The correct statement about the stratosphere is A. The atmosphere mainly moves horizontally, so it is called the stratosphere B. Temperature decreases with increasing altitude C. Should

A

Test question analysis: The temperature in the stratosphere rises with height. The reason is that ozone in the stratosphere is absorbed instead of oxygen atoms. Due to the ultraviolet rays in solar radiation, complex and changeable weather phenomena occur in the troposphere rather than the stratosphere. It is precisely because the temperature in the stratosphere is high at the top and low at the bottom, the air flow is stable, and convection is basically impossible, and it can only move mainly horizontally, so it is called the stratosphere.

Comments: This question mainly tests candidates’ understanding of the vertical stratification of the atmosphere. It requires candidates to be familiar with the temperature, density and atmospheric movement conditions of each layer of the atmosphere and their causes. The test questions are certain for candidates in the first year of high school. The difficulty level is moderately difficult.
