(1) True.
- The heat from the radioactive processes within the planet causes the plates to periodically move towards each other and periodically separate from each other. This movement is called plate movement or structural movement.
- Plate tectonics is a scientific hypothesis that characterizes the large-scale effects of the Earth's lithosphere. Although the tectonic plate consists of a marine lithosphere and a thicker continental lithosphere.
(2) True
- Himalayan mountains are stretched over the northern borders of India. These mountain ranges run in a west-east direction from the Indus to the Brahmaputra. The Himalaya consists of 3 parallel ranges in its longitudinal extent.
(3) True
- The Brahmaputra river marks the easternmost boundary of the Himalayas. This originates from Mansarovar Lake, which is also a source of the Indus and Sutlej. It is 3848kms long, a little longer than the Indus River.
(4) True
- Just like rugged terrains and uneven landforms are sparsely populated. Life-sustaining elements are more likely to attract population, which are provided by the Northern Plains.
(5) True
- Western ghats are higher in elevation than eastern ghats, making passage through them difficult
