but some experts are convinced that whatever created the SPA Basin did penetrate the Moon's mantle.And we need to find out, because much more than the crust, the mantle contains information about a planet's or moon's total composition.And that's key to understanding planet formation.um, Di...
What is the composition of the crust under the continents? Continental Drift: The continents as we know them are changing, but at a rate far too slow for humans to perceive as they are floating about on the Earth's mantle. This movement of the Earth's crust results in volcanoes, tsun...
The Nazca Plate is a tectonic plate to the west of the South American Plate. It is an oceanic plate, meaning its surface is below sea level, and this particular plate sits below the Pacific Ocean.Answer and Explanation: The composition of the Nazca Plate is similar to other oceanic ...
The composition of the mantle does not change that much from surface to core. In other words, the ratio of elements varies continuously throughout the mantle. However, the precise phase of the material does vary due to changes in pressure and temperature. These changes in phase, without a ...

An explosive fate awaits stars of less than about eight solar masses. Planetary nebulae are a type of supernova remnant formed when Sun-like stars first swell up to enormous sizes and then explode. When it happens to the Sun, its mantle will be flung outward to form a planetary nebula, ...
The Sao Miguel lavas define a remarkably linear array in Nd-Hf isotope space and point to an unusual composition below the mantle array. This a territory seldom occupied by sediments and the rarer terrigenous sediments that do have such isotopic compositions also have incompatible trace element ...
The composition of Earth's Moon is nearly the same as Earth's mantle. Furthermore, the Moon possesses a rather small iron core. Experts have pieced together the best possible scenario for its origin: Billions of years ago, a Mercury-sized object collided with Earth, which turned molten. ...
