Oh no! This page was snatched by this mandrill.
This endangered mandrill (Mandrillus sphinx) was photographed by National Geographic Photographer Joel Sartore on Bioko Island, Equatorial Guinea, in his ambitious project to document every species in captivity—inspiring people not just to care, but also to help protect these animals for future generations. Before drills disappear, like this webpage has, learn how …
Lithosphere - Education | National Geographic Society
2023年11月29日 · The lithosphere is the solid, outer part of Earth. The lithosphere includes the brittle upper portion of the mantle and the crust, the outermost layers of Earth’s structure. It is bounded by the atmosphere above and the asthenosphere (another part of …
The lithosphere is the solid, outer part of the Earth. The lithosphere includes the brittle upper portion of the mantle and the crust, the outermost layers of Earth’s structure. It is bounded by the atmosphere above and the asthenosphere (another part of the upper mantle) below. The lithosphere is the most rigid of Earth’s layers.
Lithosphere - Education | National Geographic Society
2023年11月29日 · The lithosphere is the solid, outer part of the Earth. It includes the brittle upper portion of the mantle and the crust , the planet's outermost layers. The lithosphere is located below the atmosphere and above the asthenosphere .
Mantle - Education | National Geographic Society
2024年4月30日 · Lithosphere. The lithosphere is the solid, outer part of Earth, extending to a depth of about 100 kilometers (62 miles). The lithosphere includes both the crust and the brittle upper portion of the mantle. The lithosphere is both the …
Seafloor Spreading - Education
2023年11月29日 · Seafloor spreading is a geologic process in which tectonic plates —large slabs of Earth's lithosphere —split apart from each other. Seafloor spreading and other tectonic activity processes are the result of mantle convection. Mantle convection is …
Earth's Shifting Tectonic Plates - Education
2023年10月19日 · Tectonic plates, the massive slabs of Earth’s lithosphere that help define our continents and ocean, are constantly on the move. Plate tectonics is driven by a variety of forces: dynamic movement in the mantle , dense oceanic crust interacting with the ductile asthenosphere , even the rotation of the planet.
Earth's Systems - Education
2023年10月19日 · The five systems of Earth (geosphere, biosphere, cryosphere, hydrosphere, and atmosphere) interact to produce the environments we are familiar with.
Hydrologic Cycle - National Geographic Society
2023年10月19日 · The water cycle describes how water is exchanged (cycled) through Earth's land, ocean, and atmosphere. Water always exists in all three phases, and in many forms—as lakes and rivers, glaciers and ice sheets, oceans and seas, underground aquifers, and vapor in the air and clouds. Evaporation, Condensation, and Precipitation. The water cycle consists of …
Plate Tectonics - Education
2024年3月7日 · In plate tectonics, Earth’s outermost layer, or lithosphere —made up of the crust and upper mantle—is broken into large rocky plates. These plates lie on top of a partially molten layer of rock called the asthenosphere.
