Answer: Option D. -> Pressure only due to vapour in the air
Answer: (d)
Answer: (d)
Answer: Option A. -> Selective scattering of radiation by atmosphere
Answer: (a)The Sky appears blue due to scattering of light. Out of seven colors the lower wavelength blue light scattered more and it is reason behind the appearance of sky as blue.

Answer: Option A. -> hot and humid climate
Answer: (a)
The temperature of the equatorial regions is hot throughout the year, with a very low-temperature range usually of less than 3 degrees celsius. Tropical rainforest climate is a type of tropical climate in which there is little or no dry season – all months have mean precipitation values of at least 60 mm.
Tropical rainforest climates have no pronounced summer or winter; it is typically hot and wet throughout the year and rainfall is both heavy and frequent.
One day in an equatorial climate can be very similar to the next, while the change in temperature between day and night may be larger than the average change in temperature between “summer” and “winter”.

Answer: Option D. -> Condensation
Answer: (d)
Answer: (d)
Answer: Option D. -> is warmed by terrestrial radiation
Answer: (d)The air close to the ground is warmer because the earth's surface is what heats the atmosphere, for the most part. Terrestrial radiation accounts for much of the warming of air near the Earth’s surface. The further away from the earth's surface we go, the cooler the atmosphere.

Answer: Option A. -> Ozone
Answer: (a)The ozone layer of Earth’s stratosphere absorbs most of the Sun’s ultraviolet radiation. It absorbs 97 to 99 percent of the Sun’s medium-frequency ultraviolet light (from about 200 nm to 315 nm wavelength), which otherwise would potentially damage exposed life forms on the earth.
