Earth’s mantle lies between the crust and the core and makes up the largest portion of the planet’s volume. It consists of hot, semi-molten rock that moves slowly over time. These movements drive tectonic plate activity and influence surface phenomena.
Key Characteristics
- Extremely high temperature and pressure
- Composed of silicate minerals rich in iron and magnesium
- Divided into upper mantle and lower mantle
Importance
- Drives plate tectonics
- Influences volcanic eruptions
- Contributes to Earth’s internal heat
Examples
- Magma rising during volcanic eruptions
- Movement of continents over millions of years
