Question

Can anybody tell me the conclusion for the igneous rocks

Answer 1

igneous rocks can be classified based on texture and mineral composition. Igneous rocks also can be coarse or fine crystalline and multicolored or glassy. Igneous rock is formed through the cooling and solidification of magma or lava. Igneous rock may form with or without crystallization, either below the surface as intrusive(plutonic) rocks or on the surface as extrusive(volcanic) rocks. he texture is dependent upon cooling environment. !hen magma cools slowly beneath earth"s surface, large crystals form. !hen lava cools #uickly on earth"s surface, tiny crystals form.  on classifing rocks, we can identity by the mineral composition. colour can be used to determine wheteher a rock is rich in silica or metals.
