- Outer core
- Inner Core
- Seismic Waves
- Mechanical Waves
Solution
Identifying the Dense Sphere at Earth's Center
-
Understand the Options:
- Outer Core: A fluid layer composed of iron and nickel surrounding the inner core.
- Inner Core: A solid sphere made primarily of iron and nickel.
- Seismic Waves: These are waves of energy that travel through the Earth's layers during earthquakes.
- Mechanical Waves: These are waves that require a medium to travel through, which includes sound waves.
-
Determine the Composition:
- The inner core is known for being composed mainly of solid iron and nickel, and is under immense pressure and temperature.
-
Conclusion:
- The dense sphere of solid iron and nickel at the center of the Earth is referred to as the Inner Core.
