• how does a sponge hold water if its full of holes?🤔

Is a leaf called a leaf cause it leaves the tree?🤔
• Great questions!

1. A sponge can hold water despite being full of holes because of the properties of the material it's made of. A sponge is made of a porous material that absorbs water due to capillary action. This means that the tiny holes or pores in the sponge create a network of small tubes that draw in and hold water. When a sponge is squeezed, the water is forced out of the pores, but when it's released, the sponge regains its shape and can hold water again.

2. The word "leaf" actually has its roots in an old English word "leafan" which means "to leaf or to grow leaves". The word "leaf" refers to the flattened structure attached to a tree or plant that is used for photosynthesis and respiration. So, a leaf is called a "leaf" because that's what it is and what it does, not because it "leaves" the tree. However, the word "leave" as in "to leave the tree" does come from a different word, "lafian", which is also an old English word that means "to allow to remain, leave behind".
