honors objective: 1. for every boundary type covered in this unit, explain the types of rocks that are prevalent at each and why.

Answer

Brief Explanations:

There are three main rock - types: igneous, sedimentary, and metamorphic. At divergent boundaries, where tectonic plates move apart, magma rises to fill the gap, resulting in the formation of igneous rocks like basalt. At convergent boundaries, where plates collide, sedimentary rocks may be compressed and transformed into metamorphic rocks due to high pressure and temperature. Also, subduction of oceanic plates can lead to the melting of rocks and formation of igneous rocks through volcanic activity. At transform boundaries, where plates slide past each other, mechanical forces can cause rocks to break and deform, but rock - type formation is less directly associated compared to the other two boundary types.

Answer:

At divergent boundaries, igneous rocks (e.g., basalt) are prevalent because magma rises to fill the gap created by the separating plates. At convergent boundaries, metamorphic rocks can form from the compression and transformation of sedimentary rocks due to high pressure and temperature, and igneous rocks can form from subduction - related volcanic activity. At transform boundaries, while rock - type formation is less prominent, mechanical forces can cause rock deformation.
