Lowlands is a name commonly applied to places where there are no mountains. If there were mountains in a place, they wouldn't call it lowlands.
Mountains are colder than lowlands because as altitude increases, the air pressure decreases, causing the air to expand and cool. Additionally, mountains are often snow-capped because they receive less direct sunlight due to their elevation and can experience quicker weather changes.
Mountains are colder than lowlands because as air rises, it expands and cools. This cooling effect, known as adiabatic cooling, causes mountain regions to have lower temperatures compared to lowlands at the same latitude. In addition, mountains receive less direct sunlight due to their height, and their higher elevation means they are located above the inversion layer where temperature decreases with altitude.

Gases are less dense than solids.
A wooden block can be less dense than water.
Ice is less dense than water
Due to altitude the higher you go the less dense air becomes. Since mountains are up so high the air is less dense than it is at sea-level. Air's density is highest at low elevations but decreases as elevation increases.
Ammonia is less dense than air at room temperature and pressure. This is why ammonia gas rises in air.
Oil IS already less dense than water.
Water is less dense than any of the other materials listed.In order of density from least to highest:Water (least dense)GraniteBasaltIron (most dense)
Yes, saliva is less dense than oil. Saliva is composed primarily of water, whereas oil is made up of non-polar molecules that are less dense than water.
Your question is hard to answer for you have not made it clear what you are asking. The term "is less dense than?" is not a question. If you were to ask "What is less dense than snow or water?" That would be a correct question.
