Molten substances that appear at the surface of the Earth include lava, which is molten rock that flows out of volcanoes during eruptions, and magma, which is molten rock beneath the Earth's surface. These molten substances can solidify into igneous rock as they cool.

rock cycle
A piece of rock is not considered a compound but rather a mixture of different minerals. Each mineral in the rock is typically a compound composed of different elements. Compounds are substances composed of two or more elements chemically bonded together in specific proportions, whereas mixtures are physical combinations of substances.
Obsidian is an igneous rock. Rocks are not man-made. Man-made substances that are similar to rock include concrete and cement.

The five basic substances involved in the rock cycle are magma, igneous rock, sedimentary rock, metamorphic rock, and mineral crystals. These substances undergo processes such as melting, cooling, weathering, and metamorphism to transition between different rock types in the cycle.
Plants which make substances that break down rock are called lichens. Lichens are known to release acids that break down rocks.

The rock in the asthenosphere is under immense pressure from the overlying rock. Increased pressure raises the melting point of most substances.
Rock is made up of two main substances -Platapus feces :99% -Sooper noodles:1%
This process is called leaching. Water passing through rock or soil can dissolve minerals and other substances, carrying them away with the moving water.
