There is no distinct boundary between the atmosphere and space, but an imaginary line about 68 miles (110 kilometers) from the surface, called the Karman line, is usually where scientists say atmosphere meets outer space. The troposphere is the layer closest to Earth's surface. It is 4 to 12 miles (7 to 20 km) thick and contains half of Earth's atmosphere. Air is warmer near the ground and gets colder higher up. Nearly all of the water vapor and dust in the atmosphere are in this layer and that is why clouds are found here. The stratosphere is the second layer.
Location. The stratosphere is situated between the troposphere and the mesosphere. The troposphere is the inner-most layer of the atmosphere that is closest to the Earth and produces weather.he stratosphere plays a large roll in the distribution of greenhouse gases and is therefore of tremendous interest to the scientific community. The stratosphere has characteristics that distinguish it from the other layers of the atmosphere.
