Because dead fishies build up at sea level and make a dense structure made of sea platypus.
Closest to the surface of the earth at Sea level or any portion of land that lies below Sea level.
The atmosphere is densest at sea level, so as the density of air goes down, so does the atmospheric pressure. The atmosphere gets less and less dense as you rise higher above the sea level.
The layer of the atmosphere at sea level is known as the troposphere. This is where most weather phenomena occur and it extends from the Earth's surface up to an average height of about 8 to 15 kilometers.
The most dense layer of the atmosphere is the troposphere is the most dense layer because it is at the bottom of the atmosphere. The troposphere is where all our weather happens. It also has the highest air pressure. But more specifically, the earths atmosphere is most dense at the surface.
The atmosphere is most dense at sea level, where the concentration of air molecules is greatest due to the weight of the air above pressing down. As altitude increases, atmospheric pressure decreases, leading to a lower density of air. This density gradient is why we experience thinner air at higher elevations, such as in mountainous regions. The majority of the Earth's atmosphere is concentrated within the first few kilometers above the surface.
the atmosphere isn't more dense. if the atmosphere was on the ground, we would have no air. but the reason the air is thinner in the mountains like mt. Everest and Kilimanjaro is because its further away from the earth center and the gravity has less effect on the air. the closer to the earth center the stronger gravity, the denser air.
Due to evaporation of water from the surface of the sea! The most dense gases in the atmosphere are naturally at the bottom. Also, with so much air being directly above all the way up about 100 Km being pulled down onto the lower air, the atmosphere is denser.
The atmosphere is more dense at the ocean than at the top of a mountain. As altitude increases, atmospheric pressure and density decrease, meaning that the air is thinner at higher elevations. Therefore, at sea level, such as at the ocean's surface, the atmosphere is denser compared to the air found at the summit of a mountain.
At sea level
1 atmosphere is equivalent to approximately 10 meters above sea level.
The average pressure exerted by the atmosphere at sea level is about 101.3 kilopascals, or 14.7 pounds per square inch.
The ocean is most dense towards the bottom of the sea. As the water in the ocean gets colder it gets more dense.
