The radioactive decay of uranium and thorium minerals in igneous rocks such as granite can cause the release of the gas Radon which is dangerous to humans.
The breakdown (anaerobic decay) of biological materials in soils and rocks at shallow depths can also produce methane gas which can be explosive or potentially cause asphyxia by displacement of oxygen at high concentrations.
Radon gas is a naturally occurring radioactive element which can be produced by the decay of radium (which in turn is part of the decay chain of uranium) present in granitic rocks and shales and also soils derived from these two rock types.
which element is not released in the atmosphere
Soil is neither an element nor a compound. It is a mixture.
The lightest naturally occurring actinide on Earth is thorium, which has the atomic number 90. It is a naturally occurring radioactive element found in small amounts in soil and rocks.

Silicon is the main element found in sand, rocks, and soil. It is commonly found in the form of silicon dioxide, which is the main component of sand and rocks.
Soil is neither an element nor a compound. It is a mixture.
Carbon is an element. It is part of oceans, air, rocks, soil and all living things.

The minerals get into the soil by erosion of the rocks.
To effectively sift rocks out of soil, you can use a sieve or a screen with small holes to separate the rocks from the soil. Simply pour the soil and rocks onto the sieve and shake it gently to allow the soil to fall through while the rocks remain on top. Repeat the process until most of the rocks are removed from the soil.
soil comes from rocks. that's all i know
