Igneous rock forms from the cooling of magma. This forms a rock that is uniform in composition, and sometimes contains air pocketed texture from the process of cooling. Sedimentary rock is formed of small bits of dirt and stone that bind together after they settle as sediment. This rock is usually distinguishable by the flecks of different types of rock and dirt. Metamorphic rock is any type of rock that is transformed by heat, pressure, or chemical changes. It often becomes denser and smoother than the rock from which it changed.
Igneous Rocks are usually black and smooth because they ate formed by heat, sedimentary rocks are usually layered in color.
Igneous rocks are made by melted rock materials that cool and harden.Which the answer would be there formed that way and no other rock is formed that way.
Igneous, metamorphic, and sedimentary are the three types of rocks. Sedimentary is formed when layer of mud or silt build up gradually. Igneous is formed when molten magma cools. Metamorphic is formed when a type of rock changes to another type
You can tell rocks apart by its hardness, cleavage, and streak

I'm going to tell you right now there are a lot more than three rocks on earth. However, there are only three basic TYPES of rocks, and those are Sedimentary, Igneous, and Metamorphic.
Basically a bunch of rocks come together( are pressed together by heat and pressure) in a process called Lithification , those rocks can be either Sedimentary or Igneous rocks.
Understand that metamorphic rocks are those that have changed in some way by heat or pressure or both. Sedimentary rocks are formed from sediments and igneous rocks are formed by fire. When these rocks change again, they become metamorphic. Marble is one type of metamorphic rock.Look at the way the grain are formed. In schist rocks, you can see that the layers and the grains all go the same way. Warning Metamorphic rocks are difficult to classify because different amounts of heat or pressure to the same rock can look different.

Metamorphic rocks are used in counter tops, building construction, paving, sculpture, and jewelery.We may use it for countertops such as marble and Slate.
