The beginning of the thermosphere starts around 50 miles above sea level. This layer of the atmosphere is where temperatures can reach thousands of degrees Fahrenheit due to the absorption of solar energy by gas molecules. It is also where the auroras occur.
1 atmosphere is equivalent to approximately 10 meters above sea level.
8,000 feet into the atmosphere
Air pressure is greatest at lower altitudes, such as at sea level, because there is more air above pushing down due to gravity. On top of a mountain, the air pressure is lower due to the reduced amount of air above. Similarly, above Earth's atmosphere, air pressure decreases significantly as altitude increases. Therefore, air pressure would be greatest at sea level, not on top of a mountain or above the atmosphere.
The exosphere begins around 600 km above sea level and extends upwards to about 10,000 km. At this height, the atmosphere is extremely thin, and it gradually transitions into outer space.
The boundary between the Earth's atmosphere and outer space is commonly defined by the Kármán line, which is located at an altitude of 100 kilometers (about 62 miles) above sea level. However, the atmosphere extends much further, with significant portions still present up to about 1,000 kilometers (620 miles) in altitude. Therefore, while the Kármán line serves as a reference point for the edge of space, the atmosphere itself continues to exist well above this level.
1 atmosphere is equivalent to approximately 10 meters above sea level.
8,000 feet into the atmosphere
The atmosphere becomes too thin to breathe at high elevations, typically above 8,000 feet (2,400 meters) above sea level.
The highest level of the atmosphere is the exosphere, which starts at about 500 kilometers above the Earth's surface and extends out to about 10,000 kilometers. This region is where the atmosphere gradually transitions into outer space and where satellites orbit the Earth.
Earth's atmosphere extends to about 10,000 km (6,200 miles) above sea level, but its density becomes increasingly thinner as altitude increases. The boundary between Earth's atmosphere and outer space is known as the Karman line, which is located at an altitude of 100 km (62 miles) above sea level.
Air pressure is greatest at lower altitudes, such as at sea level, because there is more air above pushing down due to gravity. On top of a mountain, the air pressure is lower due to the reduced amount of air above. Similarly, above Earth's atmosphere, air pressure decreases significantly as altitude increases. Therefore, air pressure would be greatest at sea level, not on top of a mountain or above the atmosphere.
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 thermosphere, located 50 to 300 miles above sea level, is the outermost layer of Earth's atmosphere. It transitions into the exosphere, which extends beyond the thermosphere and eventually fades into outer space.
35K Feet = 10.668 KM Atmosphere = 560 KM Airplane at 35,000 feet would be above approximately 1.9% of the earth's atmosphere.
The exosphere begins around 600 km above sea level and extends upwards to about 10,000 km. At this height, the atmosphere is extremely thin, and it gradually transitions into outer space.
The boundary of Earth's atmosphere is known as the "Kármán line," located about 100 kilometers (62 miles) above sea level. This is where the atmosphere becomes so thin that it is considered to transition into outer space.
Air pressure is the weight of the column of air above a specific point. As you move higher in the atmosphere, there is less air above you, so the weight pressing down decreases, causing lower air pressure. Therefore, air pressure decreases with an increase in altitude due to the reduction in the mass of air above that level.
