1. The two types of igneous rocks are intrusive and extrusive. Intrusive are rocks that form underground. Magma is underground so the intrusive rock will most likely form from magma. Some examples of intrusive rocks are diorite, granite, and gabbro.Extrusive rocks are rocks that form above ground, probably from lava. Some examples would be obsidian and pumice.
2. The two types of metamorphic rocks are foliated and non- foliated rocks. foliated rocks are metamorphic rocks that have a layered or banded structure. non-foliated rocks aren't banded. some examples of foliated and non-foliated rocks are gneiss, slate, quarzite,and marble.
3. Two of the three main types of sedimentary rocks are clastic which are formed by mechanical weathering debris. the other is chemical whic is formed by dissolved materials the precipitate from solution. Some examples of clastic and chemical sedimentary rocks are snadstone, shale, limestone, and rocksalt.
