If two water samples of equal mass had equal salinities, which sample would be more dense: water sample a, which has a temperature of 25°c, or water sample b, which has a temperature of 14°c?

The 14°C sample is more dense than the 25°C sample.

Explanation:

Warm water rises, cooler water falls. Warm water is less dense than cooler water. The actual density of water changes about .4% as the water temperature changes from near zero at 0°c up to about 30°c. That may not sound like much. However, that is enough density change for cold water to flow below warm water. This can have an impact on ocean currents and other phenomena in the ocean.

The sample water would be more dense.

Explanation:

As it has been proved that the density of a water depends on its salinity and its temperature.  The cold water is denser and it will be less dense when it is warm. The density is dependent on the salinity too.

So, it is evident that among the two mentioned samples the sample B with the temperature of 14 degree will be denser than the sample of salty water that has 25 degree temperature.

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 !

some of your causes might be acidic rain or natural wildfires that cause the parks to be degraded

hope this any more questions i am here plz mark brainliest
