The amount of water a body requires for survival is dependent upon the climate and the individual’s level of physical activity. select the best answer from the choices provided t f

True,  

The amount of water required to support healthy living and life is dependent on both the climate and the amount of physical activity of an individual.  

People living in extreme cold climate may not require as much water as required by people living in extreme hot climatic conditions. During hot climatic conditions, the loss of water from our body increases on account of excessive sweating and thus the water requirement increases. The same is the case with individual doing high physical activities which accounts to increased sweating, along with high rate of breathing which require more cellular respiration and fluid consumption to compensate the loss of fluid and energy in the body.

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.
