There are three main types of plate boundary: divergent, convergent and transform. Plates move away from one another at divergent boundaries. This happens at mid-ocean ridges. Plates move towards one another at convergent boundaries; one plate is forced below another in a process called subduction.
The skin of a Concord grape is typically dark blue or purple, and often is covered with a lighter-coloured epicuticular wax bloom that can be rubbed off. It is a slip-skin variety, meaning that the skin is easily separated from the fruit. Concord grapes have large seeds and are highly aromatic.
The American PACE Flag (Variant #1) uses the same color pattern as American PEACE Variant #1 (dark blue, cyan, very light blue, green, yellow, orange, red), but has the white word PACE inscribed over very light blue and green instead.
