Answer:
Phosphorus moves in a cycle through rocks, water, soil and sediments and organisms. Over time, rain and weathering cause rocks to release phosphate ions and other minerals. This inorganic phosphate is then distributed in soils and water. Plants take up inorganic phosphate from the soil.

Answer:
Explanation:
All things — living and nonliving — are made of matter, and all matter is composed of tiny particles called atoms. Atoms combine together to form molecules. Atoms of different types are called elements.
Its 4.375 but you would probably round it to 4 or 5
The makeup of air/atmosphere,can change the pH.
For example, when the USA relied heavily on coal fired electric generating plants the air became acidic.
This polluted air would drift or be blown around the continent. When the rains came, “acid rain” would overwhelm many trees and other vegetation, harming it.
See pasted in below:
Normal, clean rain has a pH value of between 5.0 and 5.5, which is slightly acidic. However, when rain combines with sulfur dioxide or nitrogen oxides—produced from power plants and automobiles—the rain becomes much
