Answer:
The thermocline is a layer in the ocean that represents:
<u> Density change due to temperature.</u>
Explanation:
A thermocline is a thin distinctive layer in a large body of fluid which is exactly located between warmer mixed water at the top of ocean surface and cooler deep water at the bottom of ocean surface. Salinity is defined as the total amount of salt dissolved in water.
The water in the ocean or sea forms into layers according to density. Water with high density sinks at the bottom while water with low density sits on the top. And the density of water changes with salinity and temperature. Higher salinity leads to higher density, and the water changes rapidly with depth.

The advantage of using passive or active solar systems was these systems release low amounts of carbon dioxide or other pollutants. Thus, Option C is the correct statement.
<h3>What is the benefit of using Passive or active solar systems?</h3>
One of the best reasons to use effective solar technology is to reduce your energy bills. Active solar systems can include expensive hardware, and Passive solar systems may create the cost of renovating your home, but a reduction in your utility bills will ultimately outweigh the costs.
Thus, Option C is the correct statement.

Answer:
Sampling
Explanation:
Sampling is a statistical procedure in which a selected number of observations is used to represent the whole observation. When we take an area and we use the population to estimate that of other areas or the whole population, we are simply sampling. Sampling is very important to some specific forms of observations. Sampling can be done randomly or in a systematic way. The goal of sampling is using the part to represent the whole.
Answer: Hypothesis: <u>is a supposition or proposed explanation made on the basis of limited evidence as a starting point for further investigation.</u>
Theory: <u>a supposition or a system of ideas intended to explain something, especially one based on general principles independent of the thing to be explained.</u>
Both: A hypothesis is either a suggested explanation for an observable phenomenon, or a reasoned prediction of a possible causal correlation among multiple phenomena. A theory is always backed by evidence; a hypothesis is only a suggested possible outcome, and is testable and falsifiable. ...In science, a theory is a tested, well-substantiated, unifying explanation for a set of verified, proven factors. A theory is always backed by evidence; a hypothesis is only a suggested possible outcome, and is testable and falsifiable.
