Witryna10 kwi 2024 · Even though Earth has been around 4.5 billion years, and geology is not a new field, our understanding of the planet’s innards is still immature, Hansen said. … WitrynaInside the sun. The structure of the sun is made up of four layers. At the very center is the dense, hot core. Around the core lie two layers: a thick layer called the radiative zone and a thinner, cooler layer called the convective zone. Surrounding all of them is the sun’s surface layer, known as the photosphere.
