Overview

The Earth's Internal Furnace: Geothermal Gradient, Earth's Layers, Heat Generation by Radioactive Decay The Earth's Internal Furnace The Earth's internal furnace is the heat and energy that comes from the center of the Earth. This heat and energy makes life and the atmosphere possible on the Earth's surface. Geothermal Gradient The Earth's internal furnace plays an important role in maintaining the temperature on the Earth's surface. The heat from the Earth's internal furnace radiates out to the Earth's surface and helps to maintain the temperature on the Earth's surface. Earth's Layers The Earth can be divided into four layers: crust, mantle, and core. - Crust: The Earth's outermost layer. It makes up only 1% of the Earth's total diameter. The thickness of the crust ranges from 5 kilometers below the ocean to 70 kilometers at the equator. - Mantle: The Earth's second layer. It makes up 83% of the Earth's total diameter. The thickness of the mantle ranges from 2,900 kilometers to 5,200 kilometers. - Core: The Earth's innermost layer. It makes up only 16% of the Earth's total diameter. The thickness of the core ranges from 2,900 kilometers to 6,371 kilometers. Heat Generation by Radioactive Decay The Earth's internal furnace is powered by radioactive decay. Radioactive decay is a process in which unstable atoms break down and release heat. The heat from radioactive decay is what keeps the Earth's interior hot. This is a more concise and accurate translation of the Telugu title. It is also more consistent with the style and grammar of English scientific writing.
