Lecture 9: The Ganges Delta – Earth’s Fertile Lands

In the last lecture, we talked about the many mountain ranges that exist on the massive Tibetan Plateau, formed by the collision of India with Asia. Up to 3 billion people get their water from rivers that start in these mountains. In this lecture, we’ll look at two of those rivers, following them to their end to focus on the Ganges River delta. The Ganges River that runs on the south side of the Himalayas and the Yarlung Zangbo and Brahmaputra rivers that run on the north side and around the edge of the Himalayas join together and flow into the Indian Ocean in the Bay of Bengal. This is the site of the world’s largest delta.

Lecture 10: The Amazon Basin – Lungs of the Planet

Of all the objects in the solar system, Earth is the only one that has liquid water at the surface. Most of our planet’s water – perhaps the equivalent of 5 to 10 oceans – is actually located within the rock of Earth’s mantle. Most of the liquid water at Earth’s surface – 97 percent – is Antarctica and Greenland. A large portion of the remainder is in the Amazon River Basin, the most remarkable river system in the world.
