1. Which of the following explains the variable that would be the best for students to measure to determine the direct impact of soil erosion caused by the construction project on the river?

Turbidity

Explanation:

The variable that is the best to help a student to measure in order to know the impact of soil erosion which was caused by the construction project that took place on the river TURBIDITY will be the best variable reason been that TURBIDITY help to measure the cloudiness in a water which means that the higher the cloudiness in a water the higher the TURBIDITY and Secondly a situation where their is a high soil erosion it will often lead to reduction in clarity of water which is why TURBIDITY is a vital tool to help measure all the particles in water which a physical eyes cannot see.

located offshore, in the arctic and pacific oceans

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 !
