The atmosphere of the earth is a thin spherical shroud composed of a mixture of gases and retained by gravitational attraction. It extends to a great height, but conventional flight is possible only in its denser layers. In fact, about 99% of the total mass of the air is found below ...
1英语翻译1.the height of the atmosphere is about 30km.the radius of earth is 6400km.what percentage of earth's radius is the height of the atmosphere?2.how would the density of air at the bottom of a deep mine shaft compare to the density of the atmosphere at the surface of the gro...
Although the density of the atmosphere changes with altitude, the composition stays the same with altitude, with one exception. In the ozone layer, at about 20 km to 40 km above the surface, there is a greater concentration of ozone molecules than in other portions of the atmosphere. Layers ...
Earth - Planet, Atmosphere, Geology: The mean distance of Earth from the Sun is about 149,600,000 km (92,960,000 miles). The planet orbits the Sun in a path that is presently more nearly a circle (less eccentric) than are the orbits of all but two of the
Earth's atmosphere extends from the surface to a height of around 10,000 km [6,213 miles]. Most of the air mass is confined to the lower part of the atmosphere and the higher the thinner of the air. Are there different layers in Earth's atmosphere? Yes. Mainly based on the chang...

The troposphere is the layer of the atmosphere we live and breathe in. It extends from sea level to a height ranging from 4.3 miles (7 kilometers) above the poles to 12.4 miles (20 km) over the tropics. As the layer of atmosphere that contains the most heat and moisture, it's also...
