In theory, the root name servers should not have **that** many requests, as the name servers below it only need to query it once every 2 days for each top-level domain (including the country codes, ccTLDs) that an incoming request is for.
In practise, badly configured machines and networks are constantly sending requests for names that shouldn't leave private networks (such as .elvis, .tla, etc). Some companies even block incoming [UDP] packets, so they never receive the DNS reply, and so keep sending out bad requests. Recent studies suggest that over 90% of all root server queries are invalid.
