SpletThe atmosphere is the layer of gases that surrounds the Earth. It is very important because it keeps us all alive! All living animals and plants on the planet need the atmosphere to survive. The atmosphere is held to the Earth by gravity. A mixture of gases make up the atmosphere, including: Known as the lower atmosphere, almost all weather occurs in this region. The troposphere begins at the Earth's surface, but the height of the troposphere varies. It is 11-12 miles (18-20 km) high at the equator, 5½ miles (9 km) at 50°N and 50°S, and just under four miles (6 km) high at the poles. As the density of … Prikaži več This is the outermost layer of the atmosphere. It extends from about 375 miles (600 km) to 6,200 miles (10,000 km) above the earth. In this layer, atoms and molecules escape … Prikaži več Between about 53 miles (85 km) and 375 miles (600 km) lies the thermosphere, known as the upper atmosphere. While still extremely thin, the gases of the thermosphere become increasingly denser as one descends … Prikaži več The stratosphere extends from from 4 -12 miles (6-20 km) above the Earth's surface to around 31 miles (50 km). This layer holds 19 percent of … Prikaži več This layer extends from around 31 miles (50 km) above the Earth's surface to 53 miles (85 km). The gases that comprise this layer continue to become denser as one descends. As such, temperatures increase as one … Prikaži več

SpletThe troposphere is the lowest layer of atmosphere of the Earth and the layers to which changes can greatly influence the floral and faunal environments. The troposphere extends from the surface of the Earth to a height of approximately 30,000 ft at the Polar Regions to approximately 56,000 ft at the equator, with some variation due to weather. Splet1.1.1. Mean Winds. Typically the winds in the boundary layer are backed and decreased from the geostrophic values through the retarding action of surface friction. Frictional retardation varies according to the differing surface features – quite high over rugged terrain or forests, moderate over open grassland or farmland, small over ... SpletThe boundary layer is the lowest part of the troposphere. A parcel of air moving upwards will cause the Atmosphere to be divided into four layers. This is based on factors such as temperature and density at that level, pressure, and difference in temperature. air higher is warmer than Air lower. michael rader knives
