Here is a quick explanation of every phase in the rock cycle: 1. Igneous rocks: These rocks are shaped with look at this site the solidification of molten magma or lava. When magma cools and crystallizes beneath the Earth’s surface area, it varieties intrusive or plutonic igneous rocks. Samples of intrusive igneous rocks consist of granite and diorite. When lava reaches the Earth’s surface area and cools speedily, it sorts extrusive or volcanic igneous rocks. Samples of extrusive igneous rocks include basalt and obsidian. 2. Sedimentary rocks: These rocks are formed from your accumulation and compaction of sediments. Sediments are smaller particles of rock, minerals, and natural and organic make any difference which are carried by wind, water, or ice.
