Different densities have to have a reason - different pressure and/or humidity etc. If there is a different pressure, there is a mechanical force that preserves the pressure difference: think about the cyclones that have a lower pressure in the center. The cyclones rotate in the right direction and the cyclone may be preserved by the Coriolis force.
If the two air masses differ by humidity, the mixing will almost always lead to precipitation - which includes a phase transition for water etc. It's because the vapor from the more humid air mass gets condensed under the conditions of the other. You get some rain. In general, intense precipitation, thunderstorms, and other visible isolated weather events are linked to weather fronts.
At any rate, a mixing of two air masses is a nontrivial, violent process in general. That's why the boundary is called a "front". In the military jargon, a front is the contested frontier of a conflict. So your idea that the air masses could mix quickly and peacefully - whatever you exactly mean quantitatively - either neglects the inertia of the air, a relatively low diffusion coefficient, a low thermal conductivity, and/or high latent heat of water vapor. A front is something that didn't disappear within minutes so pretty much tautologically, there must be forces that make such a quick disappearance impossible.
The order from closest to furthest away include the following:
<h3>What is Kuiper belt?</h3>
This is the region which ends around 50 AU from the Sun and has the presence of the scattered disc in its outer surface.
The Oort cloud has a distance of between 2,000 and 10,000 thereby making it the farthest which is why the correct order is B, A and C.

The experiment was well designed.
<h3>What is an experiment?</h3>
An experiment is used to determine cause and effect relationships. We know that in this case, the research is aimed at being able to obtain the relationship that exists between the amount of nitrogen in the soil and the production of tomatoes per plant.
As we could see, the experiment includes a control that serves as a baseline for determining the validity of the results. Further more, the sunlight, water and soil were held constant. The experiment was even repeated further south to verify the results.
Based on a careful review of the experiment, the experiment was well designed.

Answer:
<em>Answer A. Fission, steam, turbine, electricity, cool water</em>
Explanation:
<u>Nuclear Energy Production
</u>
Nuclear energy is produced by splitting uranium atoms in a process called fission. This generates heat and it's managed to produce steam, which later is used by a turbine generator to generate electricity. The heat must be taken out of the system, so a cooling process, usually involving water is the final step.
Because nuclear power plants don't burn fuel, they are known as clean energy sources.
