As the amount of water increases, the melting point of rock decreases. Richard dropped two identical rocks, one into a puddle, and the other into a swimming pool. After dropping both rocks, the rock dropped into the puddle had a higher melting point than the other rock or a lower melting point than the other rock?

Q: We can say that resistance and current in an electric circuit areinversely proportional, because as the one increases, the other decreases, and vice versa. As the telephone line fell down and the line's resistance went up, the current was greater or smaller?
A: smaller

Question: In erosion, the higher the elevation, the farther the stream is from where it will reach base level and the more cutting it has to do. A stream in a state with a lower average elevation will have to do more or less cutting to reach base level that in a state with a higher average elevation?
Answer: less
