Question: Describe the types of crust that the south american plate is made up of.

The South American Plate has two main types of crust:

Continental Crust: This type forms the landmass of South America. It's thicker but less dense than oceanic crust, composed mainly of granite and other light silicate minerals.

Oceanic Crust: Found beneath the Atlantic Ocean, this is thinner and denser, composed mostly of basalt and gabbro. It's constantly being renewed at mid-ocean ridges where tectonic plates diverge.

These two types interact at the plate's boundaries, contributing to geological activity like earthquakes and volcanic eruptions.
