What air is more dense the air in a mine or the air on the earths surface?

it depends on which part of the earth- at the beach or in a valley it would be more dense but on a mountain it would be fairly thin

Which statement correctly describes the density of Earth's mantle compared to the density of Earths core?
The mantle is less dense than the core but more dense than the crust.
True or False On avereage clouds reflect more solar radiation back to space than the earths surface?
no
What is the theory that earths surface is divided into more than 12 slow moving plates?
That theory relates to Plate Tectonics.
Why are more craters present on the moons surface than on earths?
because the moon does not have a equater like the earth to protact it self ;)
What is the area of Asia in square miles?
Asia - 17,212,000 sq. miles about 30% of the earths surface First off, Wrong. Second off, Wrong again. Water covers 75% of earths surface so how is Asia 30% of earths surface Even still, If Asia was 17,212,000 square miles then the Earth must be the size of Pluto xD Correct answer - Asia is more than 3 billion square miles
What portion of the earths crust is more dense oceanic or contenintal?
Oceanic crust is more dense.
Would an ore at earths surface or an ore deep underground be more expensive to mine?
it depends mainly it depends what level you can mine usally the higher the level you need to mine then is how much there worth==the higher the level the more money
What causes earths dense core?
Because the gravity is pushing the core together more so its more dense.
How much more is Earths surface of gravity than the Moon's?
Earths surface of gravity is 4.6m/s2 more than moons.
Which portion of earths crust is more dense. oceanic or continental?
Oceanic
How did rock affect the formation of earths layers?
As the earth formed, the heavier, more dense elements sunk toward the center, while the lighter, less dense ones stayed near the surface. The result was layers of rocks of similar density.
Does Venus have an atmoshpere?
Yes, an incredibly dense one. Mainly of carbon dioxide it is about 90 time more dense than the Earths atmosphere.
When you are you closer to the Moon's surface or the earths core?
None, only the earths core is more closer, the moons surface is 37.000 Vertices from earth
Is there more land or water on earths surface?
Roughly 71% of Earth is covered by water and because that is well over half there is more water than land on Earths surface
How does the density of air in a deep mine compare with the air density at the earth's surface?
Air is compressible (i.e. when you squish it it gets denser). This means that the air at the top of the atmosphere is less dense than the air lower down in the atmosphere because the weight of the air above squishes the air below it. If you go up in a lift in a tall building, your ears 'pop' because the air at the top is less dense than the air was at the bottom. As you go down a mine there is more air above you than at the top of the mine shaft so the air gets progressively denser the deeper you go. At the bottom of the mine the air is, therefore, more dense than at the earth's surface.
what is Part of earths surface that rises 1000 feet or more?
A Mountain
How does volcanos change the earths surface?
volcanoes change the earths surface due to the lava set hard and drys which can make the surface bobbly and ruff also it makes the land more fertilekill people
