Yet, our understanding of mantle convection remains enigmatic. Questions persist on a number of fundamental topics, ranging from the origin of large igneous provinces to whether the mantle is compositionally heterogeneous.Philip J. HeronEdward J. Garnero...
The lithosphere–asthenosphere boundary is usually referred to asthe LAB. The asthenosphere is almost solid, although some of its regions are molten (e.g., below mid-ocean ridges). The lower boundary of the asthenosphere within the mantle is not well defined. Is the mantle the thickest layer?

It is predominantly composed of ferro-magnesium silicates. The mantle isn't molten, but it nears melting point, once you get 100 to 200 kilometers below the planet's surface. The mantle contains convective material, which circulates heat and may be what causes movement in the tectonic plates...
In 2024, MySQL retains its mantle as the world’s most popular open source database. As a relational database system, MySQL stores data in rows and columns defined by schemas. MySQL derives part of its name from the SQL language, which is used for managing and querying data in databases....
Focusing on the hydrosphere, it encompasses all of Earth’s water, which is crucial for life. This sphere includes surface water, such as rivers, lakes, and oceans; groundwater that saturates the soil and rock beneath our feet; ice and snow found in polar regions and mountain peaks; and ...

Verizon as a carrier can become expensive very quickly, so an MVNO is a great way to get its speeds and coverage, without the blinding costs that usually come with it. The popular carrier Visible is also part of the Verizon family but not technically an MVNO (more on that below). Verizo...
Freshwater pearls are produced by placing a small piece of mantle tissue from another mollusc into the oyster. This tissue is then covered with a bead made from mother-of-pearl or glass. The oyster is returned to the water, allowing it to grow for several months to years. The oyster will...
