The layer of Earth that is composed of silicate material is the mantle.
The correct answer is the mantle.
To determine which of Earth's layers is composed of silicate material, we can examine the composition of each layer.
1. Outer core: The outer core is primarily composed of liquid iron and nickel. It is responsible for generating Earth's magnetic field.
2. Crust: The Earth's crust is the outermost layer and constitutes the solid surface we live on. It is composed mainly of silicate rocks, such as granite and basalt.
3. Inner core: The inner core is a solid sphere composed mainly of iron and nickel. It is located beneath the outer core and is the Earth's innermost layer.
4. Mantle: The mantle lies between the crust and the core. It is the largest layer and makes up about 84% of the Earth's volume. The mantle is predominantly composed of silicate materials, including minerals such as olivine and pyroxene.
Based on this information, we can conclude that the layer of Earth composed of silicate material is the mantle.
