Assim como o nosso
corpo, o solo também tem uma organização. Para podermos entender esta
organização, primeiro vamos imaginar um bolo de aniversário que tem várias
camadas, uma em cima da outra, como: uma camada de chocolate, uma de morango e
uma de baunilha. O solo também tem as suas camadas que são chamadas de horizontes
do solo. 

O solo tem &nbsp;diferentes camadas do solo, sendo cada uma de
uma cor diferente. Estas camadas são os horizontes do solo, assim como
as camadas do bolo de aniversário. 

Estes horizontes podem apresentar cores
diferentes, como nas fotos ou não. Quase sempre o primeiro horizonte é mais
escuro que os outros. Isso porque é nele onde normalmente plantamos os nossos
vegetais.&nbsp; 
Os vegetais (frutas,
verduras, legumes e árvores) e os pequenos animais quando morrem vão se
misturando com este primeiro horizonte dando a ele uma cor escura.
