Answer:
A, F- Igneous rocks
B, D- Sedimentary rocks
C, E- Metamorphic rocks
Explanation:
Igneous rocks are the rocks that form when magma undergoes crystallization below or on the surface of the earth. When the rate of crystallization is very high, it does not get enough time to form crystals, whereas a shiny glass-like surface is formed throughout the rocks. For example, Basalt, Granite, Syenite.
Sedimentary rocks are those that are formed from the compaction and lithification of sediments. They are weaker rocks in comparison to the igneous and metamorphic rocks because the sediments are easily weathered and eroded by agents such as wind, water, and ice. For example, Sandstone, Shale, Limestone.
Metamorphic rocks are those rocks that are formed from the pre-existing sedimentary, metamorphic or igneous rocks. They are formed when rocks experience high pressure and temperature conditions. They are a very hard type of rocks. For example, Schist, Gneiss, Quartzite.
