Question

1. Fill in the blanks.
a) The
layer of mantle is in a molten state.​

Answer 1

Explanation:

The asthenosphere is the denser, weaker layer beneath the lithospheric mantle. It lies between about 100 kilometers (62 miles) and 410 kilometers (255 miles) beneath Earth's surface. The temperature and pressure of the asthenosphere are so high that rocks soften and partly melt, becoming semi-molten.

Answer 2

Answer:

The mantle has an average temperature of about 2200degree Celsius and the material is in a viscous semi molten state. The mantle act like fluid in response to slowly acting stresses and creeps under slow loads. But it behaves like as solid in presence of rapidly acting stresses, e.g. that caused by earthquake waves.
