उत्तर
- Mantle lies below the crust.
- The upper portion of the mantle is called as asthenosphere, The word “astheno” is a Greek word meaning 'weak'.
- It is in liquid state and it is from this weaker zone that the molten rock materials i.e., 'magma’ find their way to the surface during volcanic eruptions.
- Epicenters of deep seated earthquakes are also found here. Therefore, the upper mantle is called the 'asthenosphere’.
