The Many Meanders of the Jurua
November 14 | NASA Earth Observatory

Heavy sediment loads play a role in making the Jurua River one of the most sinuous rivers in the Amazon Basin. The Jurua emerges from highlands in east-central Peru, then winds its way through lowlands in Brazil. By the time it empties into the Amazon River near Fonte Boa, the river course spans more than 3000 kilometers (2,000 miles). But as the crow flies, the distance between the river*s source and mouth is only about 1000 kilometers (600 miles). Images from NASA*s Earth Observatory.

What is Frac Sand?
November 13 | Geology.com

Frac Sand: Close-up view of frac sand (on the right) and a typical sand of similar grain size (on the left). Notice how the frac sand has a more uniform grain size, nicely rounded grain shapes, and a uniform composition. It is also a very tough material that can resist compressive forces of up to several tons per square inch. Grains in this image are about 0.50 millimeter in size.

Mudstone: This photograph, taken by NASA*s Mars Rover Curiosity in 2015, shows sedimentary rocks of the Kimberley Formation in Gale Crater. The crater contains thick deposits of finely laminated mudstone that represent fine-grained sediments deposited in a standing body of water that persisted for a long period of time - long enough to allow sediments to accumulate to significant thickness.

Crater Lake Caldera: A satellite view of Crater Lake, one of the world's most famous calderas. Crater Lake formed about 7700 years ago when a massive volcanic eruption of Mount Mazama emptied a large magma chamber below the mountain. The fractured rock above the magma chamber collapsed to produce a massive crater over six miles across.

Oleshky Sands
November 10 | NASA Earth Observatory

North of the Black Sea, the landscape of southern Ukraine is awash with eye-catching landforms that beg the question: what is that? About 65 kilometers (40 miles) northwest of the colorful Sivash lagoons, the land abruptly turns from forest to sand. This oval-shaped region, known as Oleshky Sands, is the largest expanse of sand in Ukraine and the second-largest in Europe.
