Okay kiddo, let me explain what suspended load means.
Imagine you are at the beach and you see some waves coming towards you. Do you see how those waves carry all those tiny sand particles in it? Those sand particles are called sediments.
Now, when the waves hit against the shore, they pick up some sediments and carry them along with the water. These sediments are floating in the water, not touching the bottom, and they look like they're flying. This is called suspended load. It's like when you hold a balloon and let go of it, and it goes up in the air.
Suspended load happens in rivers as well. When water flows through a river or a stream, it sometimes picks up sand, gravel, or even small rocks. These particles are light enough to float in the water, and they move along with the flow of the river without touching the bottom.
It's important to know about suspended load because it can affect the quality of the water. When water carries all those sediments, it can make it cloudy and muddy, and it can also cause erosion (when the water takes away pieces of the land). But, it can also be helpful because it can create new habitats for fish to live in, and it can even help with farming by depositing nutrient-rich sediment on the land.
So, that's suspended load in a nutshell. It's when water carries small particles (sediments) in it, and those particles float without touching the bottom.
