How does groundwater become polluted?

a.
pollutants mixed with water pass through permeable layers above the aquifer.

b.
factories dump their waste directly into aquifers.

c.
refuse infiltrates the water table when garbage is dumped.

d.
all of the above

Option D, all of the above, is the correct answer.

The groundwater is the rainwater found beneath the surface of the earth and in the cracks of mineral sediments. The groundwater is commonly less valuable, more convenient. The groundwater similarly to the public water also open to pollutants. This contamination of water reserves occurs when leakage of substances arises during the artificial processes such as drilling, boring, substances, and road salts and when garbage is dumped into the water reservoirs etc. Consequently, pollutants get mixed with water and pass through the permeable layers.

d concave shape of wave rock

explanation:

the concave shape of wave rock is a very good evidence that supports the evolution of earth due to chemical weathering. if we talk about structure of   wave rock, studies have estimated that it is around 2.7 billion years old. it also serves as the foundation of evidence that it was the place where australian continent began to form.

how the structure of wave rock was created?

studies suggest that structure of wave rock was created when the surrounded area was started to weather due to which deposition of material started on the part of land which now contains wave rock.

the structure of wave rock is considered to be one of the best-known landforms in australia. at the height of around 15 cm, there can be found flared slopes which formulate the margins of hyden rock. it is now assumed by geologists that wave rock was created by subsurface water-induced weathering and not by glaciers, waves or wind.

due to deposition of material over the period of long time, the wave rock became tougher and tougher due to weathering from surrounding terrain. this makes it a physical evidence that supports   the evolution of earth due to chemical weathering.

hope it !
