How does freshwater mix with saltwater?

By binding with salt ions, causing them to sink.

What creates the boundary between freshwater and saltwater?

Different densities, temperatures, saltiness, and materials.

Due to the mixing of freshwater and saltwater.

The different densities, temperatures, saltiness, and materials.

By mixing due to different properties.

The video of the Fraser River meeting the Strait of Georgia showcases a fascinating phenomenon where freshwater and saltwater mix, creating a distinct boundary due to their varying densities, temperatures, and salt content. This blending occurs beneath the surface, with suspended sediments from the river water binding with salt ions in the seawater, causing them to sink and clear the water, highlighting the complex interplay of different elements in nature.
Despite the apparent visual separation of the two bodies of water, the Fraser River and the Strait of Georgia are not truly distinct entities but rather a dynamic interaction of different properties, much like oil and water that do not mix but still coexist. This phenomenon serves as a reminder of the intricate relationships between various components of nature, showcasing how diverse elements can interact and influence each other in unexpected ways.

The footage shows the Fraser River meeting the Strait of Georgia in Vancouver, Canada, where freshwater full of silt mixes with denser saltwater, creating a distinct boundary that appears as two separate bodies of water. The suspended sediments in the river water bind with salt ions in the seawater, causing them to sink and clear the water, forming a sharply defined mixing zone under the surface. Despite the appearance of an impenetrable boundary, it is actually a mixing of the two waters due to their different densities, temperatures, saltiness, and materials, akin to how oil and water don't mix but still blend.
