perlite
Igneous rock soil mixes typically consist of volcanic rocks such as basalt, andesite, or rhyolite. These rocks weather over time to produce mineral-rich soils with good drainage and fertility. Igneous rock soils are commonly found in areas with volcanic activity.
pumice...i think
Pumice is a common type of Igneous rock used in soil mixes. It is lightweight and porous, which helps improve aeration and drainage in soil. Pumice is also resistant to decomposition, making it a long-lasting addition to soil mixes.
obsidian? i think?
Yes,igneous rocks are also changed into soil.But they take millions of years to change into soil
sedimentary rocks
No that is a metamorphic rock
Are meatmorphic rocks and also perhaps soil.
Soils derived from igneous rocks tend to be more fertile than those derived from metamorphic rocks. This is because igneous rocks have a higher mineral content that can break down into nutrients essential for plant growth. Metamorphic rocks may have fewer minerals available for plant uptake, resulting in less fertile soil.
igneous rocks
Sedimentary rock is formed when igneous rocks weather to sediments, then the sediments compact to sedimentary rock. When Igneous rocks are subjected to heat and pressure but do not melt, they become metamorphic rock. When igneous rocks are melted they make other igneous rocks.
No all it does is caliboralitate with rocks and it might start hispemideadilitadigerating and mess up your soil.
