Q.1. Consider the following statements :
1. Dust particles are generally concentrated in the lower layers of the atmosphere; yet, convectional air currents may transport them to great heights.
2. The higher concentration of dust particles is found in subtropical and polar regions due to dry winds in comparison to equatorial and temperate regions.
3. Dust and salt particles act as hydrophobic nuclei around which water vapour condenses to produce clouds.

Q.3.With reference to the layers of the atmosphere, consider the following statements :
1. The thickness of the troposphere is greatest at the equator because heat is transported to great heights by strong convectional currents.
2. The air temperature at the tropopause is about -80°C over the poles and about -45°C over the equator.
3. In the mesosphere, temperature starts decreasing with the increase in altitude and reaches up to -100°C at a height of 80 km.
4. Radio waves transmitted from the Earth are reflected back to the Earth by the ionosphere.

2. Maximum insolation is received over the subtropical deserts, where the cloudiness is the least.
3. Equator receives comparatively more insolation than the tropics.
4. Generally, at the same latitude the insolation is more over the continent than over the oceans,
