Question

Which of the following BEST summarizes the soil progression from top to bottom?

There is a decline in the amount of nutrients and a decrease in solidification.
There is an incline in the amount of nutrients and an increase in solidification.
There is an incline in the amount of nutrients and a decrease in solidification.
There is a decline in the amount of nutrients and an increase in solidification.

Answer 1

There is a decline in the amount of nutrients and an increase in solidification.

Step-by-step explanation:

The correct answer is There is a decline in the amount of nutrients and an increase in solidification. The top layers of soil are rich in nutrients but are very malleable. As the layers go deeper into the Earth, the nutrient content drops while the soil becomes harder.

Answer 2

There is a decline in the amount of nutrients and an increase in solidification.

Step-by-step explanation:

There are many layers that constitute the formation of the soil. The layers of the soil are termed as horizons. The upper layer or the topsoil is rich in organic matter. The dead and decaying matter are constituted in the upper layer. Below each layer the level of organic material decreases. The bottom layer is the bedrock. The soil becomes hard and tough from top to bottom.
