Archaeology is the study of the past by finding the remains left by people who lived in the past. Archaeologists try to work out what the remains mean. These are called "artifacts", and can include old coins, tools, houses, or even people's garbage.
To find the old remains, archaeologists often dig holes to find things that are buried. This is called fieldwork. Old things become buried over time, because of things that happened later. People's garbage can pile up on top, or soil can be pushed down the hill to cover older things.
Sometimes archaeologists find the bones of dead people and the things ay used, or the houses ay lived in. Archaeologists think it is important to understand the past, because so many people use the past to know where ay come from.
There are many kinds of archaeologists who work in different places. Some archaeologists study Ancient Egypt, while others study old Greece or the Vikings. Archaeologists study every civilization that is known, especially the ones where are is no history to read. They study remains of hominids who ay think lived 3 million years ago in Africa, but ay also study places from World War II.
Stonehenge Sometimes new sites are found when new buildings are constructed. Archaeologists want to dig up and study ase sites so that ay are not lost or covered up.
