Explanation:
1. noun. 1A deep basin excavated at the foot of a waterfall by the action of the falling water. 'It reminded Callan of a booming waterfall as it crashes into the plunge pool below. ... 'Spectacular waterfalls tumble into convenient plunge pools for the refreshment of weary walkers. '
A plunge pool is found at the bottom of a waterfall and is formed by erosion. As water drops over the waterfall then hits the ground beneath, it causes erosion, which forms a pool. This pool is known as a plunge pool.
2. The formation of a meander. As the river erodes laterally, to the right side then the left side, it forms large bends, and then horseshoe-like loops called meanders . The formation of meanders is due to both deposition and erosion and meanders gradually migrate downstream.
3. Humans use rivers for irrigation in agriculture, for drinking water, for transportation, to produce electricity through hydroelectric dams, and for leisure activities like swimming and boating.

Answer:
1. answer- A plunge pool is a deep depression in a stream bed at the base of a waterfall or shut-in. It is created by the erosional forces of cascading water on the rocks at formation's base where the water impacts. The term may refer to the water occupying the depression, or the depression itself.
2. answer- A meander is one of a series of regular sinuous curves, bends, loops, turns, or windings in the channel of a river, stream, or other watercourse. It is produced by a stream or river swinging from side to side as it flows across its floodplain or shifts its channel within a valley.
3. answer- Humans use rivers for irrigation in agriculture, for drinking water, for transportation, to produce electricity through hydroelectric dams, and for leisure activities like swimming and boating. Each of these uses can affect the health of a river and its surrounding ecosystems.
4. answer- The natural flow of water and fertile sediments from Indus river into the delta has been impeded due to the construction of dams along the river. The reduction of freshwater due to the dams also increases salinity, making the waters of the delta unsuitable for the freshwater species.
5. answer- The Indus River (called Sindhū in Sanskrit with cognates in most Indic languages)[1][2] is one of the main rivers of the Indo-Gangetic Plain in the Indian subcontinent.[3] It flows through China (western Tibet), India, and Pakistan.[4] Originating in the Tibetan Plateau in the vicinity of Lake Manasarovar, the river runs a course through the Ladakh region of India[a] towards Gilgit-Baltistan, and then flows in a southerly direction along the entire length of Pakistan to merge into the Arabian Sea near the port city of Karachi in Sindh.[5] The Indus is the longest river of Pakistan.[6]
6. answer- When a river reaches a lake or the sea the water slows down and loses the power to carry sediment. . The sediment is dropped at the mouth of the river. Some rivers drop so much sediment that waves and tides can't carry it all away. It builds up in layers forming a delta.
