Going through the compilation of some facts about the Earth’s crust given below will help you get well-versed with this layer of the planet – the outermost layer of the Earth to be precise. Read on… Most of us know that the interior of the Earth is made up of four different layers...
Earth, third planet from the Sun and the fifth largest planet in the solar system in terms of size and mass. Its single most outstanding feature is that its near-surface environments are the only places in the universe known to harbor life. Learn more ab
Earthquake, any sudden shaking of the ground caused by the passage of seismic waves through Earth’s rocks. Earthquakes occur most often along geologic faults, narrow zones where rock masses move in relation to one another.

About 25 percent of the Earth's crust is silicon. Besides computer chips, silicon has many uses; weirder spots where this element appears include menstrual cups, breast implants and oven mitts — in the form of silicone. What makes silicon so special that is has an entire valley in ...
Following fracture lines marking weaknesses in the Earth’s crust, they dug out gorges and canyons that knifed deep into the jagged coast. To the east the land sloped more gently, and broader valleys were formed. During repeated periods of glaciation in the Great Ice Age of the Quaternary ...
Plate tectonics—the shifting of large, relatively thin segments of Earth’s crust—and stream erosion have done the most to create Arizona’s spectacular topography. Specifically, the Pacific Plate and the North American Plate came into contact and created the major tectonic forces that uplifted,...
Geologically, it is one of the oldest and most stable parts of the Earth’s crust. Its surface formations and soils were altered by the receding glaciers of the Pleistocene Epoch (about 2,600,000 to 11,700 years ago). Lakes dot the fairly flat landscape, and thousands of islands form ...
Moon, Earth’s sole natural satellite and nearest celestial body. Known since prehistoric times, it is the brightest object in the sky after the Sun. Its name in English, like that of Earth, is of Germanic and Old English derivation.
Pangea, supercontinent that incorporated almost all of Earth’s landmasses in early geologic time. Fully assembled by the Early Permian Epoch (some 299 million to about 273 million years ago), it began to break apart about 200 million years ago, eventual
