Name the ocean that is the smallest and shallowest.

The Arctic Ocean is the smallest and shallowest of the world's oceans. Covering an area of about 15 million square kilometers, it is significantly smaller than the other major oceans and is surrounded by landmasses such as North America, Europe, and Asia. Its average depth is also less than that of the other oceans, making it unique in both size and depth.

Geographically, the Arctic Ocean is characterized by its polar climate, with sea ice covering much of its surface for at least part of the year. This ice plays a critical role in influencing global climate patterns and marine ecosystems. The shallowness of the Arctic Ocean contributes to its distinct environmental conditions, including less diverse marine life compared to the deeper, more expansive oceans.

The other oceans, such as the Atlantic, Indian, and Pacific, are all larger and generally deeper, which allows for more complex marine environments and ecosystems. Thus, the recognition of the Arctic Ocean as the smallest and shallowest is supported by both its physical dimensions and its ecological characteristics.
