Question 1:C

Question 2:B

1 Question: This question examines the heating process of the atmosphere and the insulation effect of the atmosphere. Atmospheric absorption of solar radiation: selectivity (ozone and oxygen atoms in the atmosphere mainly absorb ultraviolet rays; Water vapor and carbon dioxide mainly absorb infrared rays), and rarely absorb visible light with the strongest energy in solar radiation, which is not the main direct heat source of the atmosphere. Ground radiation: Long-wave radiation, except a small part of which returns to space through the atmosphere, is mostly absorbed by water vapor and carbon dioxide in the atmosphere. Therefore, the ground is the main direct heat source of the lower atmosphere. Atmospheric inverse radiation: When the atmosphere warms up, it also emits infrared radiation, which is also long-wave radiation. Most of it radiates to the ground, which is called atmospheric inverse radiation, which supplements the loss of ground heat and plays the role of heat preservation. The picture shows the weather system transiting, with rainy weather, increased cloud cover and enhanced atmospheric reverse radiation. So this question chooses option C.

Question 2: This question examines frontal cyclones. The front near the ground is often combined with cyclone, which is called frontal cyclone. The left side of the cyclone is a cold front system, and the right side is a warm front system. The picture shows the cold front, which is easy to combine with the cyclone system. B in the picture is a cyclone. So this question chooses option B.
