Solution:
Evening sun is not a shot as the mid-day sun because in the evening, radiations travel larger distance through atmosphere. Light from the sun, near the horizon, passes through thicker layers of air and covets a large distance in the earth's atmosphere before reaching our eyes. However, light from the sun overhead would travel realitively shorter distance.
32. Troposphere is the hottest part of the atmosphere because
Solution:
The troposphere is the layer of the atmosphere closest to the earth's surface where the weather takes place. The warmest temperatures in the troposphere are near the surface with the coldest temperatures being at the top of the troposphere.
33. Which one of the following layers of the atmosphere is responsible for the deflection of radio waves?
Solution:
High-speed and dangerous dry winds that periodically kick up and blow from the mountains to the coast in Southern California are referred to as Santa Ana winds.
35. Which one among the following is a high cloud?
Solution:
The most common form of high-level clouds are thin and often wispy cirrus clouds. Typically found at heights greater than 20,000 feet (6,000 meters), cirrus clouds are composed of ice crystals that originate from the freezing of supercooled water droplets.
