1. Composition: The Earth's core is primarily composed of iron and nickel, with smaller amounts of other elements such as sulfur and oxygen.
2. Temperature: The temperature of the Earth's core is estimated to be around 5,700 degrees Celsius (10,300 degrees Fahrenheit), making it hotter than the surface of the sun.
3. Pressure: The pressure at the Earth's core is extremely high, reaching up to 360 gigapascals (GPa) or 3.6 million times the atmospheric pressure at sea level.
4. State: The Earth's core is believed to be in a solid state, with a solid inner core and a liquid outer core. The solid inner core is thought to be due to the immense pressure at the center of the Earth.
5. Magnetic field: The Earth's core is responsible for generating the planet's magnetic field, which protects the Earth from harmful solar radiation and helps guide migratory animals.
6. Size: The Earth's core is about 2,900 kilometers (1,800 miles) in radius, making up about 15% of the Earth's total volume.
7. Movement: The movement of molten iron in the outer core is thought to be responsible for generating the Earth's magnetic field through a process known as the geodynamo.

Characteristics of Earth's Core
1. Density:
- The core is the densest layer of the Earth, with an average density of approximately 13 grams per cubic centimeter.
- The outer core is less dense than the inner core.
2. Temperature:
- The core is the hottest layer of the Earth, with temperatures reaching up to 5,200 degrees Celsius (9,540 degrees Fahrenheit) in the inner core.
- The temperature decreases from the inner core to the outer core.
3. Composition:
- The core is primarily composed of iron and nickel, with some lighter elements such as sulfur and oxygen.
- The inner core is thought to be solid, while the outer core is liquid.
4. Structure:
- The core is divided into two layers:
- Inner core: A solid, spherical ball approximately 1,220 kilometers (760 miles) in radius.
- Outer core: A liquid layer surrounding the inner core, about 2,250 kilometers (1,400 miles) thick.
5. Pressure:
- The pressure at the center of the Earth's core is immense, estimated to be over 3.6 million atmospheres (53 million pounds per square inch).
6. Magnetic Field:
- The Earth's magnetic field is generated by the convection currents in the liquid outer core. This process is known as the geodynamo.
7. Rotation:
- The core rotates slightly faster than the rest of the Earth, completing one full rotation every 24 hours and 36 minutes.
8. Seismic Properties:
- The core is highly seismic, meaning that it can transmit seismic waves efficiently.
- The boundary between the core and mantle is known as the Gutenberg discontinuity, where seismic waves experience a sharp change in velocity.
