This is because most of the peaks in the Himalayas are situated above the snow line which is between 5000 to 5700 meters in the Himalaya. The climate snow line is the point above which snow and ice cover the ground throughout the year. The two types of plate boundaries that are most likely to produce volcanic activity are divergent plate boundaries and convergent plate boundaries. Mid-ocean ridges occur along divergent plate boundaries, where new ocean floor is created as the Earth's tectonic plates spread apart. As the plates separate, molten rock rises to the seafloor, producing enormous volcanic eruptions of basalt. The Greater Himalayas formed due to the collision of two continental plates that is the Indian plate and Eurasian plate. As we know that continental plates composed of granitic rocks that is why the Greater Himalayas are composed of granite
Himadri is the northernmost range of the Himalayan that is covered throughout the year as it's always covered with snow. It is the northernmost range of Himalayan which is also called the inner Himalayas which also include the most prominent peak of the Himalayan Mountain. The moisture for snowfall in this part of the range is delivered primarily by the summer monsoon. The mountains form a natural barrier that blocks monsoonal moisture from reaching the Tibetan Plateau to the north. This is because most of the peaks in the Himalayas are situated above the snow line which is between 5000 to 5700 meters in the Himalaya. The climate snow line is the point above which snow and ice cover the ground throughout the year. The Himalayas are mountains are cold due to higher altitude. Himadri is the northernmost range of the Himalayan that is covered throughout the year as it's always covered with snow. It is the northernmost range of Himalayan which is also called the inner Himalayas which also include the most prominent peak of the Himalayan Mountain. As air rises, the pressure decreases. It is this lower pressure at higher altitudes that causes the temperature to be colder on top of a mountain than at sea level. High altitudes have lower atmospheric pressure as compared to the plains. Low atmospheric pressure contributes to low temperature. Therefore, high altitude areas have low temperature when compared to the plains.
