SOLAR SYSTEM

Detailed explanation-1: -At the base of the mantle, about 2, 900 kilometers (1, 802 miles) below the surface, is the core-mantle boundary, or CMB. This point, called the Gutenberg discontinuity, marks the end of the mantle and the beginning of Earth’s liquid outer core.

Detailed explanation-2: -The core–mantle boundary of the Earth lies between the planet’s silicate mantle and its liquid iron-nickel outer core. Complete Answer: The boundary which lies between the mantle and the core is located at a depth of nearly 3000km.

Detailed explanation-3: -The earth’s outer core, on the other hand, is a liquid and is believed to be composed primarily of molten iron. This ocean of iron extends from about 2900 kilometers to 5200 kilometers beneath the earth’s surface to the inner core, which would lie from 2.9 to 5.2 cm beneath the surface of our softball sized world.

Detailed explanation-4: -Answer and Explanation: At a depth of 2, 000 kilometers the temperature of the stiffer mantle is about 2, 300 degrees Celsius (4, 200 Fahrenheit). The mantle is the part of the earth that sits between the crust and the core.
