Sure, I'll explain it for you.  I'm purposefully leaving out a ton of details and only giving you a high-level overview of things.

The Bitcoin network strives to add 1 block to the block chain every 10 minutes.  To accomplish this, it sets a target difficulty.  Every 2016 blocks that are added to the chain, the difficulty is recalculated.  If the average time to find those blocks is found to be under 10 minutes per block, the difficulty is increased.  If the average time is greater than 10 minutes, the difficulty is reduced.  If the average time is exactly 10 minutes, the difficulty remains the same.

In general, the more power that is added to the network, the faster the blocks are found, and the difficulty increases to compensate.
