No, Earth does not have 7 layers.
Earth is structured into four main layers, according to current scientific understanding. These layers differ in composition and physical properties. Here's a breakdown of Earth's layers, based on the provided reference:
Earth's Four Layers
| Layer | Description | Temperature Range |
|---|---|---|
| Crust | The outermost solid layer. It is relatively thin and composed of various rocks and minerals. | Varies widely |
| Mantle | A semi-solid, rocky layer beneath the crust. It is the thickest layer of Earth. | Around 1000 °C to 3700°C |
| Outer Core | A liquid layer composed primarily of iron and nickel. This layer is responsible for Earth's magnetic field. | 4400 °C to 6100 °C |
| Inner Core | A solid, dense sphere composed mostly of iron and nickel, located at the very center of Earth. | 4400 °C to 6100 °C |
- The inner core is the deepest and hottest layer.
- The outer core is a liquid layer. The reference states that its temperature ranges from 4400 °C to 6100 °C (7,952 °F to 11,012 °F).
- The mantle is the thickest layer.
- The crust is the outermost and thinnest layer.
Therefore, based on current scientific consensus and the provided reference, Earth is made up of four, not seven, distinct layers.
