Which Earth layer is located between the outer core and the crust
1. mantle
2. the mantle is both solid and liquid, while the inner core is entirely solid.
3. iron and nickel
4. the mantle’s mass is greater than the core’s mass, but with less density.
My bad I didn't include #5. 5. is It supports life in the ocean

The Earth layer located between the outer core and the crust is called the mantle. To understand this, let me explain how scientists have determined the composition and structure of the Earth.
Scientists have mainly relied on two sources of information to study the Earth's interior: seismic waves and direct samples from volcanoes and drilling. Seismic waves are vibrations that travel through the Earth, generated by earthquakes or human-made sources.
As these waves travel through the Earth, they experience changes in speed, direction, and amplitude, which give scientists clues about the different layers and their properties. By studying seismic waves, scientists have been able to determine the Earth's internal structure, including the mantle's location.
The mantle is the layer beneath the Earth's crust, extending downwards to the outer core. It is made up of solid rock, but it is denser and hotter compared to the crust. The mantle is further divided into two parts: the upper mantle and the lower mantle. The upper mantle is relatively rigid, while the lower mantle is more plastic-like in its behavior.
The mantle plays a crucial role in the movement of tectonic plates, which are large, rigid pieces of the Earth's crust that float on the semi-fluid upper mantle. This movement, known as plate tectonics, is responsible for earthquakes, volcanic activity, and the formation of mountain ranges.
In summary, the Earth layer located between the outer core and the crust is called the mantle, and it consists of the upper and lower mantle.
