Science : Rock & Rock cycle

Rock cycle :

magma - igneous rock - sediments - sedimentary rocks - metamorphic rock - magma

• begins with magma, which is molten rock found beneath the Earth's surface

• When magma cools and solidifies, it forms igneous rocks

• igneous rocks could also melt back into magma

• These rocks can be found in various forms such as granite, basalt, or obsidian.

• Over time, weathering and erosion break down igneous rocks into sediments

• These sediments can be transported by wind, water, or ice

• Through compaction and cementation, these sediments become sedimentary rocks. Examples of sedimentary rocks include sandstone, limestone, and shale.

• sedimentary rocks and igneous rocks can both become metamorphic rocks when under heat and pressure

• both sedimentary rocks and metamorphic rocks turn into sediments when weathering and erosion happens

• metamorphic rocks can also melt into magma
