It causes erosion of the land and stones.

Explanation:

if the objects such as stones etc are present in the way of stream so the stones are eroded due to its fast flowing due to sloppy nature. If the stream is flat  then it little disturb the things present in its way because of its lower speed. If more rainfall occur the streams flows in higher speed and destroy everything that comes in its way and also affected the plains.

since the atomic number is the number of protons in the nucleus, as we move to the left on the periodic table, the electrostatic pull between the nucleus and the valence electron shell decreases. as we move down a group (vertical column), the valence shell energy level gets further and further from the nucleus.
