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.
It is stated that the hard rocks don not flow while the flow can be seen in the plastic -like rocks.
So with the first number in each set, look on the x axis or the horizontal line for the number. For example, 2 1/2 on the horizontal line or x axis is on the right side, next to the two and the x. The second number is on the vertical side, and the same thing. In this case, -1 1/2 would be on the bottom in between the -1 and the arrow.
Now find the place where the two intersect on the coordinate plane, and put a dot there to mark the coordinate.
De = -2 , ef = -4 , df = -6
NON CONVENTIONAL =
Energy generated by using wind, tides, solar geothermal heat and biomass including farm and animal waste as well as human excreta is known as non-conventional energy. All these sources are renewable or inexhaustible and do not cause environment pollution. More over they do not require heavy expenditure.
