Radical meaning vs characters in use
Yes you do, you just have to look further down the results of Google image search (and I wasn't expecting the top most images =.=). However, I don't think 阜 means dam, but it does mean mound, though in 99% cases it would be 土丘 or some other words because 阜 does not appear in conversational Chinese as far as I know. You get images related to ears because 阝 looks like an ear.
