Why upthrust is important to the whale and why the whale gets into trouble when it is beached?

Well, friend, upthrust is what helps our gentle whale friends stay afloat effortlessly in the vast ocean. When a whale is beached, it loses this upthrust and its weight presses down on its organs, making it hard for them to breathe and survive. It's a sad situation, but with gentle care and help from kind humans, we can guide these magnificent creatures back to safety in the ocean where they belong.
