Size and Depth Variations
Lakes, ponds, rivers, and oceans represent a wide spectrum of sizes. While some lakes are no larger than a football field, others span vast areas. Similarly, rivers can vary from small streams to massive waterways like the Amazon River, which is one of the world's largest rivers by discharge volume.
Shallow bodies of water, like ponds and many rivers, are often influenced by surface temperatures and receive more light, which affects the types of life that can thrive in them. On the other hand, deep bodies of water, like the Mariana Trench in the Pacific Ocean, plunge to incredible depths where conditions are vastly different from the surface.
