Mud
Mud is a mixture of soil and or silt or clay, that, when mixed together with water, becomes a thick liquid. Creepy crawly things like to make muddy places their home.
Some of these little creatures, like snails, frogs and worms, thrive in the warm, moist and thick mud. Muddy water also provides other larger creatures, such as elephants and pigs, with the ideal place to take a bath. This cools the animals down and helps provide them with protection from the sun.
However mud can also be dangerous, two examples of this are, firstly, when mud roads are subject to too much rainfall or, secondly, when the formation of mud volcanos takes place. Both situations can be hazourdous.
