Answer:
The force of friction is reduced between the blocks by adding the dishwashing liquid because the liquid is slippery and this makes it difficult for the two surfaces to contact each other directly. Therefore the blocks slip past each other rather than grinding against each other, producing less friction.

A higher temperature gradient causes faster heat transfer, and thus faster convection currents. If the core were cooler, the temperature gradient would be lower, so the convection currents would likely slow down.
Answer:
C. It is driven by natural processes like rock weathering and nitrogen fixation.
Explanation:
It has been discovered that eutrophication occurs through a gradual increase in the deposition of phosphorus and nitrogen and other plants nutrients in the water bodies.
This will allow the maximum growth of algae on the surface of the water.
It has been discovered that eutrophication is not good for the water bodies. This is because, the excess growth of algae on the surface of the water will prevent the sunlight from penetrating the water, thereby preventing the plants inside the water from making use of the sunlight to carryout photosynthesis. Also, it will prevent oxygen from entering, thereby depriving the organisms in the water from having the necessary oxygen needed for respiration.
