THE ROCK CYCLE
BY EDWARD SALMON - SMITH

Types of rock.
There are three types of rocks. Sedimentary, for example chalk, limestone, sandstone and shale. Igneous, for example basalt and granite. Finally, Metamorphic, for example slate and marble.

What is the rock cycle?
The Earth's rocks do not stay the same forever. They are continually changing because of processes such as weathering and large earth movements. The rocks are gradually recycled over millions of years. This is called the rock cycle.
For example sedimentary rocks can be changed into metamorphic rocks, and these can be weathered and the pieces transported away. These pieces could be deposited in lakes or seas and eventually form new sedimentary rock. Many routes through the rock cycle are possible.

Diagram

Key words from the diagram.
Sedimentation creates layers or rock particles.
Compaction and cementation presses the layers and sticks the particles together. This creates sedimentary rock.
Rocks underground that get heated and put under pressure are changed into metamorphic rock.
Rocks underground that get heated so much they melt turn into magma. Magma is liquid rock. Magma also comes from deeper inside the Earth, from an region called the mantle.
Pressure can force magma out of the ground. This creates a volcano. When the magma cools it turns into solid rock, called extrusive igneous rock.
Magma that cools underground forms solid rock called intrusive igneous rock.
Areas of rock can move slowly

compounded by several different factors that include natural (earthquakes, landslides, runoffs from rich metal deposits) and anthropogenic disturbances (improper mining practises, waste disposal, pesticides). (see figure 1) Figure 1. Heavy metal pathway cycles © Dr Mark Hill (2011). Permitted usage According to Shayler et al (2009), certain chemical elements occur naturally in soils as components of minerals, yet may be toxic at some concentrations. Other potentially harmful substances may end up in soils…

The Importance Of Earth Resources

geochemical cycles control the production and availability of Earth resources – e.g. the rock cycle Geothermal energy drives tectonic processes which build mountains, while solar energy creates climate which wears mountains down Throughout this cycle, resources are being produced and brought to the surface to be available for our use By using resources, we can interrupt the natural geochemical cycles – e.g. the carbon cycle Every natural resource we use results in changes to the geochemical cycle that…

emit chemicals that break down rocks and wood. Holiday trees recycled in the woods create shelter for small animals; those deposited in lakes or reservoirs become habitat for fish, or they can be chopped and turned into mulch. Most people are familiar with composting, where food waste is saved and used as fertilizer for gardens. The entire food chain could be said to rely on various forms of recycling. Water is also recycled in nature. This is known as the water cycle. Water on earth evaporates into…

Covid-19 Pandemicic Analysis

Prior to the Covid-19 pandemic, I considered myself an extroverted and disciplined person. However, I was unaware of the many mental blockages I had formed over many years to shield myself from my own thoughts. These thoughts were mostly negative, but they stayed repressed because I made sure to keep myself overly stimulated (school, social media, extracurricular activities, movies/TV, and substance abuse). The framework I created depended on constantly moving my focus to different places in short…
