Answer: -
After rain fall occurs, water accumulates
.
This water is called ground water. This water slowly flows under the ground through the pore spaces in the soil. The water continues to go under the soil till it reaches a certain point where it can no longer go down.
In this region the water slowly accumulates forming a water reservoir called aquifer. The aquifer is a place under the soil which is saturated with water. The upper surface of this zone of saturation is called the water table.

They are more likely to be covalent as covalent compounds usually tend to be radical on the color spectrum with deep purples and blacks and even earwax colored.
d. When aluminum-28 undergoes beta decay, silicon-28 is produced.
Explanation:
When the nuclei of aluminium-28 decays, it produces silicon- 28:
Aluminium ²⁸₁₃Al
Silicon 28 ²⁸₁₄Si
beta particle ⁰₋₁
²⁸₁₃Al → ²⁸₁₄Si + ⁰₋₁
This way, the mass and atomic number are conserved.
Conservation of mass number:
28 = 28 + 0, 28 = 28
13 = 14 -1 , 13 = 13
