Answer:

Surface tension is the result of water molecules pulling inward with a strong attractive force. This attractive force brings the molecules on the surface of the water close together and causes the surface of the water to be drawn toward the water molecules beneath the surface. Since there are no water molecules above the surface, there are uneven forces. This causes surface tension, allowing the coin to float on the water’s surface.

Why Are aquifers important to our freshwater supply? 5TH GRADE ANSWER c:
ANEK [815]

Explanation:

Aquifers are porous and permeable formations that stores ground water. The ground water system is made up of mostly fresh water.

  • An aquifer acts as a reserve for ground water in the environment.
  • By passing through different formations, water that recharges them are purified.
  • This makes them fresh and mostly free from salt intrusion

An aquifer is able to store this fresh water and it is is good prospect for sourcing ground water.
