Layer of the atmosphere from 50 to 8o km above the earth's surface?
115476
The mesosphere (from the Greek words mesos = middle and sphaira = ball) is the layer of the Earth's atmosphere that is directly above the stratosphere and directly below the thermosphere. The mesosphere is located about 50-80/85km above Earth's surface. Within this layer, temperature decreases with increasing altitude. The main dynamical features in this region are the atmospheric tides which are driven by momentum propogating upwards from the lower atmosphere and extend into the lower thermosphere

That would be a cold (or at least cool), dry mass of air that originated over a large region of land near the north pole.  (Not over an ocean, unless it was the Arctic Ocean, which is covered by ice.)

Near outer space is at least 110 km above ground.

1st layer-The layer which is close to the earth's surface is called the troposphere.There are dense layers of gases in the troposphere.\n\n2nd layer-Above the troposphere is the stratosphere.The statosphere has higher clouds and jet aircrafts.There is a stretch of ozone gas in the lower part of the stratosphere.This is called the ozone layer.\n\n3rd layer -Above the stratosphere is the mesophere.\n\n4th layer-Above the meosphere is the ionosphere.The ionosphere  is useful for telecommunication.\n\n5th layer-Above the ionosphere is the thermosphere.Meteors burn up as shooting stars and auroras glow in the thermosphere\n\n6th layer-Above the thermosphere is the exosphere.Exosphere is the outer atmosphere.

the ozone layer keeps the earth a stable temperature.

Guess if you note the altitude of the sun at noon each day, mid summer will be the day it climbs highest in the sky, and mid winter would be when the sun is the lowest in the sky. Spring and fall are when the sun climbs to the lattitude you're at, and then you add or subtract 23.5 degrees (the tilt of the earth) to get the altitudes of the sun at summer and winter.\n\nSo if you know you're at lattitude 45 degrees, measure the altitude of the sun each day at noon, and you'll be in mid summer when the sun is at 68.5 degrees and in mid winter when the sun is at an altitude of 21.5 degrees.

I would think it would be the depths of the oceans up to about 5 miles into the atmosphere around the entire earth

are you asking for second layer from the bottom or form the top.\nFrom the bottom it is stratosphere, whichi houses the ozone layer. Many jet aircrafts fly in this layer because it is veru stable.\nFrom the top, it is the thermosphere. Auroras take place in this layer. It is also where the space shuttle orbits. It is also the layer in which space shuttles orbit.

It's only a gradual transition, but earth's atmosphere is pretty thin: at 15,000 feet half of the atmosphere is below you and it's noticeably harder to breathe and easier to get sunburned.

Atmospheric pressure is the pressure above any area in the Earth's atmosphere caused by the weight of air. Standard atmospheric pressure (atm) is discussed in the next section.\n\nAir masses are affected by the general atmospheric pressure within the mass, creating areas of high pressure (anti-cyclones) and low pressure (depressions).\n\nAs elevation increases, fewer air molecules are above. Therefore, atmospheric pressure decreases with increasing altitude. The following relationship is a first-order approximation:\n\n, \nwhere P is the pressure in pascals and h the height in metres. This shows that the pressure at an altitude of 31 km is about 10(5-2) Pa = 1000 Pa, or 1% of that at sea level1.

As you increase in altitude there is less atmosphere. Atmosphere includes the following gases... nitrogen, oxygen, water vapor, carbon dioxide, argon, methane, etc.\n\nNitrogen makes up the most of the atmospheric gases at roughly 78%. Since nitrogen is the majority of the gases, the light that reflects will be blue. Nitrogen absorbs all other colors except for blue so that is what we see.\n\nWhen you move up away from the earth, gravity has less of an effect on the gases. Most of the atmosphere is held closely to the earth. So as you go up, there is less air therefore less nitrogen. Less nitrogen means less scattering of blue light that you see.

Atmospheric pressure at sea level is caused by the weight of the atmosphere pushing downward. (weight /area).\n\nIf you approximate the Earth as a sphere, calculate the surface area of the sphere, and then multiply the pressure times the area you will get an approximation for the weight of the atmosphere.\n\nStandard pressure is 100 kPa. \nThe Earth's equatorial radius is roughly 6400 km\n\nSurface Area of a sphere is 4*pi*r^2 = pi*d^2\n\nMass = A*P
