Earth's outer core. Earth's outer core is a fluid layer about 2,260 km (1,400 mi) thick, composed of mostly iron and nickel that lies above Earth's solid inner core and below its mantle. [1][2][3] The outer core begins approximately 2,889 km (1,795 mi) beneath Earth's surface at the core-mantle boundary and ends 5,150 km (3,200 mi) beneath ...
Mathematics includes algebra. This can even have many levels, like the layers of an onion. The outer layers are sometimes called higher levels, giving a broader picture, and the inner lower levels, giving a more detailed view. But the important thing is, where the topic of one article includes another but the common name for both topics is the ...
The Mohorovičić discontinuity (/ ˌmoʊhəˈroʊvɪtʃɪtʃ / MOH-hə-ROH-vih-chitch; Croatian: [moxorôʋiːtʃitɕ]) [1] – usually called the Moho discontinuity, Moho boundary, or just Moho – is the boundary between the crust and the mantle of Earth. It is defined by the distinct change in velocity of seismic waves as they pass through ...
The internal structure of Earth are the layers of the Earth, excluding its atmosphere and hydrosphere. The structure consists of an outer silicate solid crust, a highly viscous asthenosphere, and solid mantle, a liquid outer core whose flow generates the Earth's magnetic field, and a solid inner core. Scientific understanding of the internal ...
Pedosphere – The outermost layer of the Earth that is composed of soil and subject to soil formation processes. Outer layers. By composition. Crust (geology) – The outermost solid shell of a rocky planet, dwarf planet, or natural satellite. Moho Discontinuity – The line between the crust and the Earth's mantle.
The geography of finance (or financial geography) is a branch of economic geography that focuses on issues of financial globalization and the geographic patterns of finance. It studies the effects of state sovereignty, culture, and different kinds of barriers that affect the spatial distribution of finance, such as uneven development and ...
Buying all your layers from one brand is a shortcut that can help ensure layers fit together well but only makes sense from a budget perspective if you are starting from scratch and don’t have ...
core–mantle boundary. outer core–inner core boundary. The core–mantle boundary (CMB) of Earth lies between the planet's silicate mantle and its liquid iron–nickel outer core, at a depth of 2,891 km (1,796 mi) below Earth's surface. The boundary is observed via the discontinuity in seismic wave velocities at that depth due to the ...
