Record my thinking rock cycle
Processes that take place at the surface of the Earth include weathering, transportation and deposition, as well as biological processes such as the growth of some of the animals and their shells or skeletons, which form parts of sedimentary rocks. The rock cycle not only sets the three main groups of rocks into a spatial context, it also links them through processes of formation and transformation. The second branch is labelled ‘crystallisation and intrusion’ and leads to intrusive igneous rock. At this point ‘magma erupts’ and leads to extrusive igneous rock. The first branch continues with ‘magma rises’ as it leads to a volcano.

A red arrow in the magma, also marked ‘melting’ leads back up, where it's then labelled ‘magma rises’, and here the magma branches off. Along the bottom are ‘magma from depth’ and ‘heat from depth’, with short red arrows that point upwards. This is the deepest section displayed on this diagram. From metamorphic rock, the green arrow ‘melting’ leads to underground magma. And from here, the green arrow ‘subsidence and burial’ leads back down to metamorphic rock. Both sedimentary and metamorphic rock also follow orange arrows that lead back up to the surface, labelled ‘uplift’. Beneath this are green arrows labelled ‘subsidence’ and ‘metamorphism’, ‘heating and compression’, leading to metamorphic rock. This leads to a sea bed where the deposition of sediments causes ‘burial and compaction’ (green arrow). At the top there are mountains with rainclouds above them, and a blue arrow indicating ‘weathering and erosion’, leading downhill to ‘transportation’, ‘deposition’. The typical sorts of terrain involved in these processes are seen in a cross-section diagram of earth. This diagram shows the various processes that form the rock cycle. A good way of viewing how different types of rock may be connected by processes that form and re-form them is through a conceptual system known as the rock cycle.

This can be a single crystal grain decomposing during weathering, to the ocean being formed as a result of the long strings of volcanoes that exist along the ocean floors (more on that later). These two topics are what you’ll be studying for the rest of this week.Īll three sorts of rocks are continually being created, modified and destroyed by many different geological processes, operating at all scales of both length and time. It is described by a conceptual system called the ‘rock cycle’ and one of the main processes involved is plate tectonics. What parts of the rock cycle happen underground and out of our sight? What parts can we see happening? Look at the rock cycle diagram.You have already tried to identify rocks that are used in your local area as either igneous, sedimentary or metamorphic, but have you ever thought about how rocks end up in these categories? Or, if rocks are broken down into clasts, will we ever run out of rock to form sedimentary rocks with? Luckily, the answer to the last question is no – this section will investigate how rocks change between these three categories.
