The picture shows an example of contour plowing. how does this method farmers? a. it reduces soil erosion. b. it reduces landslides. c. it reduces flooding. d. it increases crop yield. e. it reduces pollution.

Answer is: A. It reduces soil erosion.

Contour plowing or contour farming is the plowing and planting across a slope following its elevation contour lines.

This lines create a water break which reduces the formation of rills during rains, because lines let more time for the water to settle (stay) into the soil.

Contour plowing is effective on slopes with between 2% and 10% gradient.

The correct answer is option A which is It reduces soil erosion.

explanation:

let the different atoms be x and y. each with four protons and same mass will be represented as follows.

mass number is number of protons + number of neutrons.

            and  

since, it is given that one has a negative charge while the other is neutral. therefore, there will be increase in number of protons and the atom will be represented as follows.

according to periodic table, mass number of beryllium is 9 and it has atomic number 4 so, the atoms will be and .  

the protons and neutrons will be located inside the nucleus whereas the electrons will be revolving around the nucleus.
