THE ROCK CYCLE

1. THE ROCK CYCLE Alexis Piña Giovanni Arias Leonardo Leyton Ilan Machel Daniel Peralta

2. INTRODUCTION The rock cycle is a geological process that describes the continuous transformation of the three main types of rocks: igneous, sedimentary and metamorphic. This cycle is driven by the Earth's internal dynamics, such as the movement of tectonic plates, and by external processes, such as erosion and weathering.

3. EXAMPLE

4. Igneous Rock They are formed from the cooling and solidification of magma or lava. When magma cools below the Earth's surface, intrusive igneous rocks (such as granite) form. When lava cools at the surface, extrusive igneous rocks (such as basalt) form.

5. Sedimentary Rock They are formed from the compaction and cementation of sediments, which can be fragments of other rocks, minerals and organic remains. Erosion and weathering processes break existing rocks into particles that are transported and deposited in different environments. Over time, these sediments compact and form sedimentary rocks (such as sandstone or limestone).

6. Metamorphic Rock They are formed when igneous, sedimentary or even other metamorphic rocks are subjected to high pressures and temperatures, which causes changes in their mineralogical and textural structure. This process, called metamorphism, does not involve the fusion of the rock, but rather a solid transformation. Examples of metamorphic rocks include marble (which forms from limestone) and shale (which forms from clayey sedimentary rocks).

7. FINAL CONCLUSION The rock cycle is important because of the information it can give us such as our history, data from the geological past, it helps us understand phenomena that happen on our earth and makes us understand the history of each of the rocks and understand the their origin and know the internal processes.
