SOLAR SYSTEM

Detailed explanation-1: -The correct answer is Decreases. As we go up the layers of the atmosphere, the pressure falls rapidly. Air pressure always decreases with the increasing altitude. Temperature increases as you gain altitude in the stratosphere and the thermosphere.

Detailed explanation-2: -As the density of the gases in this layer decrease with height, the air becomes thinner. Therefore, the temperature in the troposphere also decreases with height in response. As one climbs higher, the temperature drops from an average around 62°F (17°C) to-60°F (-51°C) at the tropopause.

Detailed explanation-3: -Among the given options only A is true because troposphere is thinner at the poles. The height of the troposphere varies from place to place and from season to season. The height of the troposphere at the pole is about 8 Km while at the equator it is about 16 Km.

Detailed explanation-4: -Temperature decreases with altitude because the troposphere is warmed from below, through absorption and re-emission of incoming solar radiation by the Earth’s surface, rather than being warmed from above by incoming solar radiation.

Detailed explanation-5: -Temperature of the troposphere is the highest near the surface of the earth. The temperature, however, decreases with increase in height or altitude. This decrease in temperature gradient is at the average rate of 6.4°C per kilometre and hence statement 4 is correct.

Detailed explanation-6: -The troposphere is warmest at the bottom near Earth’s surface. The troposphere is coldest at its top, where it meets up with the layer above (the stratosphere) at a boundary region called the tropopause. Temperatures drop as you move upward through the troposphere.

Detailed explanation-7: -The troposphere contains 75% of the atmosphere’s total mass. In either space or time the troposphere is not constant. Weather occurs in the troposphere. The troposphere is 10 miles from the equator. The troposphere is 5-7 miles above the poles. Does not contain ozone. More items
