Any mineral that you can think of that is under ground!
The ones i know right now are onyx, and other stuff!
erosion but it would take thousand of years
Igneous rock forms from the cooling of magma. This forms a rock that is uniform in composition, and sometimes contains air pocketed texture from the process of cooling. Sedimentary rock is formed of small bits of dirt and stone that bind together after they settle as sediment. This rock is usually distinguishable by the flecks of different types of rock and dirt. Metamorphic rock is any type of rock that is transformed by heat, pressure, or chemical changes. It often becomes denser and smoother than the rock from which it changed.
there all rocks igneous rock, metamorphic rock, and sedimentary Rock
A rock is amineral
Weathered rock provides the material for soil.
Basalt, a fine-grained igneous rock, typically produces the deepest soil due to its high mineral content and rapid weathering process. The minerals in basalt, such as feldspar and pyroxene, break down efficiently, contributing to fertile soil formation. Additionally, its dark color helps absorb heat, promoting biological activity that further enhances soil depth and quality. Overall, basalt's properties make it conducive to generating rich, deep soils.
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.
igneous rock
The deepest layer in soil is called the parent material or bedrock. This layer is comprised of solid rock and is located beneath all other soil horizons.
pumice...i think
Soil can be formed from the erosion and deposition of any kind of rock: igneous, sedimentary, or metamorphic.
The deepest soil horizon is typically the C horizon, also known as the "parent material." This layer is composed of unweathered rock or partially weathered rock from which the upper layers of soil are formed. Below the C horizon lies the bedrock, which is not considered a soil layer but rather the solid rock underlying the soil profile.
obsidian? i think?
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.
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.
The igneous rock that, when weathered, could produce sediment composed of potassium feldspar, quartz, and amphibole is granite. Granite is a coarse-grained rock primarily composed of these minerals, and upon weathering, it breaks down into smaller particles, contributing to sediment in the environment. This sediment can then be transported and deposited, forming sedimentary rock or contributing to soil formation.
No that is a metamorphic rock
