4.3 Where do igneous rocks appear in a landscape?

Exposure of plutonic rocks requires erosion.
Once exposed, plutonic rocks exhibit characteristics related to intrusive processes, as well as the erosion.
Volcanic rocks includes lava flows and pyroclastic deposits and flows.
Magma compositions, conduit shapes, and volumes and ratios of eruptive materials determine volcano size and shape.
Calderas form when drained magma chambers collapse from the overlying weight.
