Mountains are prominent landforms that have significant heights above sea level and/or the surrounding land. They are steeper than hills. A mountain or mountain range usually has a peak, which is a pointed top. Mountains have different climates than land at sea level and nearby flat land.Mountains are very important for the ecosystem. They are a storehouse of water. Many rivers have their source in the glaciers in the mountains. With the help of these mountains, reservoirs are made, and the water is harnessed for the use of people.
