Question

which chemical layer of earth makes up most of its volume? ○ crust○ mantle○ corethe inner core is solid. ○ true○ falsewhich layer has the highest density? *○ crust○ mantle○ core

Explanation:

1. Earth's mantle extends from just below the crust to the outer core, accounting for roughly 84% of the planet's total volume, more than the crust and core combined.
2. The inner core is a solid sphere composed mainly of iron and nickel, kept solid by the extreme pressure at Earth's center despite high temperatures.
3. The core, especially the inner core, is made of dense metallic elements (iron, nickel) and experiences immense pressure, making it the densest layer of Earth, far more dense than the mantle and crust.

Answer:

1. mantle
2. True
3. core
