A weather system is simulated by experiments: a partition is inserted in the middle of a plastic box, and equal volumes of red warm water (representing warm air) and blue cold salt water are injected into both sides respectively.

Question 1:D

Question 2:B

Question 3: A.

Question 1: This question examines the formation of the front. Red warm water has a low density, and above the interface, the interface between them is inclined. So choose option d in this question.

Question 2: Cold and warm air masses meet to form a frontal system. Therefore, the weather system simulated in this experiment is a frontal system. So this question chooses option B.

Question 3: The main disadvantage of this simulation experiment is that it can't simulate the change of air pressure, the weather phenomenon caused by clouds and the type of front. But obviously it can simulate the density difference between cold and warm air masses. So choose option a in this question.
