1) why do people want to learn about the past?


2) what is a period of 10years called?


3) how many days are in a calendar year?


4) what is a leap year?

People want to learn about the past because it helps us to not make the same mistakes our ancestors did, and, for some, it is interesting to know where they came from and their "story" if you will.

A period of 10 years is called a decade.

There are 365 days in a standard calendar year.

A leap year is a year that adds one extra day (February 29th) to make up for the lost time in the Earth. An Earth day is actually only 23 hours, 56 minutes, and 4 seconds, so the leap day makes up for that extra 3 minutes and 56 seconds.
