Multiple Answer 2 points Select all that are true about the mantle. makes up 84% of the earth's volume has the most magnesium mostly made of nickel and iron thinnest layer on earth mostly made of silicon and aluminum

The mantle is a layer of Earth located between the crust and the outer core. It is not the thinnest layer on Earth; that distinction belongs to the crust. The mantle is mostly made of silicon and aluminum, not nickel and iron. Nickel and iron are the primary components of the Earth's core. The mantle does make up a significant portion of the Earth's volume, but the exact percentage can vary depending on the source. However, it is generally accepted that the mantle makes up about 84% of the Earth's volume. The mantle also has the most magnesium among the layers of the Earth.
