they are quartz, mica, feldspar, and calcite.
The four major spheres of the earth are thehydrosphere (made of water)lithosphere (made of rocks)atmosphere (made of gasses)biosphere(comprising all living things)

Four of the metamorphic rocks are gneiss,slate,marble and schist.
they are classified into 3 major kinds of rocksthey are the ;IGNEOUS ROCKS,SEDIMENTARY ROCKS,AND METAMORPHIC ROCKS
The four major rock-forming minerals are quartz, feldspar, mica, and amphibole. These minerals are commonly found in various types of igneous, sedimentary, and metamorphic rocks and make up a significant portion of the Earth's crust.
Each of the rocks form in a different way.
they are both rocks and are heavy sometimes
Igneous Rocks,Sedimentary Rocks,Metamorphic Rocks.
The two major sources of chemically unreacted rocks are igneous rocks and metamorphic rocks. Igneous rocks form from the cooling and solidification of magma or lava, while metamorphic rocks are formed by the alteration of pre-existing rocks through heat and pressure without melting.
volcanic rocks
The four I know of are: gabbro, basalt, peridotite, and dolerite.
Foliation is a characteristic of some metamorphic rocks.
