SOLAR SYSTEM

Detailed explanation-1: -Which combination of temperature and pressure is inferred to occur within Earth’s stiffer mantle? 3, 500 degrees C and 0.4 million atmospheres.

Detailed explanation-2: -The pressure in the Earth’s inner core is slightly higher than it is at the boundary between the outer and inner cores: It ranges from about 330 to 360 gigapascals (3, 300, 000 to 3, 600, 000 atm).

Detailed explanation-3: -The mantle At close to 3, 000 kilometers (1, 865 miles) thick, this is Earth’s thickest layer. It starts a mere 30 kilometers (18.6 miles) beneath the surface. Made mostly of iron, magnesium and silicon, it is dense, hot and semi-solid (think caramel candy).

Detailed explanation-4: -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-5: -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.
