The large, majestic, flat-topped promontory known as El Yunque, Spanish for “the anvil,” rises high into the sky above the rivers and streams that run below, and has been a Puerto Rican icon since pre-Columbian times.
Oxford University scientists say that a global temperature rise of 2.7 degrees Fahrenheit could thaw the ground over a large area of Siberia, threatening the release of carbon from soil.
Researchers studying Arctic thermokarst failures in Alaska were alarmed to find climate-warming carbon dioxide gas may be releasing into the atmosphere at an unprecedented rate.
A study of the Umpqua River basin in the Oregon Coast Range helps explain natural processes behind the width of valleys and provides potentially useful details for river restoration efforts designed to improve habitats for coho salmon (Oncorhynchus kisutch).
Several lakes around the world are known for their salty content. Among the most well-known are the Great Salt Lake in Utah and the Dead Sea. But these bodies of water pale in comparison to Don Juan Pond in Antarctica, known as the saltiest body of water on Earth.

The different methods include landscaping methods to reduce evaporation, erosion, consolidation of topsoil, temperature, sandstorms and more, permaculture in general, planting trees, regeneration of salty, polluted, or degenerated soils, floodwater retention and...
Theodore Roosevelt National Park is located in western North Dakota in the United States. The park contains 70,446 acres of land that is separated into three distinct badland areas known as the Elkhorn Ranch Unit, the South Unit, and the North Unit.

A drainage divide, water divide, divide, or watershed is the line that separates neighboring drainage basins. In flat country the divide may be invisible (just a notional line on the ground either side of which water starts its journey to different waterways). While, in hilly country, the divide lies along peaks and ridges. Drainage divides are important geographical, and sometimes political boundaries. Roads and railways often follow divides to minimize slopes and marshes and rivers....
