Does a given volume of hot, humid air possess greater mass than an equivalent volume of hot, dry air? Surprisingly, the response is negative. When comparing equal volumes at the same temperature and elevation, humid… Which Is “Heavier”—Humid Air or Dry Air?
Within the atmosphere, there exists a continuous and dynamic movement of water, termed the hydrologic cycle. Given that the oceans encompass more than 70 percent of Earth’s surface, this cyclical process is best conceptualized as… Water Circulation in the Atmosphere
LATENT HEAT—THE HIDDEN WARMTH Water vapor exists as an invisible gas that only becomes perceptible when it undergoes transformation into larger liquid or solid (ice) particles. This alteration in physical form is recognized as a… What is meant by latent heat?
Vertical Structure of the Atmosphere Air molecules (as well as everything else) are held near Earth by gravity. This strong, invisible force pulling down on the air squeezes (compresses) air molecules closer together, which causes… CHAPTER:1 Earth and It’s Atmosphere Part 2
Overview of Earth’s Atmosphere The universe contains billions of galaxies and each galaxy is made up of billions of stars. Stars are hot glowing balls of gas that generate energy by converting hydrogen into helium… CHAPTER:1 Earth and It’s Atmosphere Part 1
Distribution of Wind and Pressure over the surface of the earth In subtropical region, the northeast trade winds and southeast trade winds prevail in the northern and southern hemisphere respectively. They are separated near the… Wind and Pressure Distribution on the Earth Surface for GSI, GG Gate, and CSIR Earth Science NET Exam
General Circulation of the atmosphere The simplest observed global characteristic of the atmosphere is that the tropics are much warmer than the poles. As discussed earlier, this is a straightforward consequence of the geometry of… Circulation of the Atmosphere for GSI, CSIR NET, and GATE GG Exam
Controls of Climate Climatic controls are the factors affecting the climate of a particular place. The most fundamental control of both weather and climate is the unequal heating and cooling of the atmosphere in different… Factors Controlling Climate: Overview of Climatic Controls for GSI, CSIR-NET, and GG GATE Exam Preparation
