Formed when one crustal plate is forced under another?
trenches
What is formed when one plate is forced under another?
mid ocean ridge
What are formed where an oceanic plate is forced underneath another plate?
Subduction zones are formed where an oceanic plate is forced beneath another plate, typically a continental plate. This process typically leads to the formation of deep oceanic trenches, volcanic arcs, and seismic activity due to the subduction of the oceanic plate into the mantle.

A trench forms when?
In geology a trench is formed where one tectonic plate is subducted or forced under another plate.

This movement can cause the plates to shift and collide, leading to processes such as subduction, where one plate is forced beneath another, or seafloor spreading, where new crust is formed along mid-ocean ridges.
What crustal features are formed by plate movement?
Crustal features formed by plate movements include mountain ranges (e.g. the Himalayas created by the collision of the Indian Plate with the Eurasian Plate), mid-ocean ridges (e.g. the Mid-Atlantic Ridge where new oceanic crust is formed), and deep ocean trenches (e.g. the Mariana Trench formed by subduction of the Pacific Plate beneath the Philippine Plate).
What is the term for a piece of crust which has been in a collision along a convergent crustal boundary and become accreted to another crustal plate?
A terrane is the term used to describe a piece of crust that has been in a collision along a convergent crustal boundary and subsequently accreted to another crustal plate. Terranes are distinct geological units with their own history of formation.
What forms when one plate is forced under another plate?
A subduction zone is formed when one tectonic plate is forced under another tectonic plate at a convergent boundary. This process can lead to the formation of oceanic trenches, volcanic arcs, and earthquakes. The subducted plate melts and contributes to the generation of magma that rises to the surface.
Which of these is a zone in which one plate is pushed down into the mantle underneath another plate?
This is known as a subduction zone. It is where one tectonic plate is forced beneath another due to tectonic forces, resulting in the recycling of crustal material back into the mantle. These zones are often associated with deep ocean trenches and volcanic arcs.
What are the crustal plate?
The seven crustal plates are African Plate, Antarctic Plate, Australian Plate, Eurasian Plate, North American Plate, South American Plate, and Pacific Plate.
What is irelands crustal plate?
the eurasian plate
