What is the name of the layer between the Earth's crust and the Earth's core?

The layer that lies between the Earth's crust and the Earth's core is called the mantle. The Earth's mantle is a thick layer of hot, solid rock that extends from the base of the crust to the top of the core. It accounts for approximately 84% of the Earth's volume and is composed mainly of silicate minerals rich in iron and magnesium.

The mantle can be further divided into two regions: the upper mantle and the lower mantle. The upper mantle is closer to the Earth's crust and consists of both solid and partially molten rock, known as magma. This region is responsible for the movement of tectonic plates, which leads to earthquakes, volcanic activity, and the formation of mountains. The lower mantle, on the other hand, is under immense pressure and is mostly solid due to the high temperatures and compression from the weight of the material above it.

The Earth's mantle plays a crucial role in the planet's geology and dynamics. It acts as a heat source, with the core's heat transferring to the mantle and then to the crust. This heat transfer drives convection currents within the mantle, causing the tectonic plates to move. These movements result in various geological phenomena, such as the creation of new crust at mid-ocean ridges, the subduction of one plate beneath another, and the formation of mountain ranges.

Understanding the structure and composition of the Earth's mantle is essential for studying the planet's history, evolution, and current processes. Scientists employ various methods, including seismic imaging and laboratory experiments, to gain insights into the mantle's properties and behavior.

In conclusion, the layer between the Earth's crust and the Earth's core is known as the mantle. This vast region of hot, solid rock plays a vital role in shaping the Earth's surface and influencing geological processes. Studying the mantle helps scientists unravel the mysteries of our planet's past and better predict its future.
