Question

Use the table to answer the question.
Day Observations
1 sunny and warm
2 cloudy and rainy
3 drop in temperature
4 clear skies and cold temperatures
A student tracks the daily weather. The student’s observations are logged in the
table. Which factor in the atmosphere best explains the student’s observations?
(1 point)
A cold front moved into the area.
A warm air mass replaced a cold air mass.
A warm front moved into the area.
High levels of moisture are contained within an air mass.

Answer 1

The best explanation for the student's observations is: **A cold front moved into the area.**

Here's the reasoning:
- The observation of "sunny and warm" on Day 1 suggests stable weather conditions.
- The "cloudy and rainy" on Day 2 indicates a disturbance in the weather pattern, commonly associated with the arrival of a cold front.
- A "drop in temperature" on Day 3 is typical following the passage of a cold front.
- Finally, "clear skies and cold temperatures" on Day 4 suggests that the cold front has passed, leading to clearer and colder conditions.

These observations align well with the effects of a cold front moving through the area.
