Why does oceanic lithosphere sink beneath convergent lithosphere at convergent boundaries?
As odd as it is to think of things this way, continental lithosphere is more buoyant than oceanic lithosphere. The oceanic lithosphere is more dense.
What happens to the density of new oceanic lithosphere when it cools?
As the lithosphere cools, asthenosphere's hot rocks freeze onto their undersides. So lithosphere becomes thicker. As time goes on or within the time period of 10 million years, it even becomes thicker than asthenosphere.
Why does oceanic lithosphere sink at subduction zones but not at mid ocean ridges?
oceanic lithosphere sinks at subduction zones but not at mid ocean ridges because at subduction zones the oceanic lithosphere is subducted, or sinks, under another plate. Oceanic Lithosphere sinks at subduction zones which are usually at convergent boundaries, but at mid-ocean ridges the plates are actually separating not coming together
Where is the oceanic lithosphere subducted?
The oceanic lithosphere is subducted at convergent plate boundaries, where an oceanic plate meets a continental plate or another oceanic plate. This process typically occurs in areas known as subduction zones, characterized by deep ocean trenches. As the denser oceanic lithosphere sinks into the mantle, it leads to geological phenomena such as volcanic activity and the formation of mountain ranges.
Does cooler material in the asthenosphere rises towards the lithosphere?
Yes, cooler material in the asthenosphere can rise towards the lithosphere due to convection currents. As the cooler material sinks, it displaces warmer material, creating a cycle of movement within the asthenosphere. This movement can contribute to the tectonic plate motion on the Earth's surface.
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.

How are ridge and slab pull related to convection in Earths mantle?
they are related because they all have to do with the oceanic lithosphere.The convection causes the lithosphere to move sideways and away from the midocean ridges.The ridge push makes the oceanic lithosphere slide downhill under the force of gravity. The slab pull:the old lithosphere is denser than asthenosphere so, the edge of the tectonic plates that contains oceanic lithosphere sinks and plls the rest of the tectonic plate.

The force on the the rest to the plate from the asthenosphere below cooling sinking rock is called?
The force on the lithosphere from the asthenosphere below due to cooling and sinking rock is called slab pull. This force is one of the driving mechanisms behind plate tectonics, where the denser oceanic lithosphere sinks into the mantle, pulling the rest of the plate along with it.

Where slab of oceanic lithosphere are subducted under continental lithosphere?
Oceanic lithosphere is subducted under continental lithosphere at convergent plate boundaries. This process occurs when the denser oceanic plate sinks beneath the less dense continental plate, creating deep ocean trenches and volcanic arcs. The subducted oceanic plate eventually melts and contributes to the formation of magma that leads to volcanic activity.
