Question
Describe how each rock type is formed: Igneous Sedimentary Metamorphic
Solution
-
Igneous Rocks: These rocks are formed when magma (molten rock deep within the earth) cools and hardens. This can happen either on the surface of the earth (extrusive igneous rocks), where the magma cools quickly, or beneath the surface of the earth (intrusive igneous rocks), where the magma cools slowly. Examples of igneous rocks include basalt and granite.
-
Sedimentary Rocks: Sedimentary rocks are formed through the accumulation of sediments. These sediments can come from other rocks that have been weathered and eroded, or from the remains of plants or animals. Over time, these sediments are compressed and harden into rock. This process often occurs in layers, which is why sedimentary rocks often have a layered appearance. Examples of sedimentary rocks include sandstone and limestone.
-
Metamorphic Rocks: Metamorphic rocks are formed when existing rocks (either igneous, sedimentary, or other metamorphic rocks) are subjected to high temperatures and pressures, causing physical or chemical changes. This process, known as metamorphism, does not melt the rock but instead transforms it into a denser, more compact rock. Examples of metamorphic rocks include marble and slate.
