At point 4

Explanation:

Subduction is a geologic process which occurs at convergent plate margins.

Subduction occurs when a denser lithospheric plate goes beneath the lighter one. Generally, the lithosphere is made up of the crust and part of the mantle. The two moves slowly on the weak and plastic asthenosphere.

In a convergent plate margin, two plates comes together. When two plates comes together, it is either we have collision or subduction. When subduction occurs, denser plates goes beneath the less dense ones.

The average density of the continental crust is 2.9g/cm³ while that of the oceanic crust is 3.3g/cm³. The oceanic crust geos beneath the continental crust because it is denser. This is subduction.

increasing transnational kinetic energy. because the transnational kinetic energy formula consists of only two variables, mass and velocity, increasing one of those properties is the only way to increase an object's transnational kinetic energy. increases to mass and velocity, however, do not have the same impact.
