The short answer is no. The entire Earth rotates at a constant speed, completing one full rotation in approximately 24 hours. This means that every point on the Earth's surface, including the middle and outer parts, rotate at the same speed.
As mentioned before, the Earth's rotation speed is constant and approximately 1,037 miles per hour at the equator. This speed decreases as you move towards the poles, but it is still the same for both the middle and outer parts of the Earth.
No, the Earth's layers, including the outer crust, mantle, and core, all rotate at the same speed. This is due to the Earth's solid composition and its ability to transfer rotational energy throughout all of its layers.
If the middle of the Earth were to spin faster than the outer part, it would create significant disruptions and imbalances in the Earth's rotational motion. This would likely result in catastrophic geological events, such as earthquakes and volcanic eruptions.
Scientists use a variety of methods to measure the Earth's rotation speed, including satellite data, astronomical observations, and precise time measurements. These methods allow for accurate measurements of the Earth's rotation speed and any changes that may occur over time.
