The atmosphere is made up of 4 distinct layers: the troposphere, stratosphere, mesosphere, and thermosphere. Different types of clouds form in the different layers depending on the pressure in the atmosphere and the ambient temperature. The cloud types include nimbus, stratus, cumulus, and cirrus. Figure 1 shows the location of the barriers of the atmosphere when the temperature and pressure are at an ideal condition for cloud formation. It also shows the different types of clouds formed at the different levels. Note: Clouds are formed mostly of water crystals, but can also contain particles of rock and dust.Which of the following statements about the formation of cumulus clouds is supported by data presented in figure 1Cumulus clouds form typically in

Correct answer: A. Pressures between 8 and 12 psi and at an average temperature of 35 degree c

  • A. Pressures between 8 and 12 psi and at an average temperature of 35 degree c
  • B. Pressures between 12 and 16 psi and at an average temperature of 22 degree c
  • C. Pressure of 4 psi and at average temperatures between 12 and 22 degree c
  • D. Pressure of 18 psi and at average temperatures between 50 and 60 degree c

Explanation

To answer this question you need to look at the information on cumulus clouds in Figure 1. Figure 1 suggests that cumulus clouds form in the mesosphere. The mesosphere's pressure ranges from 8 psi to 12 psi, and the average temperature for this range is 35◦ C. This information supports answer choice A.
