Answer:
Senators last 6 years in their positions, while Representatives only last 2 years. The reason for this difference is that the House of Representatives, for directly representing the people of the United States, is a more deliberative chamber and, as the interests of the people change constantly, it must be renewed to keep up with this issue.
Explanation:
Each state is represented by two senators, regardless of their population, who are elected by uninominal majority scrutiny. The Senate chamber is renewed by thirds every six years. In this way a senator lasts 6 years in office, being able to be re-eligible.
In turn, each state obtains in the House of Representatives a representation proportional to its population, with the right to a minimum of one representative; The most populous state, California, has 53 representatives. The total number of representatives is currently set at 435 by the Reapportionment Act of 1929, although Congress maintains the power to modify that number. Each representative is elected for a period of two years and can be re-elected.
