Responsive Wordpress themes will adapt to any screen size viewing them. Design elements (such as navigation, sidebars, the main content) get repositioned (and possibly resized appropriately) to avoid horizontal scrolling on smaller resolutions, such as those of phones and tablets. In addition, images will also be resized to match the new proportions of the design. Responsive design is the future of the web, so it’s a major plus for your WordPress theme to be properly viewable on any kind of device.
