Answer:
Option B
Explanation:
The higher the solute concentration the higher is the density of the solution. Hence, water with high salinity will have high density.
Hot water has energized atoms and molecules which increase fluidity of water as viscosity is reduced. On the other hand cold water has high viscosity and hence it is denser than hot water.
Thus, Water having high salinity and low temperature will be more dense.

Answer:
The map in question is a topographical map.
Explanation:
There are numerous different types of maps and every one of them has its own special purpose. One of the most commonly used types of maps is the topographic map. This a type of map where the focus is on the relief, or rather it gives us a good representation of the sloping and elevation of the mapped area.
In this case, we have a national park, represented on a map that uses lines to show sloping and elevation. This is a typical example of the topographic map as the map is showing exactly that, the topography, or relief of the area. The lines that are mentioned are contour lines, which are lines specialized specifically for the purpose of reprsenting relief as better as possible.
Answer:
C. a topographical map
Explanation:
Topographic maps are reference maps that show the shape of Earth's surface. They usually do this with lines of equal elevation known as "contour lines", but elevation can also be shown using colors (second map), color gradients, shaded relief and a number of other methods.
