Examples

• The barysphere makes up the majority of Earth's mass and volume.
• Geologists study the barysphere to understand the planet's internal structure.
• The barysphere is composed primarily of iron, nickel, and silicate rock.
• Temperature and pressure increase dramatically as you move deeper into the barysphere.
• The barysphere's composition differs significantly from the lighter lithosphere above it.
