The Earth is made up of 75% water. Sources such as oceans, lakes, anD rivers have an important role in keeping Earth’s surface insulated and warm. What property of water provides this protection?

The  high specific heat capacity of water.

Explanation:

When there is a need to raise the temperature of a given amount of a substance by a given amount,the amount of heat required is called heat capacity for that substance.Therefore the amount of heat energy required to  raise the  temperature of I g of water by 1 degree is called the specific heat capacity of  water.

This property of water is due to abundant hydrogen bonds in water molecules.These bonds restricts moment of molecule of water,and thus thier diffusion. Thus in order to free these molecules the hydrogen bonds must be heated up to break so that they could gain kinetic energy to escape. This characteristic makes molecules of water to resist wide fluctuations in body temperature.Hence stabilizing the body fluid in living organism

A change in earth temperature is managed by water specific heat capacity because,it takes significant amount of heat for the water to boil,and when there is a need  release heat during cooling this is done slowly with insignificant rise in the earth temperature.,(since 75% of earth is water,)this keeps the earth temperature in a tolerable limits.

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 !

c is the correct answer hope this !
