Why The World’s Oceans Are Changing Colour?

The world’s oceans are changing color because something is mixing into them, just like when you add food coloring to a glass of water.

Imagine your favorite drink, maybe it's juice or lemonade. If you pour in some blue food coloring, it turns blue. If you pour in red, it turns red. The ocean is like that big drink, and different things are going into it from the land and sky around it.

• Plankton, tiny living things that float in the water, can make the ocean look green or blue, depending on what kind of plankton is there.
• Sediment, like dirt or sand, can come from rivers and make the ocean look brown or yellow.
• Algae, a type of plant, can grow a lot and turn the ocean bright green.

Sometimes, these things mix together, just like when you drop multiple colors into water. That’s why we see different shades of blue, green, and even red in the ocean from space!
