Resampling means that you are changing the pixel dimensions of an image. When you lower the resolution, you are removing pixels and therefore removing information and detail from your image. When you increase the sample, you are adding pixels. Photoshop adds these pixels using interpolation.
Does resampling affect image quality?

Is resampling bad for Photoshop?
