Which temperature zone of Earth's atmosphere contains the most water vapor? A) mesosphere B) stratosphere C) thermosphere D) troposphere 15. In which zone of the atmosphere would a temperature of 95ºC most likely occur? 16. Base your answer to the following question on the diagram below which shows part of the orbit of a satellite around the Earth.

3 24. Base your answer to the following question on the passage below. Ozone in Earth's Atmosphere Ozone is a special form of oxygen. Unlike the oxygen we breathe, which is composed of two atoms of oxygen, ozone is composed of three atoms of oxygen. A concentrated ozone layer between 10 and 30 miles above Earth's surface absorbs some of the harmful ultraviolet radiation coming from the Sun. The amount of ultraviolet light reaching Earth's surface is directly related to the angle of incoming solar radiation. The greater the Sun's angle of insolation, the greater the amount of ultraviolet light that reaches Earth's surface. If the ozone layer were completely destroyed, the ultraviolet light reaching Earth's surface would most likely increase human health problems, such as skin cancer and eye damage. State the name of the temperature zone of Earth's atmosphere where the concentrated layer of ozone gas exists. 25. As altitude within the troposphere increases, the amount of water vapor generally A) decreases, only B) increases, only C) remains the same D) decreases, then increases 26. Which list shows atmospheric layers in the correct order upward from the Earth's surface? A) thermosphere, mesosphere, stratosphere, troposphere B) troposphere, stratosphere, mesosphere, thermosphere C) stratosphere, mesosphere, troposphere, thermosphere D) thermosphere, troposphere, mesosphere, stratosphere
