What is the state of mantle for inner mantle?

The inner mantle, also known as the lower mantle, is a layer of Earth's mantle located beneath the upper mantle and above the outer core. It is primarily composed of solid silicate minerals, such as perovskite and magnesiowüstite, and remains solid due to the immense pressure it experiences. Although it is hot, with temperatures reaching up to 4,000 degrees Celsius (7,200 degrees Fahrenheit), the pressure prevents it from melting. The inner mantle plays a crucial role in the dynamics of plate tectonics and the geologic activity of the Earth.
