Why is Chrome taking so much memory and CPU?

Chrome browser uses one process for every tab by default. If you open the Windows Task Manager, you can see multiple Google Chrome processes. The idea behind this is should any one of your tabs crashes, it will not crash the entire browser, as each tab will have its process running. Only that tab will crash. This results in Chrome consuming high resources. The other cause could be your Plugins.
