INDIAN GEOGRAPHY

Detailed explanation-1: -Temperatures in the lower mantle the reach around 3, 000-3, 500 degrees Celsius and the barometer reads about 125 gigapascals, about one and a quarter million times atmospheric pressure.

Detailed explanation-2: -The fluctuating temperatures in the core depend on pressure, Earth’s rotation, and the varying composition of core elements. In general, temperatures range from about 4, 400° Celsius (7, 952° Fahrenheit) to about 6, 000° Celsius (10, 800° Fahrenheit).

Detailed explanation-3: -The mantle is 2, 990 km below the surface. The temperature is 1, 000-3, 000 degrees Celsius. The upper mantle is solid and the density is 3.5 g/3 cm. The mantle is 5-70 km below the surface.

Detailed explanation-4: -The temperature of the mantle varies greatly, from 1000° Celsius (1832° Fahrenheit) near its boundary with the crust, to 3700° Celsius (6692° Fahrenheit) near its boundary with the core. In the mantle, heat and pressure generally increase with depth. The geothermal gradient is a measurement of this increase.
