IAS 2011 — Geography Climatology

Consider the following statements : 1. Statement I : The amount of dust particles in the atmosphere is more in subtropical and temperate areas than in equatorial and polar regions. 2. Statement II : Subtropical and temperate areas have less dry winds. Which one of the following is correct in respect of the above statements?

Consider the following statements : 1. Statement I : In January, in the Northern Hemisphere, the isotherms bend equatorward while crossing the landmasses, and poleward while crossing the oceans. 2. Statement II : In January, the air over the oceans is warmer than that over the landmasses in the Northern Hemisphere. Which one of the following is correct in respect of the above statements?

Consider the following statements : 1. Without the atmosphere, temperature would be well below freezing point everywhere on the Earth's surface. 2. Heat absorbed and trapped by the atmosphere maintains our planet's average temperature. 3. Atmosphere's gases, like carbon dioxide, are particularly good at absorbing and trapping radiation. Which of the statements given above are correct?
