What is above the topsoil and how does it form?
Above the topsoil is the subsoil, which consists of a mixture of clay, minerals, and organic matter. This layer forms as water carries minerals and nutrients down from the topsoil, depositing them in the subsoil layer. This process usually takes hundreds to thousands of years.
What word describes the removal of minerals from topsoil or rocks by water that filters down through the soil?
The word is "leaching." It refers to the process where water removes minerals from topsoil or rocks as it passes through them, resulting in the minerals being carried away from the original location.
What process moves minerals into the B horizon?
The process that moves minerals into the B horizon is called illuviation. It involves the movement of dissolved minerals from the A horizon or the topsoil downward into the B horizon or subsoil through the percolation of water.
Where does topsoil originate from?
Topsoil is formed from the weathering and decomposition of rocks and organic matter over time. It originates from a complex process involving the breakdown of minerals, plant material, and living organisms, which gradually forms a fertile layer on the Earth's surface.
What is stratum below topsoil?
Below the topsoil is the subsoil layer. This layer typically contains less organic matter and nutrients compared to topsoil. It often consists of weathered rock, clay, and minerals that are broken down from the topsoil layer above.

Which soil layer is richest in humus and minerals?
topsoil
What is the washing away of minerals?
The washing away of minerals is a process known as leaching, where minerals in the soil are dissolved and carried away by water. This can lead to a depletion of essential nutrients in the soil, impacting plant growth and soil fertility. Management practices such as adding fertilizers or organic matter can help replenish lost minerals.

What is beneficiating?
brifely explain the iron ore benification process
Which layer of soil is high in organic material but relatively low in minerals?
Topsoil.
What is stratum below topsoil?
Below the topsoil is the subsoil layer. This layer typically contains less organic matter and nutrients compared to topsoil. It often consists of weathered rock, clay, and minerals that are broken down from the topsoil layer above.
Topsoil is made up of what?
it is made up of decomposed bits of minerals from the humos layer
What is harmful because plants do not grow well when topsoil has been lost?
You probably are thinking about soil erosion. When the topsoil and minerals wash away, it is harder for plants to grow.
