identification of the use of the new
technology as a new experimental method

answer:

the new hypotheses proposed by different scientists are often criticized by the others because these new hypotheses contradict the ideas and hypotheses that already exist. adapting one's mind to a new hypotheses explaining a past event is often difficult when more clear hypotheses were already given earlier. thus, the hypotheses suggesting the extinction of the dinosaurs are difficult for the scientific community to accept.

explanation:

a rain shadow is a dry region of land on the side that is protected against the prevailing winds of a mountain range. the prevailing winds are the winds that occur most of the time in a particular place of the earth

prevailing winds carry air toward the mountain range. as the air rises up over a mountain range, the air cools, water vapor condenses, and clouds form. on this side of the mountains, called the windward side, precipitation falls in the form of  rain  or snow. this dry air produces a  rain shadow.
