Answer:The Earth's lithosphere is relatively hard rigid-like whereas, the asthenosphere is relatively hot and plastic-like
Explanation: The surface of the lithosphere has the rocks which can bent but does not flow , that is having rigid nature whereas the asthenosphere has comparatively have a flow in nature and are considered as plastic-natured .The lithosphere is segmented into rigid plates that are present on top of the flowing asthenosphere.
