SOLAR SYSTEM

Detailed explanation-1: -The temperature of the mantle varies greatly, from 1000°C (1832°F) near its boundary with the crust, to 3700°C (6692°F) near its boundary with the core. In the mantle, heat and pressure generally increase with depth.

Detailed explanation-2: -At the center of Earth is a solid iron inner core. The hot dense core has a radius of about 759 miles (1, 221 kilometers) and a pressure of about 3.6 million atmospheres (atm).

Detailed explanation-3: -In terms of its constituent elements, the mantle is made up of 44.8% oxygen, 21.5% silicon, and 22.8% magnesium. There’s also iron, aluminum, calcium, sodium, and potassium. These elements are all bound together in the form of silicate rocks, all of which take the form of oxides.

Detailed explanation-4: -What are the inferred pressure and interior temperature at the boundary between Earth’s outer core and inner core? 3.1 million atmospheres pressure and an interior temperature of 6300°C 1.
