Subduction results from convection in the asthenosphere. The heat from the core of the earth that is imparted to the mantle causes the mantle to convect much the way
boiling water convects in a pan on the stove. Hot mantle at the core-mantle boundary rises while cool mantle sinks, causing convection cells to form.

Which plate is subducting beneath South American plate?
Nazca
Does mars have a asthenosphere?
Mars does not have an asthenosphere like Earth. The asthenosphere is a layer in Earth's upper mantle that is semi-fluid and allows for plate tectonics to occur. Mars does not have active plate tectonics, so it does not have a comparable asthenosphere.
What kind of plate boundary has the most explosive volcanoes?
Convergent with the oceanic plate subducting under the continental plate.
Which plates is subducting beneath the South American plate?
The Nazca Plate is subducting beneath the South American Plate along the Peru-Chile Trench. This subduction zone is responsible for the formation of the Andes Mountains and the occurrence of frequent earthquakes in the region.
Which boundary destorys the crust?
Subduction boundaries, where one tectonic plate is forced below another, can destroy crust as the subducting plate melts and is absorbed into the mantle. This process can lead to the recycling of crustal material back into the Earth's interior.
When an oceanic plate digs into earth hot what occurs?
When an oceanic plate subducts below another continental or oceanic plate, the cold, wet, dense rock and sediments slowly dive into the asthenosphere, where, due to the volume of water contained in the subducting plate, the melting point of the subducting plate is lower than the surrounding rock. Volcanoes may result from the rising of molten material created by the subduction.
Are subducting plate and oceanic plate the same?
No, subducting plate and oceanic plate are not the same. An oceanic plate is a type of tectonic plate that lies beneath the ocean, while a subducting plate refers to an oceanic plate that is descending beneath another tectonic plate at a convergent boundary. Subducting plates are a specific category of oceanic plates.
When an oceanic plate digs into earths hot interior what occurs?
When an oceanic plate subducts below another continental or oceanic plate, the cold, wet, dense rock and sediments slowly dive into the asthenosphere, where, due to the volume of water contained in the subducting plate, the melting point of the subducting plate is lower than the surrounding rock. Volcanoes may result from the rising of molten material created by the subduction.
Which plate is subducting beneath South American plate?
Nazca
What is subducting ocean plate?
A subducting ocean plate is a tectonic plate that is moving beneath another plate at a convergent boundary. As it moves, the subducting plate is forced down into the Earth's mantle, creating a subduction zone. This process can lead to volcanic activity, earthquakes, and the formation of deep ocean trenches.
Do plate tectonics sit on the asthenosphere?
they sit on the asthenosphere
What is a subducting plates?
When one plate moves under the other plate
What type of plate boundary is asthenosphere?
The asthenosphere is not a plate boundary. It is the layer of Earth's mantle on which tectonic plates float.
Where is the asthenosphere and what does it do?
The asthenosphere is a section of the upper mantle that enables plate tectonics.
What is slabpull?
Slab Pull Force occurs when a denser oceanic plate is forced beneath a less dense continental plate or oceanic plate in a process called subduction. It's the force caused by suction of the cold dense lithosphere into the asthenosphere at destructive margins. Basically, because lithosphere is denser than asthenosphere, there is gravitational imbalance which is passed on to the crust. this causes the lithosphere to be sucked inwards at the oceanic trenches into deep asthenosphere.
Which plate is subducting beneath the south american plate to form the andes?
north american
Does mars have a asthenosphere?
Mars does not have an asthenosphere like Earth. The asthenosphere is a layer in Earth's upper mantle that is semi-fluid and allows for plate tectonics to occur. Mars does not have active plate tectonics, so it does not have a comparable asthenosphere.
