A valley is a low area between hills or mountains.

A V-shaped valley are formed by erosion from a river or stream over time. It is called a V-shaped valley as the shape of the valley is the same as the letter “V”.

U-shaped valleys are formed by the process of glaciation. They are characteristic of mountain glaciation in particular. They have a characteristic U shape, with steep, straight sides and a flat or rounded bottom.

Lauterbrunnen Valley, deep in the Swiss Alps, is stunning. It is so beautiful and fascinating so much so that, during a hike here in his youth, author J.R.R. Tolkien found inspiration for his Elven kingdom – Rivendell – in The Lord of the Rings. The valley was formed by three receding glaciers and has wooden, alpine chalet inns and 72 waterfalls cascading over the vertical limestone cliff faces. Not to mention the views of snow-capped mountains, being surrounded by the Eiger, Monch and Jungfrau peaks.

Spanning from Jordan in the Middle East way down to Mozambique in southern Africa, the Great Rift Valley is a colossal geological wonder. It’s a series of connected rift valleys created by the movement of tectonic plates that dates back 30 million years and is 6,000 kilometres (3,700 miles) long. Its volcanism has also produced Mount Kilimanjaro, Mount Kenya, hot springs and deep lakes but most importantly, is gradually splitting the horn of Africa from the continent.

The world deepest vally is the Yarlung Zangbo valley in Tibet. It has an average depth of 5,000 meters (16,400 feet), but explorers in 1994 discovered that its deepest point was 5,382 meters (17,657 feet). The peaks of Namche Barwa (7,753 m, 25,436 ft) and Jala Peri (7,282 m, 23,891 ft) are just 21 km (13 miles) apart with the Yarlung Zangbo River between them, at an elevation of 2,440 m (8,000 ft).
