The atmosphere extends about 600 kilometers (372 miles) above the Earth's surface, where it gradually thins out and merges with outer space. The boundary between Earth's atmosphere and space is known as the Karman line at an altitude of 100 kilometers (62 miles).
We think of the atmosphere as a big ocean of air around us, but the air around us is very thin relative to the size of the earth. The "thickness" of the atmosphere or the distance between the earth's surface and the "top" of the atmosphere is not exactly measurable. With increasing altitude the atmosphere fades slowly away into space. Therefore it is not easy to tell exactly how high the atmosphere really is. Perhaps 50 kilometers. (see answer "how far is it to outer space?")
Rockets generally pass through the Earth's atmosphere at an altitude of about 62 miles (100 kilometers) above the Earth's surface. This point is known as the Kármán line, which marks the boundary between Earth's atmosphere and outer space.
The layer of the atmosphere with the most gas molecules is the troposphere. This is the lowest layer, extending from the Earth's surface up to about 8 to 15 kilometers (5 to 9 miles) high, depending on geographical location. It contains approximately 75% of the atmosphere's mass and is where most weather phenomena occur, due to the high concentration of water vapor and other gases.
27.5 miles. It's above about 98% of the Earth's atmosphere.
230 miles out into space
The atmosphere extends about 600 kilometers (373 miles) above the Earth's surface.
The atmosphere extends about 62 miles (100 kilometers) above Earth's surface.
The moon is far beyond the earth's atmosphere. The boundary between the atmosphere and outer space is generally considered to be an altitude of 62 miles, although there is a noticeable effect on spacecraft as high as 75 miles. The average distance from the earth to the moon is 233,000 miles.
The end of the atmosphere is about 63 miles above the surface of earth
The atmosphere column extends about 621 miles (1,000 kilometers) above the Earth's surface. The atmosphere is divided into different layers based on temperature variations, with the troposphere being the layer closest to the Earth's surface and extending up to about 7 miles (11 kilometers) high.
High Atmosphere was created in 1965.
The stratosphere is one of many layers in the atmosphere on Earth. It begins at 10 kilometers (8 to14.5 miles) and ends at 50 kilometers high (about 30 miles).
The troposphere is the atmosphere zone closest to Earth's surface, extending from the surface up to about 11 miles (17 kilometers) high. It is where most weather phenomena occur and contains the majority of Earth's atmosphere.
The exosphere goes from about 400 miles (640 km) high to about 800 miles (1,280 km).
The atmosphere extends about 62 miles (100 kilometers) from the Earth's surface. This region is known as the exosphere and marks the outer limit of Earth's atmosphere.
