B. DESCRIPTION

Lake Toba lies in the northern part of Barisan Mountain Range, which is volcanic and traverses Sumatra Island from northwest to southeast as its backbone.

The laketrough is surrounded by precipitous cliffs 400-1,200 m high. Based on the topographic feature and the wide distribution of volcanic ejecta around the lake, some geologists and valcanologists have considered it to be a giant caldera or cauldron.

The water surface of L. Toba is 905 m above sea level and about 1,100 km² wide. The total area of the lake, including the areas of Samosir and Paradapur Islands, amounts to 1,780 km². The mountains around the lake are called Batak Highlands. The only draining river from L. Toba, the Asahan, flows southeastwards dissecting the gentle slopes of the pyroclastic plateau.

TRAVEL

Travel is the movement of people between relatively distant geographical locations for any purpose and any duration, with or without any means of transport. Travel also includes relatively short stays between successive movements. Movements between locations requiring only a few minutes are not considered as travel. As an activity, "travel" also covers all the activities performed during a travel (movement).

Travel may be local, regional, national (domestic) or international. In some countries, non-local internal travel may require an internal passport, while international travel typically requires a passport and visa. Travel can be for recreational purposes, for tourism, to visit people, for business or for commuting, and may occur for numerous other reasons, such as to obtain health care, migration, fleeing war, etc. Travel may occur by human-powered transport such as walking or bicycling, or with vehicles, such as airplanes, private transport, public transport, automobiles and trains. from www. wikipedia.com
