Select the two processes that occur at mid-ocean ridges.
A Material rises from the mantle to the crust.
B Sediments from the crust sink into the mantle.
C Crustal rock subducts into the mantle and melts.
D Thermal energy rises from the mantle to the crust.
E Tsunami waves transfer energy from the crust to the mantle.

Ridge push at slab pull. Ridge-push occurs when the weight of the ridge pushes the rest of the tectonic plate away from the ridge, often towards a subduction zone. Slab pull is when lithospheric plates move away from midocean ridges they cool and become denser. They eventually become more dense than the underlying hot mantle So i would say a and d are the closest to this but please try and double check and remeber ask teachers for help if you need it!

A mid-ocean ridge means a plate boundary that is least likely to be dangerous to humans. Material rises from the mantle to the crust and thermal energy rises from the mantle to the crust are the processes to occur at mid-ocean ridges.

What is the mantle?

A mantle refers to the layer above a crust. It constitutes the largest layer of the earth's interior.

The mid-ocean refers to the system made by plate tectonics. In this, two processes occur that are the material rise and thermal energy rise from the mantle to the crust.

Therefore, A and D are the correct option for this.
