lower mantle उदाहरण वाक्य
उदाहरण वाक्य
- The physical properties of silicate perovskites under lower mantle conditions, such as seismic velocity, are studied experimentally using laser-heated diamond anvil cells.
- Once the slabs build up, they will sink through to the lower mantle in what is known as a " slab avalanche ".
- Akimotoite is elastically anisotropic and has been suggested as a cause of seismic anisotropy in the lower transition zone and uppermost lower mantle.
- It is difficult to melt mafic metamorphic rocks except in the lower mantle, so it is rare to see migmatitic textures in such rocks.
- The subsequent displacement into the lower mantle is caused by slab pull forces, or the destabilization of the slab from warming and broadening due to thermal diffusion.
- The eclipse plumage ( non-breeding ) of the male has more olive on the head and velvet red is restricted to the lower mantle and wing coverts.
- In the same paper the authors admit, however, that relative to the lower mantle, there is a slight westward component in the motions of all the plates.
- Slabs that penetrate directly into the lower mantle result in slower slab rollback rates ( ~ 1 3 cm / yr ) such as the Mariana arc, Tonga arcs.
- Two superplumes of molten rock appear to be powering through the boundary between the Earth's upper and lower mantle, perhaps feeding volcanoes and affecting movement of the planet's crust.
- Those elements all partition selectively into melts, however, and so were concentrated in the protocrusts and their derivatives, wherein the radioisotopes increased shallow temperatures while producing non-convecting lower mantles.
