what is the earth's internal structure like?
14635
The internal structure of Earth is layered in spherical shells: an outer silicate solid crust, a highly viscous asthenosphere and mantle, a liquid outer core that is much less viscous than the mantle, and a solid inner core.

Earth has three layers: the crust, the mantle, and the core. The crust is made of solid rocks and minerals. Beneath the crust is the mantle, which is also mostly solid rocks and minerals, but punctuated by malleable areas of semi-solid magma.

1. Earth is also divided into layers based on physical properties, such as whether the layer is solid or liquid. 2. The five physical layers are the lithosphere, asthenosphere, mesosphere, outer core, and inner core.

You can think of the Earth as being made up of a number of layers, sort of like an onion. These layers get more and more dense the closer to the center of the earth you get. See the picture below to see the four main layers of the earth: the crust, mantle, outer core, and inner core.

The mantle lies between Earth's dense, super-heated core and its thin outer layer, the crust. The mantle is about 2,900 kilometers (1,802 miles) thick, and makes up a whopping 84% of Earth's total volume.

The Earth consists of three layers: the crust, the mantle and the core. The core, the innermost layer, is rich in iron and very dense. ... Most of the mantle is a thick fluid that moves in currents, but the very outermost portion of the outer mantle is solid. This portion and the solid crust make up the lithosphere.

Earth is a rotating sphere that orbits the Sun. The Earth's axis of rotation is at a constant tilt with respect to its orbit around the Sun, resulting in the change of seasons. The physical characteristics of the Earth include its size and composition. The Earth also has gravity and magnetic force fields.

Earth's interior is generally divided into three major layers: the crust, the mantle, and the core. The hard, brittle crust extends from Earth's surface to the so-called Mohorovicic discontinuity, nicknamed the Moho.

["Core. earth's center that consists of mostly iron.", 'Inner Core. made of solid iron.', 'Outer Core. made of molten iron.', 'Mantle. surrounds the core; thick layer of less dense, elastic rock.', 'Asthenosphere. upper mantle; contains soft rocks which are melted in some parts.', 'Lithosphere. ... ', 'Crust.']

The inner core is a hot, dense ball of (mostly) iron. It has a radius of about 1,220 kilometers (758 miles). Temperature in the inner core is about 5,200° Celsius (9,392° Fahrenheit). The pressure is nearly 3.6 million atmosphere (atm).

Seismic waves from large earthquakes pass throughout the Earth. These waves contain vital information about the internal structure of the Earth. As seismic waves pass through the Earth, they are refracted, or bent, like rays of light bend when they pass though a glass prism.

The innermost layers of the Earth. The Earth has an outer core (liquid) and an inner core (solid). They are not chemically distinct from each other, but they are chemically distinct from the mantle. The core is mainly composed of nickel and iron.

Earth is composed of multiple layers, which can be defined either by composition or by mechanical properties. The crust, mantle, and core are defined by differences in composition. The lithosphere, asthenosphere, mesosphere, and outer and inner cores are defined by differences in mechanical properties.

We live on the surface of Earth. Earth is a solid sphere consisting of: Core - The inner most part. Mantle - the region between the core and crust.

Earth's crust is a thin shell on the outside of Earth, accounting for less than 1% of Earth's volume. It is the top component of lithosphere: a division of Earth's layers that includes the crust and the upper part of the mantle.

Inside the Earth The Earth's interior is composed of four layers, three solid and one liquid—not magma but molten metal, nearly as hot as the surface of the sun. The deepest layer is a solid iron ball, about 1,500 miles (2,400 kilometers) in diameter.

​​The earth is made up of three different layers: the crust, the mantle and the core. This is the outside layer of the earth and is made of solid rock, mostly basalt and granite.
