What are seismic plates?
seismic plates, or tectonic plates, are huge 'plates' of rocks that exist beneath the earth's surface that rest upon molten rock. It is on the borders of these plates that 'fault lines' occur and these are hotspots of volcanic and seismic activity such as earthquakes.
What happens during sudbuction?
During subduction, one tectonic plate is forced beneath another plate into the Earth's mantle. This typically occurs at convergent plate boundaries where two plates collide. As the subducting plate sinks into the mantle, it can cause various geological phenomena such as earthquakes, volcanic activity, and the formation of mountain ranges.
What happens when plate tectonics move up or down?
When plate tectonics move up or down, it is referred to as vertical movement or vertical displacement. Upward movement can occur due to processes like uplift and volcanic activity, leading to the formation of mountains and volcanic landforms. Downward movement, on the other hand, can result in subduction zones where one tectonic plate is forced beneath another, causing the formation of trenches and sometimes leading to earthquakes and volcanic activity.
Where does the volcanic activity in the earth occur?
The most volcanic activity is in the Bermuda triangle or "the Devils triangle". It is located in an area located off the southerneastern Atlantic coast of the united states. It is also known for the unexplainable disappearence of ships and aircrafts.
What hazards do divergent boundaries cause?
Convergent boundaries, the junction where two or more plates meet causes a number of things to occur. 1) The denser oceanic plate subducts (to sink beneath) the lighter continental crust at this point the rock of the oceanic crust starts to melt (assimilation) and is referred to the "B subduction" zone or Wadati-Benioff Zone or boundary. Here volcanoes are formed by the heat released from the melting rock and trenches form where the oceanic subducts the continental 2) In a scenario where two continental plates meet fold mountains are formed but a process called "A" subduction as neither plate will want to subduct causing them to fold and buckle like a carpet forced onto a wall.
What is the difference between a passive continental margin an an active continental margin?
Passive continental margins are not areas of convergence. There is little volcanic and earthquake activity on passive margins. Active margins are areas of convergence where one plate is descending beneath another. They are associated with volcanic and earthquake activity.
Can earthquakes occur when a volcano erupts?
Yes. In fact, earthquakes and tremors usually precede the eruption of a volcano and are caused by the volcanic activity and pressure building up beneath the ground.
How do active margins differ from passive margins?
Passive continental margins are not areas of convergence. There is little volcanic and earthquake activity on passive margins. Active margins are areas of convergence where one plate is descending beneath another. They are associated with volcanic and earthquake activity.

What is continental volcanic arc?
I think its a chain of volcanoes form when oceanic crustsubducts beneath other oceanic crust on an adjacent plate. . (:
Explain the abundance of andesite of leyte?
Andesite is abundant in Leyte due to the volcanic activity in the region. Leyte is part of the Pacific Ring of Fire, a region known for its high volcanic activity, which has resulted in the widespread presence of andesite. This volcanic rock is formed from the solidification of magma beneath the Earth's surface and is commonly found in areas with past or present volcanic activity.

As the subducting plate sinks into the mantle, it can cause various geological phenomena such as earthquakes, volcanic activity, and the formation of mountain ranges.

Do earthquakes cause volcanoes to explode?
In most cases, no. However, there is evidence that, on a few occasions, earthquakes appear to have triggered eruptions, most likely by disturbing the magma chamber beneath the volcano. Earthquakes often precede a volcanic eruption, be these are not the cause of the eruption, but are rather a result of the movement of magma that leads to an eruption.

What happens when an oceanic plate collides with a continental plate?
when oceanic crust and continental crust collide, the oceanic crust sinks down beneath the continental crust. this is called subduction.
