Fill in the blanks to complete the sentence. Not all answer choices will be used.

The air in Kansas City was
on October 25 and 26. On those days, the air contained 100% of the
it was capable of holding.

When relative humidity is 100%, the air is saturated with water vapor. This means it cannot hold any more moisture. When saturated air cools, water vapor condenses into a liquid. Liquid water falls back to Earth as precipitation, including rain, snow, sleet, and hail.

Review additional data from Kansas City in the graph below. Use the graph to identify conditions that make precipitation most likely to occur.A line graph of atmospheric pressure, a line graph of relative humidity, and a bar graph of precipitation are shown over 10 days. Atmospheric pressure is 29.1 inches of mercury on Day 18, decreases to 28.95 on Day 19, then steadily increases to 29.4 by Day 24. It steadily decreases to 29.1 on Day 26, and returns to 29.25 on Day 27. Maximum relative humidity is 80% on Day 18, increases to 95% on Day 19 and 20, returns to 80% on day 22 and 23, decreases to 67% on Day 24, increases to 100% on Day 25 and 26, and falls to 92% on Day 27. Precipitation occurs on Day 20, 21, and 26.

Answer 1

1. On October 18, the maximum relative humidity recorded that day was **B 80%**.

2. Fill in the blanks to complete the sentence:

The air in Kansas City was **saturated** on October 25 and 26. On those days, the air contained 100% of the **moisture** it was capable of holding.

3. For the weather conditions on October 24 and October 26 based on the graph (please note that I would need specific options from an answer bank to sort them accurately):

- **October 24**:
- Relative humidity was **67%**.
- Atmospheric pressure was decreasing.

- **October 26**:
- Relative humidity was **100%**.
- Atmospheric pressure was low.

4. According to the graph, the weather conditions in Kansas City when it rains are best described by:

**C Relative humidity is high and atmospheric pressure is low**.

5. Regarding whether knowing the relative humidity is enough to make an accurate prediction about rain:

**Observation**: While high relative humidity indicates a greater possibility of rain, it is not sufficient alone to predict rain. Other factors, such as changes in atmospheric pressure, temperature, and recent weather patterns, also play critical roles in whether precipitation will occur. Thus, a comprehensive assessment of multiple weather conditions is necessary for an accurate prediction.
