What are the different kinds of presiding officers in the Senate, and what is the difference between them?

What will be an ideal response?

The constitutional president of the Senate is the vice president (VP) of the United States, but he rarely presides over the Senate, except in the case of ceremonial occasions or breaking a tie vote. The president pro tempore is the majority party senator with the longest continuous service and presides over the Senate in the absence of the VP. Finally, junior members of the majority party may preside in one-hour stints each day to help them become more familiar with Senate rules and procedures. Students should also mention the Senate majority leader since this person holds the most leadership authority.
