Read the given paragraph and answer the following questions.

Igneous, sedimentary, and metamorphic rocks constitute the three primary categories of rocks, each formed through different processes. Igneous rocks originate from the cooling and solidification of magma, with their names derived from their composition and crystal sizes. The location of cooling distinguishes them into intrusive, which cool slowly beneath Earth's surface forming large crystals (e.g., granite, diorite), and extrusive rocks, which cool rapidly on the surface resulting in fine crystals or glassy textures (e.g., basalt, obsidian). Sedimentary rocks form through the accumulation and compaction of sediments, which can include weathered rock particles, minerals precipitated from solution, or biological debris, leading to types like sandstone, limestone, and coal. Metamorphic rocks are transformed by intense heat, pressure, and chemical processes below Earth's surface, altering their original structure into new forms with distinct foliated or non-foliated textures, examples being slate, marble, and gneiss. These categories underscore the diverse processes that contribute to the rock cycle, shaping the geological landscape.
