What are the key differences between toast and roast in terms of cooking methods and flavors?

The key difference between toast and roast is the cooking method and the resulting flavors. Toasting involves heating bread quickly to make it crispy and golden brown, while roasting involves cooking meat or vegetables slowly in an oven to enhance their flavors and textures. Toasting gives a crunchy texture and a slightly nutty flavor, while roasting develops rich, caramelized flavors and tenderizes the food.
