US Pennies! Just One or Two Questions About Them!?

The mass of pennies generally decreases with time, so…

1. Why is this? Why might the mass of pennies have decreased?

2. What might affect the mass of pennies besides when they were made?

3. What two elements are pennies made of?

If you could please list a source, that’d be great! The US Mint online is really prestigious, but I can’t find the right link. Any help?
