The Troposphere. The troposphere is the lowest layer of Earth's atmosphere. The troposphere starts at Earth's surface and goes up to a height of 7 to 20 km (4 to 12 miles, or 23,000 to 65,000 feet) above sea level.Most of the mass (about 75-80%) of the atmosphere is in the troposphere. Almost all weather occurs within this layer.ir pressure and the density of the air are also less at high altitudes. The layer above the troposphere is called the stratosphere. Nearly all of the water vapor and dust particles in the atmosphere are in the troposphere. That is why most clouds are found in this lowest layer, too.
