Document Summary

Directly produced by volcanic and tectonic activity. Shaped by processes of and agents of denudation. Ring of fire: is associated with tectonic processes. Oceanic crust: mafic rocks (rich in magnesium and iron; denser) Continental crust: upper portion is primarily felsic rocks (rich in silicate minerals; less dense) Mafic: dark rocks less rich in silicate. Felsic: lighter, less dense: explains why subduction happens. Oceanic crust is denser and is able to be pulled under the continental crust. Calderas: large steep sided circular depression resulting from. Collapse of a volcano after emptying of magma chamber. Thermal features: groundwater can be heated when hot rock and molten material is near the surface, this results in hot springs and geysers, often found near active or recently dormant volcanoes, e. g. Tectonic processes: recall compression and extension, usually associated with converging and separating plate boundaries(respectively) Tectonic landforms: fold belts, faults and fault landforms. Over thrust: recall that compression and extension are associated with movement of plates.
