What type of friction do the Nazca and South American plates have?

Explanation:

The tectonic plates move among themselves as solid and rigid blocks, moving over the upper level of the mantle (asthenosphere).

When the plates get closer to each other, we say that they converge → ←, when they separate they diverge ← → and if what they do is move laterally next to each other they pass ⇅

In the case at hand, the Nazca oceanic plate converges with the South American continental plate, approaching each other at a rate of about 6 or 8 cm per year. And they have been doing so for at least the last 25 million years.

Since the Nazca plate, due to its composition, is denser than the South American plate, it has less buoyancy and when pushed against it, it folds and sinks towards the mantle where it melts. This process, called subduction, is responsible for the rising of the Andes, as well as the high seismicity and volcanism present along the South American west coast.

since there isn't any suggested answers i will give you the reason and hopefully you can figure it

south africa, or rather all of africa, has not been in the location in which it is nowadays throughout the geological past. after the super-continent pangaea started to break apart, gondwanaland, in which was africa, moved further south, and parts of it came to be very close to the south pole. because the climate in this part of the world is very cold due to the very dispersed sun rays in there, what is now south africa, started to freeze, and the conditions were right for the formation of glaciers. the glaciers existed up until the period when gondwanaland started to break apart and what is now africa started to move towards north, sp it warmed up and the glaciers melted.

a mid-ocean ridge or mid-oceanic ridge is an underwater mountain range, formed by plate tectonics. this uplifting of the ocean floor occurs when convection currents rise in the mantle beneath the oceanic crust and create magma where two tectonic plates meet at a divergent boundary.a geomagnetic reversal is a change in a planet's magnetic field such that the positions of magnetic north and magnetic south are interchanged.
