Fossils are not found in the soil. They are found in layers of rock after time.
It is highly unlikely to find dinosaur bones in your backyard. Dinosaur bones are typically found in specific geological formations and require specialized knowledge and equipment to excavate and identify. It is more common to find fossils of marine organisms or plants in backyard soil.
Dinosaur bones can become radioactive due to the presence of trace amounts of radioactive elements, such as uranium and thorium, in the surrounding rocks and soil where the bones are buried. Over time, these radioactive elements can seep into the bones and cause them to become radioactive themselves.
bedrock
Soil is found in the topmost layer of the Earth's crust, known as the "soil layer" or the "pedosphere." It typically ranges from a few centimeters to a few meters in thickness and is essential for supporting plant life and sustaining ecosystems.
The A horizon.
The layer of solid rock found under all soil is known as bedrock. It serves as a foundational layer that underlies all soil and provides stability and structure to the Earth's surface.
topsoil.
The layer of soil is called the topsoil, which is the uppermost layer of soil that contains most of the organic matter and nutrients that plants need to grow. It is typically the darkest and richest layer of soil, where most plant roots are found.
soil erosion
bedrock
Soil is found in the outermost layer of the Earth's crust, known as the "lithosphere." It is a mixture of mineral particles, organic matter, water, and air that supports plant life.
Topsoil is found in the uppermost layer of soil, typically the top 2-8 inches. It is rich in organic matter, nutrients, and microorganisms, making it crucial for plant growth and agriculture.
