What are the properties of water, and how do they to sustain life on earth?

The main property of water that helps sustain life on earth is that water has. a high specific heat. This causes water to gain heat very slowly.

Specific heat is the amount of heat required to raise the temperature of water by one degree Celsius. Specific heat of water is 4, 186 joules /gram Celsius, and it is higher than that of a metal and of any other common substance.

Due to this, water resists tendency to evaporate or to vaporize and  therefore plays the crucial role of stabilizing temperatures on earth for terrestrial life and at the same time enabling aquatic organisms to maintain relatively constant internal temperatures.

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 !
