boxwork weathering
Internal processes which have been involved in the formation of boxwork weathered rocks.
The major internal processes for my surface feature are:
1. The rock cycle and the formation of greywacke.
2. The uplift that brought the rocks from under the ocean up to the shore level.
The rock cycle
The rock cycle refers to the diverse set of natural processes that lead to the formation and transformation of igneous, sedimentary, and metamorphic rocks. The rock cycle shows that each type of rock can change in a certain way to form another. The driving force of the rock cycle is plate tectonics.
The transition to igneous is when rocks are pushed deep under the earth’s surface and may melt into magma, if there is no condition for the magma to stay in a liquid state, it will cool and solidify into an igneous rock. The three main types of rocks can melt into magma and cool to form igneous rocks. The start of the cycle can be placed at the mid-ocean divergent boundaries where new magma is produced by mantle upwelling and a shallow melting zone. This new magma is the first phase of the igneous part of the cycle. The types of igneous rocks are Granite, Pumice, Obsidian, Andesite, Rhyolite and Basalt. There are large amounts of Rhyolite found in Taupo and Rangitoto Island is made of Basalt.
The transition to metamorphic is when sedimentary or igneous rocks change in structure and appearance by the exposure of high temperatures and pressure over time. As the oceanic crust is pulled back into the mantle, the increasing pressure and temperature conditions cause a reform of the mineralogy of the rock, this metamorphism. My surface feature is a greywacke rock and greywacke is semi-metamorphosed. The types of metamorphic rocks are Greywacke, Slate, Schist, Marble and Sandstone.
The transition to sedimentary the earth’s surface is always eroding this means rocks are being broken into smaller pieces by weathering of wind, water and ice. By erosion and weathering sediments are
