What is an aquifer for science class

Explanation:

An aquifer is a layer formed by cracked rocks and the spaces between them and particular types of materials are consolidated among them, like sand and certain fungus and slit etc, which results in underground water flowing into these underground spaces (cavities) continually in less or sometimes more quantity.

Water moves very slowly downwards into them and then eventually it moves out of them into springs and enters into the streams or sometimes this water can also be pulled out by wells. Moreover aquifers are also an important source through which waters of the land enters into the oceans.

answer: the correct answer id option(d).

explanation:

snell's law refraction:

the angle of refraction =

the angle of incidence =

refractive index of air = = 1

refractive index of glycerol = 1.47

from the given options, the most closest answer to 63.72° is 65° of option (d).

this is a good question! i'll do some research and come back when i have the answer!
