According to the theory of plate tectonics, earth’s surface is composed of many sections of crust and solid upper mantle. forces within the earth cause the sections, or plates, to move. some of the plates converge while others diverge. name two geological events that are associated with this type of activity.

The West Coast of South America is a convergent boundary between the Nazca Plate and the South American Plate.

The Arabian plate is running up on the Eurasian plate.

metamorphism is the change of minerals or geologic texture (distinct arrangement of minerals) in pre-existing rocks (protoliths), without the protolith melting into liquid magma (a solid-state change). the change occurs primarily due to heat, pressure, and the introduction of chemically active fluids. i hoped i !
