The Challenge -  
 
 
Archaeologists dig below the surface to make their discoveries, but how did the objects they find get under the ground?

The objects could have been buried on purpose. For instance, sometimes when a person is buried in a grave or tomb, some of their belongings are put in with them. People also bury precious things to hide them.

But more often, the remains of buildings and any objects left in them can become covered by soil and rubbish.
