The last layer of soil to form a horizon is called Horizon C. This layer is often referred to as the parent material, as it is made up of weathered rock fragments that have not yet fully decomposed into soil. Horizon C is the layer closest to the bedrock and has the least amount of organic matter.
The O horizon forms last in the soil profile as it consists of organic material like decaying leaves and plant matter on the soil surface. It is considered the top layer of the soil profile and is constantly being replenished by new organic material entering the system.
The O horizon is the topmost layer of soil that forms last. It consists of organic matter in various stages of decomposition, such as fallen leaves and plant material.
Soil begins to form in the top layer of the Earth's crust, known as the "A horizon" or topsoil layer. This layer contains a mixture of organic matter, minerals, water, and air that supports plant growth.
The first layer of soil is called the O Horizon, it is made of primarily humus. The second layer is the A horizon, this is the topsoil. Then there comes the E layer which is the eluvation layer. Next comes the B horizon which is the subsoil, then there is the C horizon which is the regolith, then the final layer is the R layer which is bedrock.
The soil horizon that has the darkest and richest soil is usually the topsoil layer, known as the A horizon. This layer contains a high amount of organic matter and nutrients, making it ideal for plant growth.

Dead leaves form the top layer of soil known as the organic or O horizon. This layer is rich in organic matter and essential nutrients for plants. As dead leaves decompose, they contribute to the soil's fertility and health.
The A horizon is the top layer of soil, where most organic matter accumulates and plant roots grow. The R horizon is a layer of partially weathered bedrock underneath the soil layers. The A horizon develops from the weathering of the R horizon over time.
