Role of Atmosphere in Earth Heat Balance

Sun is the major source of energy for the entire earth system. The earth does receive very small proportions of energy from other stars and from the interior of the earth itself (volcanoes and geysers provide certain amount of heat ..

Ionosphere Facts and role in Radio Transmission and Aurora

Ionosphere is called so because it is ionized by solar radiation. It plays an important part in atmospheric electricity and forms the inner edge of the magnetosphere. Ionosphere stretches from 50 to 1,000 km and typically overlaps both the exosphere ..

Measosphere Facts

The mesosphere extends from the stratopause to 80–85 km. Most meteoroids get burnt in this layer. Temperature decreases with height in the mesosphere. The mesopause, the temperature minimum that marks the top of the mesosphere, is the coldest place around ..

Facts About Stratosphere

The stratosphere is the second major layer of Earth’s atmosphere, just above the troposphere, and below the mesosphere. It is called stratosphere because it is stratified in temperature, with warmer layers higher up and cooler layers farther down. Top of ..

Facts About Troposphere and Tropopause

Troposphere is the lowest portion of Earth’s atmosphere and contains approximately 80% of the atmosphere’s mass and 99% of its water vapour and aerosols. The average depth of the troposphere is approximately 17 km in the middle latitudes. The characteristic ..

Atmosphere: Composition and Layers

Earth’s atmosphere is mainly consisted of nitrogen, oxygen, and argon, which together constitute the major gases of the atmosphere. The remaining gases are often referred to as trace gases. The below table shows the composition of Dry atmosphere. Composition of ..

How Tides are useful in Fishing?

Tides move water, bringing water in and taking water out. Understanding the cycles and effects of tides on fish helps in better fishing. The full and new moons normally create better fishing conditions because of the spring tides.  The reason ..

How Tides are useful in navigation?

Tidal flows as well as Tidal heights are of profound importance in navigation and very significant errors in position will occur if they are not taken into account. Many rivers and harbours have a shallow ” bar” at the entrance ..
