2) What have meteorologists concluded about cloud seeding? a. It always causes a significant increase in precipitation. b.It never produces precipitation. c. It sometimes increases and sometimes decreases precipitation d.It has no effect on precipitation.

## Step 1<br />The problem is asking us to identify the correct conclusion that meteorologists have reached about cloud seeding. Cloud seeding is a form of weather modification that involves the dispersion of substances into the air to stimulate the formation of clouds and precipitation.<br /><br />## Step 2<br />The options provided are:<br />a. It always causes a significant increase in precipitation.<br />b. It never produces precipitation.<br />c. It sometimes increases and sometimes decreases precipitation.<br />d. It has no effect on precipitation.<br /><br />## Step 3<br />The correct answer is option c, which states that cloud seeding sometimes increases and sometimes decreases precipitation. This is because the effectiveness of cloud seeding can vary depending on a variety of factors, including the type of substance used, the altitude at which it is dispersed, the type of cloud, and the atmospheric conditions.
