Troposphere
The atmosphere is denser near the Earth's surface because gravity pulls the air molecules towards the ground, compressing them and increasing their density. As you move higher in the atmosphere, there are fewer air molecules above you, leading to lower pressure and density.
The troposphere is the lowest layer of Earth's atmosphere where the air is densest and contains the majority of Earth's weather. It is perfect for life on Earth because it contains the oxygen we need to breathe, shields us from harmful radiation from the sun, regulates the planet's temperature through the greenhouse effect, and provides the conditions necessary for precipitation, which supports plant and animal life.
If air was to retain the heat from the sun during saylight hours then the earth would stay warmer for longer, however air is constantly moving so we get air from different parts of the world. so if it is cold near to the UK while they have sunlight and we have night time then we are more likely to be cold so even if air was a better heat conductor we would not be warmer during the night.
Without air, Earth would not be able to sustain life as we know it. There would be no oxygen for humans and animals to breathe, no atmosphere to regulate temperature, and no air pressure to support liquids and maintain water cycle. The absence of air would result in a barren and uninhabitable planet.
gravity helps pull down the layers of the atmosphere and the upper atmosphere is further away so its going to have less of a pull on it there for being less dense then the closest atmosphere. hoped that helped.
No, the thermosphere is not the densest layer of Earth's atmosphere. In fact, it is one of the least dense layers, characterized by very thin air and high temperatures due to solar radiation. The densest layer of the atmosphere is the troposphere, where most of the Earth's weather occurs and where the air is thickest.
All matter is densest and heaviest at precisely absolute zero, which is -273.15 degrees Celsius.
At the bottom of a deep mine.
A rare-earth metal with the symbol Lu and atomic number 71. It is a silvery white metal that resists corrosion in dry air but not in moist air. It is the densest and the highest-melting rare-earth element and the last member of the lanthanide series.
There would be no life on Earth
Because it contains the gasses for no life. Lots of harmful gasses.that will KILL you.
without air we would not be here on earth.
Thre are no "layers" in the atmospher, it is a gradient from the surface on up. The lowest area, the troposhere, is the densest. However the bottoms of mine shafts would have even denser air and the most air molecules per unit volume.
we all would die
The atmosphere is denser near the Earth's surface because gravity pulls the air molecules towards the ground, compressing them and increasing their density. As you move higher in the atmosphere, there are fewer air molecules above you, leading to lower pressure and density.
If the Earth didn't have gravity, we would be floating in the air and nothing would be in its place.
if there is no air we would die and nothing would be on earth we would be history and your suppose to learn about this and grade 1-3 as science so you should know this by now
