Because there are different types of magma and different pathways for that magma to cool.
Magma underground may differentiate and form different intrusive igneous rock. Magma from the magma body may erupt, cool, quickly, and form fine-grained extrusive igneous rock, or partially remain underground and form intrusive igneous rock. The type of igneous rock formed from the magma body will largely depend on whether or not it is erupted, and the speed of its cooling.
When extensive igneous rock is broken down by weathering, it is likely to form sedimentary rock. The weathering process breaks the igneous rock into smaller particles, which can then be transported and deposited. Over time, these sediments can accumulate and compact, eventually lithifying into sedimentary rock. This transition illustrates the rock cycle, where different rock types can transform through geological processes.
Extrusive igneous rock is formed from the solidification of lava.Intrusive igneous rock is formed from the solidification of magma.
The two main types of igneous rock are intrusive and extrusive. Intrusive rocks form underground and have larger crystals due to slower cooling. Extrusive rocks form on the Earth's surface and have smaller crystals due to rapid cooling.

Igneous rock is called a "mother rock" because it is the primary rock type from which other types of rocks are formed. When igneous rocks undergo weathering and erosion, they break down into sediments that can be lithified to form sedimentary rocks. Additionally, igneous rocks can be subjected to heat and pressure, leading to their metamorphism into metamorphic rocks. This process of igneous rocks being the origin or "mother" of all rock types is why they are referred to as such.
Some types of igneous and sedimentary rocks can form on Earth's surface.
Metamorphic rock can become igneous through a process called melting. When metamorphic rock is subjected to extreme heat, it can melt into magma. Once this magma cools and solidifies, it crystallizes to form igneous rock. This transformation highlights the rock cycle, where different types of rocks can change from one form to another over geological time scales.
A single magma with a unique chemical composition can form different types of igneous rock depending upon which type of magma it is. Magma can either erupt through the surface of the earth and form igneous rocks when it cools and crystallizes on the surface, or it can crystallize at depth in the earth. Each type of eruption of the same magma will produce different types of rock.
igneous metamorphic and sedimentary
Granite and basalt are the most common types of igneous rock. Igneous rock types, or classifications, also include those that are intrusive and extrusive. Intrusive igneous rock is formed from the solidification of slow cooling magma below the surface. Extrusive igneous rock is formed for the solidification of rapidly cooling lava at or near the surface.

magma cools to form igneous rock
Extrusive igneous rock is one of two different types of igneous rocks. The other kind is intrusive igneous rock. Intrusive igneous rock is formed when magma in Earth's lithosphere cools and hardens. Extrusive igneous rock is formed when lava on Earth's surface cools and hardens.
