Most ovens are insulated metal boxes that contain two heating elements, one on the top of the oven and one on the oven floor. During preheating, both elements heat up, but when in baking mode, all the heat comes from the bottom..
Simply so, why is the top of the oven hotter than the bottom?
Ovens use air to transfer heat: you burn gas or heat an element at the bottom of the oven, and the hot air rises up into the oven, cooking your food. This makes this top of the oven much hotter than the bottom. In a typical oven, this difference can be very large.
Likewise, do ovens bake from the top or bottom? For baking, heat needs to come from the bottom of the cooking space, not the top, though many people swear by fan-assisted baking (aka a convection oven), which makes the heat come evenly from all sides, including top and bottom. You need to adjust baking times if you have a fan-assisted oven.

Preparation
- Position a rack in the center of the oven and heat the oven to 450°F.
- Put the chicken breast side up on a roasting rack in a medium (9×13-inch or similar) flameproof baking dish or roasting pan.
- Roast the chicken breast side down for 30 minutes.
Which rack is the middle of the oven?
The middle oven rack is the happy place where air is circulating, the heat sources are evenly distributed, and tops and bottoms aren't in danger of burning or browning too quickly. It's the perfect place for cakes, cookies, and brownies to stay and bake.
