Siachen glacier is a valley type of glacier. The body of ice moving downslope under the impact of gravity through the valley bordered by rock valley walls in the mountain is called mountain glacier or valley glacier.

Moraines are accumulations of dirt and rocks that have fallen onto the glacier surface or have been pushed along by the glacier as it moves. The dirt and rocks composing moraines can range in size from powdery silt to large rocks and boulders.

A mass of rocks and other sediments carried down and deposited by a glacier, typically as ridges at its edge or extremity is called a morain.

Different types of moraine:

• Terminal moraines are found at the terminus or the furthest (end) point reached by a glacier.
• Lateral moraines are found deposited along the sides of the glacier.
• Medial moraines are found at the junction between two glaciers.
• Ground moraines are disorganized piles of rocks of various shapes, sizes and of differing rock types.

Alpine glaciers, also known as mountain glaciers or cirque glaciers, form on the crests and slopes of mountains. An alpine glacier that fills a valley is sometimes called a valley glacier. Alpine glaciers begin high up in the mountains in bowl-shaped hollows called cirques. As the glacier grows, the ice slowly flows out of the cirque and into a valley. Several cirque glaciers can join together to form a single valley glacier.

Moraines are odd among the combination. As moraines are the ridge-like depositional feature of a glacier. On the other hand, beaches, lagoons, and bars are the landforms of coastal regions. 

Rivers flowing into the Arabian Sea, such as the Narmada and Tapti, originate in mountainous regions and flow through narrow, steep paths. This high velocity prevents the deposition of sediments required to form deltas.

South-West monsoon has two branches, 1. Arabian sea branch, 2. Bay of Bengal branch. The moisture ladden winds of the SW monsoon follow the path of low pressure zone so as to reach ITCZ which is at ganga plains due to northward march of Sun over the tropic of cancer. While flowing towards ITCZ the Arabian Sea branch gets obstructed by the Western ghats, this gives heavy orographic rainfall on Western coast. On the other hand the bay of Bengal branch flows parallel to eastern ghats, so there is less precipitation.

The climate of any particular place is influenced by a host of interacting factors. These include latitude, elevation, nearby water, ocean currents, topography, vegetation, and prevailing winds. The global climate system and any changes that occur within it also influence local climate.

As the distance from the sea increases, people experience extreme weather conditions, i.e., very hot during summers and very cold during winters. This condition is known as Continentality.
