Q.76. The average slope of warm front is
(A) 1:100 to 1:200
(B) 1:50 to 1:100
(C) 1:20 to 1: 30
(D) 1:10 to 1:20
Answer: A
Explanation
Warm front- a front in which warm air replaces cooler air at the surface.
- Some of the characteristics of warm fronts include the following:
- The slope of a typical warm front is 1:200 (more gentle than cold fronts).
- Warm fronts tend to move slowly.
- Warm fronts are typically less violent than cold fronts.
- Although they can trigger thunderstorms, warm fronts are more likely to be associated with large regions of gentle ascent (strati form clouds and light to moderate continuous rain).
- Warm fronts are usually preceded by cirrus first (1000 km ahead), then altostratus or altocumulus (500 km ahead), then stratus and possibly fog.
- Behind the warm front, skies are relatively clear (but change gradually).
- Warm fronts are associated with a frontal inversion (warm air overrunning cooler air).

Answer: D
Explanation
Q.78. The slope of a cold front varies from
(A) 1:50 and 1: 100
(B) 1:100 and 1: 200
(C) 1:200 and 1: 400
(D) 1:400 and 1:600
Answer: A
Explanation
Cold front- a front in which cold air is replacing warm air at the surface.
Some of the characteristics of cold fronts include the following:
The slope of a typical cold front is 1:100 (vertical to horizontal).
Cold fronts tend to move faster than all other types of fronts.
Cold fronts tend to be associated with the most violent weather among all types of fronts.
Cold fronts tend to move the farthest while maintaining their intensity.
Cold fronts tend to be associated with cirrus well ahead of the front, strong thunderstorms along and ahead of the front, and a broad area of clouds immediately behind the front (although fast moving fronts may be mostly clear behind the front).
Cold fronts can be associated with squall lines (a line of strong thunderstorms parallel to and ahead of the front).

| B. Katabatic Wind | 2. A tiny, white, granular ice particle |
| C. Rime | 3. Mountain Breeze |
| D. Storm Track | 4. Valley Breeze |
Codes:
| A | B | C | D | |

| C. | 4 | 3 | 1 | 2 |
| D. | 4 | 3 | 2 | 1 |
Answer: D
Explanation
Anabatic Winds are upslope winds driven by warmer surface temperatures on a mountain slope than the surrounding air column. Katabatic winds are downslope winds created when the mountain surface is colder than the surrounding air and creates a down slope wind.

Explanation
Our sun is the main source of energy and heat. It provides solar energy or fuel for the process of weather and climate. The energy emitted by the sun is known as solar radiation. The incoming radiation to the earth is known as isolation and it reaches in the earth in form of short waves.
Q.94. Which one of the following regions does not receive much rainfall during the south-west monsoon?
(A) Eastern Himalayas
(B) Chotanagpur
(C) Maharashtra
(D) Tamil Nadu Coast
Answer: D
Explanation
Most parts of India get, rainfall from South-west Monsoons with the exception of Tamil Nadu. Tamil Nadu lies on the leeward side for the southwest monsoon winds and receives lesser rainfall. Once the monsoon starts retreating after mid- September, North east monsoon sets in during mid-October, Tamil Nadu lies on the windward side for these winds and hence gets more rainfall during the winter season.

Answer: D
Explanation
Terrestrial radiation is the energy released by the Earth itself as opposed to solar radiation that it receives from the Sun.
Apart from the energy generated by the decay of radioactive minerals in rock, the energy that drives terrestrial radiation ultimately comes from the Sun, and it is a major factor in the study of global warming
