Sri Lanka is a country known for its diverse topography, comprising a mixture of flat lands, rolling hills, valleys, and mountains.
The elevation map of Sri Lanka reveals that the highest mountainous areas are located in the central region, while the surrounding low country is generally flat.
The hills and mountains act as a natural barrier to the monsoon winds coming from the Indian Ocean, resulting in a fluctuation of rainfall throughout the country.
Additionally, Sri Lanka is also known for its abundance of rivers and waterfalls, which add to the beauty of its topography.
The highest point in Sri Lanka is the Pidurutalagala Mountain, which stands at an elevation of 2,524 metres (8,281 feet).
The lowest point in Sri Lanka is the Indian Ocean, which has an elevation of 0 metres (0 feet).
Sri Lanka's topography can be similar to India and Nepal because of the presence of the Himalayas. However, unlike these countries, the highest mountains peaks in Sri Lanka are comparatively smaller and scattered.
