Is the middle mantle the asthenosphere?
The asthenosphere is the semi-rigid part of the middle mantle that flows like hot asphalt under a heavy weight. The crust and the upper layer of the mantle together make up a zone of rigid, brittle rock called the Lithosphere.
What is the middle layer of the upper mantle called?
The lithosphere includes the brittle upper portion of the mantle and the crust, the outermost layers of Earth's structure. It is bounded by the atmosphere above and the asthenosphere (another part of the upper mantle) below.

What is center of Earth called?
Earth's core is the very hot, very dense center of our planet. The ball-shaped core lies beneath the cool, brittle crust and the mostly-solid mantle. The core is found about 2,900 kilometers (1,802 miles) below Earth's surface, and has a radius of about 3,485 kilometers (2,165 miles).

Why is the upper mantle called asthenosphere?
The upper mantle is called asthenosphere, “astheno” is a Greek word meaning 'weak'. It is called weak layer because it is in liquid state where rock material deforms more readily, and magma formation takes place.
What is the middle part of the Earth?
Finally, the center of Earth is called the core. It is an extremely dense area composed mainly of metals, where the temperature is above 6,000 degrees Celsius. Part of this heat, carried by the slow movement of molten matter, rises toward the surface and warms Earth's crust.
What is the middle layer of the atmosphere?
Both the stratosphere (next layer down) and the mesosphere are considered the middle atmosphere. The transition boundary which separates the mesosphere from the stratosphere is called the stratopause.
What is middle layer of Earth called?
The mantle is the mostly-solid bulk of Earth's interior. 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. 5 – 12+
What is the middle layer of the sun?
The Chromosphere The Chromosphere is the middle layer of the atmosphere of the sun. It measures 3000 to 5000 kilometres in depth. This layer of the sun's atmosphere has a rosy red colour and can be seen only during the eclipses.
Which place is Centre of world?
The place where French scientist Charles-Marie de La Condamine determined the (more or less) precise location of the Equator, is now marked by a large monument: La Mitad del Mundo, the centre of the world.
Where is the middle of the world?
The site, at latitude 0-0-0, near the village of San Antonio de Pichincha, is known as Mitad del Mundo — the Middle of the World.
Which country is heart of Earth?
In 1973, Andrew J. Woods, a physicist with Gulf Energy and Environmental Systems in San Diego, California, used a digital global map and calculated the coordinates on a mainframe system as 39°00′N 34°00′E, in modern-day Turkey, near the district of Kırşehir, Kırşehir Province, approx. 1,800 km north of Giza.
Is Ujjain center of Earth?
As per the Surya Siddhanta, a 4th-century astronomical treatise, Ujjain is geographically situated at the precise spot where the zero meridian of longitude and the Tropic of Cancer intersect. This is why it was considered the navel of the earth, and is called the “Greenwich of India”.
What 2 layers make up the mantle?
The mantle has two main parts, the upper mantle and the lower mantle. The upper mantle is attached to the layer above it called the crust. Together the crust and the upper mantle form a fixed shell called the lithosphere, which is broken into sections called tectonic plates.
What are the two mantles?
Two parts of the upper mantle are often recognized as distinct regions in Earth's interior: the lithosphere and the asthenosphere.
What is the lower mantle called?
The lower level of the mantle is called the asthenosphere and it is softer and weaker, particularly in its upper portion where a small amount of melting can occur.
Which is the middle layer?
The mantle lies just below the crust. It is semi-liquid and makes up 84% of Earth's volume. Earth's mantle is 2,900 km thick and is divided into 3 main zones, the lithosphere, asthenosphere, and mesosphere.
What is the name of middle layer of the sun?

What is in the exosphere?
The region above about 500 km is called the exosphere. It contains mainly oxygen and hydrogen atoms, but there are so few of them that they rarely collide – they follow "ballistic" trajectories under the influence of gravity, and some of them escape right out into space.
