Earth’s mantle‚ crust‚ asthenosphere‚ and lithosphere? The core is divided into three major compositional layers. The crust on Earth’s surface‚ the rocky mantle beneath the crust and the metallic core which is the center of the Earth. While distinct and separate parts of Earth‚ they are all interconnected. The metallic inner core is solid‚ surrounded by a liquid (molten) outer core. Most of the mantle is solid‚ except for a layer very close to the crust boundary: the asthenosphere. The asthenosphere

church‚ the age of the earth was 6‚000 years old. 2. James Hutton discovered that the earth was much older from the tilted rocks because he knew these rocks was once laid down horizontally on the sea floor and were buried under great depth to be crystalized. Then they were tilted on end by great earth forces and then eroded away. The rocks were then deposited on top. He understood it had to take millions of years for this process to happen. 3. Lord Kelvin calculated the earth to be around 20 million
