Winds often blow loose topsoil away, causing erosion. Planting grass or trees on the soil can prevent this erosion. Which of the following best describes how this solution works?
A.
The leaves of grasses and trees anchor the soil to the ground and prevent it from blowing away.

B.
Grasses and trees create new soil that replaces the soil lost to the wind.

C.
The dead remains of grasses and trees cement the soil to the ground and prevent the wind from blowing it away.

D.
The roots of grasses and trees anchor the soil and prevent it from blowing away.

carbohydrates: (starches and sugars) composed of carbon, hydrogen, and oxygen.

lipids: (fats, oils, and waxes) are made of carbon and hydrogen atoms.

nucleic acids: contain hydrogen, oxygen, nitrogen, carbon, and phosphorus. they are polymers of nucleotides. a nucleotide has three parts, a 5-carbon sugar, a phosphate     (-po⬇️4) group, and a nitrogenous base.

proteins: made up of nitrogen, carbon, hydrogen, and oxygen. they are polymers of amino acids.

1. loamy sand is about 80% sand with 10% clay and defined mostly by sand particles with some clay to provide structure and fertility. the sand particles are easily visible and the soil holds structure but breaks apart easily.

2. scott sand can improve his soil quality by incorporating more silt and organic matter into the soil. peat moss and organic matter can also be incorporated.
