In the northern hemisphere, south-facing slopes are warmest because the sun stays mostly in the southern half of the sky.

Introduction:
In the northern hemisphere, the direction a slope faces can greatly impact its temperature. The warmest slope in the northern hemisphere is the south-facing slope.

Explanation:
There are several factors that contribute to the south-facing slope being the warmest in the northern hemisphere.

Sun Exposure:
- South-facing slopes receive the most direct sunlight throughout the day. As the sun rises in the east and sets in the west, the south-facing slope is exposed to sunlight for the longest duration.
- The sun's rays are most intense when they strike the surface at a perpendicular angle. Due to the tilt of the Earth's axis, the south-facing slope receives the most direct and intense sunlight, resulting in higher temperatures.

Heat Absorption and Radiation:
- South-facing slopes have a higher capacity to absorb and retain heat compared to other slopes.
- When sunlight strikes the surface of the slope, it is absorbed, and the energy is converted into heat. South-facing slopes have a greater surface area exposed to sunlight, allowing for more heat absorption.
- The absorbed heat is then radiated back into the atmosphere, warming the air above the slope and contributing to higher temperatures.

Microclimates:
- Due to the exposure to sunlight and heat absorption, south-facing slopes often develop microclimates that are conducive to warmer temperatures.
- The warm air on the south-facing slope tends to rise and create a thermal uplift, which can trap heat and create a relatively warmer environment.
- The microclimate on a south-facing slope may also be sheltered from prevailing winds, further contributing to the warmer temperatures.

Conclusion:
In summary, the south-facing slope is the warmest compared to other slopes in the northern hemisphere due to its exposure to direct sunlight, increased heat absorption, radiation, and the development of microclimates. These factors combined make the south-facing slope the ideal choice for those seeking warmer temperatures.

Direction: Read the case study given below and answer any three of the questions that follow.In mountainous areas, the decrease in temperature with increasing altitude leads to a corresponding change in natural vegetation. Mountain forests can be classified into two types, the northern mountain forests and the southern mountain forests. The Himalayan ranges show a succession of vegetation from the tropical to the tundra, which change in with the altitude. Deciduous forests are found in the foot hills of the Himalayas. It is succeeded by the wet temperate type of forests between an altitude of 1,000-2,000 m. In the higher hill ranges of north eastern India, hilly areas of West Bengal and Uttaranchal, evergreen broad leaf trees such as oak and chestnut are predominant. Between 1,500-1,750 m, pine forests are also well developed in this zone, with Chir Pine as a very useful commercial tree. Deodar, a highly valued endemic species grows mainly in the western part of the Himalayan range. Deodar is a durable wood mainly used in construction activity. Similarly, the chinar and the walnut, which sustain the famous Kashmir handicrafts, belong to this zone. Blue pine and spruce appear at altitudes of 2,225-3,048 m. At many places in this zone, temperate grasslands are also found. But in the higher reaches there is a transition to Alpine forests and pastures. Silver firs, junipers, pines, birchand rhododendrons, etc. occur between 3,000-4,000 m. However, these pastures are used extensively for transhumance by tribes like the Gujjars, the Bakarwals, the Bhotiyas and the Gaddis. The southern slopes of the Himalayas carry a thicker vegetation cover because of relatively higher precipitation than the drier north-facing slopes. At higher altitudes, mosses and lichens form part of the tundra vegetation. The southern mountain forests include the forests found in three distinct areas of Peninsular India viz; the Western Ghats, the Vindhyas and the Nilgiris. As they are closer to the tropics, and only 1,500 m above the sea level, vegetation is temperate in the higher regions, and subtropical on the lower regions of the Western Ghats, especially in Kerala, Tamil Nadu and Karnataka. The temperate forests are called Sholas in the Nilgiris, Anaimalai and Palani hills. Some of the other trees of this forest of economic. Significance includes magnolia, laurel, cinchona and wattle. Such forests are also found in the Satpura and the Maikal ranges.Q. Deodar, a highly valued endemic species grows mainly in which part of the Himalayan range?
