Biologically, Chemically and Mechanically.
Three main ways and are classified accordingly. Igneous rocks form from molten material called magma.
Rocks are formed through the processes of cooling and solidification of molten material (igneous rocks), through the compaction and cementation of sediments (sedimentary rocks), and through the alteration of existing rocks due to heat, pressure, or fluids (metamorphic rocks).
Igneous, sedimentary, and metamorphic rocks are differentin their method of formation. Igneous rocks solidify from melt, sedimentary rocks form from the lithification of sediments, and metamorphic rocks form from the application of heat and/or pressure over time. These rocks are alike in some ways, too, however. Igneous, sedimentary, and metamorphic rocks can share compositions -- they can be composed of cominations of biotite, calcite, quartz or other minerals. Their origin can also be shared. For example, a composite volcano has all three types: a sedimentary rock formed from welded pyroclastics, called welded volcanic tuff, piles up on the slopes. Lava solidifies on the slopes as well, forming igneous rocks. Inside the volcano, solid rock is exposed to heat but doesn't melt. This rock is transformed into metamorphic rock.
there are several ways such as heat & pressure, melting, chemical weathering, compression, compaction & cementation, but it depends on the kind of rock it is for what process it has to go through. -Cutegirl99
No. Not directly at least. Volcanic rock is extrusive igneous rock. Sedimentary rock is formed from sediment weathered out of pre-existing rocks that has been deposited and turned back into stone. Some of this sediment can come from volcanic rocks.

Sedimentary rocks are made up of materials that were once part of another rock. Most sediments are deposited on ocean floors or at the bottom of rivers and lakes.Clastic sedimentary rocks form from layers of sediments. Pressure causes the water around the sediments to be squeezed out and the sediments are cemented together.
Sedimentary rock is one of the three main rock groups (along with igneous and metamorphic rocks) and is formed in three main ways-by the deposition of the weathered remains of other rocks (known as clastic sedimentary rocks); by the deposition of the results of biogenic activity; and by precipitation from solution. Sedimentary rocks include common types such as chalk, limestone, sandstone, and shale. :)
The three types of naturally formed rock formations are igneous, sedimentary, and metamorphic rocks. Igneous rocks form from the cooling of molten magma, sedimentary rocks are created from the accumulation and cementation of sediment, and metamorphic rocks are formed from the alteration of existing rock through heat and pressure.

Sedimentary rocks are formed as a result of deposition of materials at the surface of the Earth or within water bodies.
