Well, there are 3 types of rocks. One is derived from magmas, ashes and a mixture of both.
These are called Igneous rock (IG-NE-YUS).

Sedimentary rocks are not directly derived from igneous rocks. Sedimentary rocks are formed from the accumulation and cementation of sediments, such as sand, mud, and organic material, through processes like erosion, deposition, and lithification. Igneous rocks, on the other hand, are formed from the cooling and solidification of magma or lava.
Igneous rocks are rocks that form from the cooling of magma or lava, and "igneous" is derived from the Latin word for "fire." Examples of igneous rocks include basalt, granite, and pumice.
The initial rocks (apart from those direct from bolides) would have been volcanic rocks derived from the magma. This would have been in the late Hadean period of the Earth's history.
Magma
igneous rocks
Rocks are formed when magma cools and solidifies either beneath the Earth's surface (intrusive igneous rocks) or on the surface (extrusive igneous rocks). As the molten magma cools, it crystallizes and hardens into solid rocks like granite or basalt.
Igneous rocks form as a result of cooling magma. As the magma cools and solidifies, it forms rocks such as granite, basalt, and obsidian. The size of the mineral crystals in the rock is determined by the rate of cooling.
Intrusive igneous rocks are formed by magma. Magma can also cause the contact metamorphism of rock that it is intruded into.
Gabbro is an igneous rock that forms from the slow cooling and crystallization of magma beneath the Earth's surface. While lava is molten rock that flows on the Earth's surface, gabbro forms from magma that solidifies underground.
No. It's the Metamorphic rocks that melt and become magma.
Intrusive igneous rocks are formed by the cooling of magma.
