Estuaries near the coast of Guinea?Bissau branch out like a network of roots from a plant. With their long tendrils, the rivers meander through the country?s lowland plains to join the Atlantic Ocean. On the way, they carry water, nutrients, but also sediments out from the land. This natural?color image captures the movement of the sediments as the rivers move east to west. The image was acquired on May 17, 2018, by the Operational Land Imager (OLI) on Landsat 8. The discoloration is most apparent in Rio Geba, which runs past the country?s capital city of Bissau. https://science.nasa.gov/earth/earth-observatory/the-meandering-estuaries-of-guineabissau-92266/

Young woman, wearing a orange jacket, is reading a book on an ebook reader during sunset over Himalayas. She is sitting on the top of a mountain and holding the e-reader.The afternoon sun on the background. Mount Everest National Park. This is the highest national park in the world, with the entire park located above 3,000 m ( 9,700 ft). This park includes three peaks higher than 8,000 m, including Mt Everest. Therefore, most of the park area is very rugged and steep, with its terrain cut by deep rivers and glaciers. Unlike other parks in the plain areas, this park can be divided into four climate zones because of the rising altitude. The climatic zones include a forested lower zone, a zone of alpine scrub, the upper alpine zone which includes upper limit of vegetation growth, and the Arctic zone where no plants can grow.
