Question

Please select the word from the list that best fits the definition The part of the mantle called the _____ is made of soft rock that bends like plastic.

Answer 1

Asthenosphere

Explanation:

The asthenosphere is the upper part of the Earth's mantle. Located between 80 and 200 km of depth, it is a very viscous region. Given the condition of temperature and pressure in the asthenosphere, rocks in this region are very ductile, brittle and they can be bend very easily. Seismic waves pass slower through the asthenosphere than other regions of the mantles, due to the presence of these soft rocks.

Answer 2

Answer: The part of the mantle called the Asthenosphere is made of soft rock that bends like plastic

Explanation:

Layer lies just below the layer of lithosphere (rigid layer made by the crust and uppermost layer of the mantle). This include less rigid rocks than above which bends like plastic.

This soft layer is known as Asthenosphere.
