SSAO is screen space ambient occlusion. It basically ads contact shadows where 2 objects meet. Just google ambient occlusion.

Tessellation is an effect to make 2D textures appear like 3D. Basically it's not 3D but the way the texture works tricks your brain into thinking it is 3D, it adds depths to surfaces where these textures are used.
