Describe the type of plate boundary which you think is present along the west coast of South America

The South American Plate is the smallest major plate

At the west side of South America, it experiences devastating earthquakes due to the convergent plate tectonic boundaries. But the eastern edge lies in the Atlantic Ocean at a divergent plate boundary.

Explanation:

heat released by collision processes during accretion, and heat from decay of radioactive elements

explanation:

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.
