layers according to temperature: troposphere‚ stratosphere‚ mesosphere‚ and thermosphere. The temperature drops as we go up through the troposphere‚ but it rises as we move through the next layer‚ the stratosphere. The farther away from earth‚ the thinner the atmosphere gets. 1.TROPOSPHERE This is the layer of the atmosphere closest to the Earth’s surface‚ extending up to about 10-15 km above the Earth’s surface. It contains 75% of the atmosphere’s mass. The troposphere is wider at the equator than

It contains 75% of the atmosphere’s mass. The troposphere is wider at the equator than at the poles. Temperature and pressure drops as you go higher up the troposphere. Q: Why is the troposphere wider at the equator than at the poles? The Tropopause: At the very top of the troposphere is the tropopause where the temperature

Each of the layers are bounded by "pauses" where the greatest changes in thermal characteristics‚ chemical composition‚ movement‚ and density occur. Troposphere The troposphere begins at the Earth’s surface and extends from 4 to 12 miles (6 to 20 km) high. This is the layer of the atmosphere in which we live. The height of the troposphere varies from the equator to the poles. At the equator it is around 11-12 miles (18-20 km) high‚ at 50°N and 50°S‚ 5½ miles and at the poles just under four

atmosphere listed from lowest altitude to highest altitude are the troposphere‚ stratosphere‚ mesosphere and thermosphere. The troposphere extends from the Earths surface up to about 14 kilometers in altitude. All human activities occur in the troposphere. The troposphere is the layer where all weather we experience takes place. It is a thin layer of the atmosphere. The warmest part of the troposphere is at the bottom. Commonly in the troposphere‚ altitude increases as temperature decreases. However there

temperatures may form compound molecules in their outer atmosphere. 2. The atmosphere is divided into five layers.* It is thickest near the surface andthins out with height until it eventually merges with space. The layers fromlowest to highest : - The Troposphere (up to 10 km) It’s the atmosphere thatsurrounds us. On top of that comes... - The Stratosphere; (10-50 km) Verylittle oxygen or water vapor. Aircraft fly in the lower stratosphere. This isalso where the ozone layer exists. On top of that comes.

What is the source of heat in the troposphere? Earth absorbs sunlight and then radiates it back as heat for the troposphere. 2. Describe the temperature gradient found in the troposphere. The temperature decreases with altitude. 3. Where and how do inversions form? Warm air is under cool
