State whether the following statements are true or false: Occuring of the full moon and new moon is a periodic change.

Answer

To determine whether the statement "The occurring of the full moon and new moon is a periodic change" is true or false, we can follow these steps:

### Step 1: Understand the concept of periodic change
- A periodic change is defined as a change that occurs at regular intervals of time. Examples include the changing of seasons, day and night, and the phases of the moon.

### Step 2: Analyze the moon phases
- The moon goes through a cycle of phases: new moon, first quarter, full moon, and third quarter. This cycle repeats approximately every 29.5 days.

### Step 3: Identify the regularity of the moon phases
- Since the new moon and full moon occur in a predictable and regular cycle, we can conclude that these events happen at regular intervals.

### Step 4: Formulate the conclusion
- Based on the analysis, we can state that the occurrence of the full moon and new moon is indeed a periodic change because it follows a consistent cycle.

### Final Answer
- Therefore, the statement "The occurring of the full moon and new moon is a periodic change" is **True**.
