One student suggests using bottled water for washing clothes to conserve water. which of these statements best describes the suggestion made by the student? ) it is practical because it is easy to implement. 2) it is practical because a huge amount of water can be conserved by this method. 3) it is not practical because bottled water costs more than tap water. 4) it is not practical because water use is not reduced by buying water from an outside source.

Using bottled water for laundry to conserve water is not practical. It is not practical because bottled water costs more than tap water. It is not practical because water use is not reduced by buying water from an outside source.

I would say number 4

the correct answer: the index of refraction of the second medium is lower i tried this persons answer and it was wrong this person is lying

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 !
