Rocks National Geographic
Rocks are so common that most of us take them for granted—cursing when we hit them with the garden hoe or taking advantage of them to drive in tent pegs on summer camping trips. But what exactly is a rock?
Times the Earth Tried to Swallow Us
Sinkholes—those terrifying natural phenomena known for gulping down unsuspecting houses, bridges, or even Corvettes—have been a hot topic in the news lately. Most of these newsworthy cave-ins are of the "cover-collapse" variety, in which soil beneath the surface begins to shift downward, leaving behind an increasingly large air pocket beneath a thin bridge of soil that manages to hold together until one day it doesn't, and suddenly: sinkhole.

50 Interesting Facts About The Earth
Alien worlds may be all the rage, with their mystique and promise, but the orb we call home, planet Earth, has all the makings for a jaw-dropping blockbuster movie: from the drama of explosive volcanoes, past meteor crashes and catastrophic collisions between rocky plates to the seeming fantasy of the ocean's deep abysses swirling with odd life and tales of the coldest, hottest, deepest, highest and all-out extreme spots.
Earth comes to life with stunning clips from the BBC's television archive. There is a lot to watch: See Mount St Helens erupt, the Earth form, and glaciers shrink.
Planet Earth National Geographic
arth, our home planet, is the only planet in our solar system known to harbor life. All of the things we need to survive are provided under a thin layer of atmosphere that separates us from the uninhabitable void of space. Earth is made up of complex, interactive systems that are often unpredictable. Air, water, land, and life—including humans—combine forces to create a constantly changing world that we are striving to understand.
Geologic Time Scale
Take a journey back through the history of the Earth — jump to a specific time period using the time scale below and examine ancient life, climates, and geography. You might wish to start in the Cenozoic Era (65.5 million years ago to the present) and work back through time, or start with Hadean time (4.6 to 4 billion years ago) and journey forward to the present day — it's your choice.
Death Valley's 'sailing stones'?
Professor Ralph Lorenz, a planetary scientist, believes the rocks become encased in ice during the winter, then as the lake bed thaws and becomes muddy, the ice allows the rock to 'float' on the mud - making them easily blown around by strong desert winds.
15 Most Amazing Landscapes ...
Shaped and sculpted over millions of years, these stunning landscapes and rock formations hold invaluable clues to Earth's past and future.
Grand Canyon National Park
Grand Canyon National Park, a World Heritage Site, encompasses 1,218,375 acres and lies on the Colorado Plateau in northwestern Arizona. The land is semi-arid and consists of raised plateaus and structural basins typical of the southwestern United States. Drainage systems have cut deeply through the rock, forming numerous steep-walled canyons. Forests are found at higher elevations while the lower elevations are comprised of a series of desert basins.
Located on Navajo land near Page, Arizona, Antelope Canyon is an incredible place where water and time have eroded the rock and turned it into a slot canyon. The result is an incredible formation of smooth, flowing rock. In 1997 the Navajo Tribe turned the area into a Navajo Tribal Park, opening up Antelope Canyon for tourism.

Spectacular Neon Blue Lava
You've heard of "red hot" and "white hot" to describe searing temperatures. But what about "blue hot"? That's the surreal hue of Indonesia's Kawah Ijen Volcano, which glows with an otherworldly "blue lava" at night.
