A serac is an isolated block of ice that occurs on steep mountainous slopes. Seracs form when the glaciers that flow along these slopes break up rather than melt, creating huge surface fractures in the ice. Seracs are extremely dangerous, especially in summer when melt water from the glacier provides a lubricating layer between the ice and rock beneath leading to the threat of ice avalanches.


Sherpa literally means ‘people from the East’. The Sherpa people originated in eastern Tibet. Today, they are largely based in the Khumbu region of Nepal, to the south of Mount Everest. Sherpas have an outstanding worldwide reputation as mountain guides and porters. Their local knowledge of the Himalaya has been essential to the success of many international ascents of Everest. The first Sherpa to reach the summit of Everest was Tenzing Norgay in 1953.

Slave Trade:

The trade in African slaves began in ancient times. The trade reached its peak in the second half of the 18th century. A typical voyage for a British ship would involve a triangular course; south to the slave coast of West Africa to pick up cargo slaves who were transported across the Atlantic in terrible conditions to the West Indies or the North American colonies, from where sugar, cotton, tobacco would be shipped home.


Slavery describes the practice of capturing, selling and owning slaves. The trade existed between the 16th and 19th centuries. In the past slavery has been linked with the growth of empires.

Snow blindness:

Snow blindness is a painful condition caused by the over exposure of unprotected eyes to bright sunlight. Snow and ice have a high albedo, reflecting a very high percentage of sunlight. This glare causes much damage to the eyes. Those with snow blindness suffer initial pain when the eyes are exposed to bright light, followed by a temporary loss of vision. The condition disappears after a period of rest indoors. However, repeated high glare exposure can lead to permanent sight damage. It is often associated with mountaineering, especially in times before the creation of special snow goggles or dark glacier sunglasses. This is because mountaineers are often in environments with large amounts of snow and ice.
