Geophysical Survey
|
The measuring and recording of electrical resistivity or magnetism in order to determine the existence and outline of buried features such as walls and ditches. Geophysical techniques include resistivity survey, magnetometer survey and ground penetrating radar.

Cropmark
|
Cropmarks appear as light and dark marks in growing and ripening crops. These marks relate to differences in the soil below. For example, parched lines of grass may indicate stone walls. Crops that grow over stone features often ripen more quickly and are shorter than the surrounding crop. This is because there is less moisture in the soil where the wall lies.

|
A small regular hole that is usually square or rectangular in shape. Archaeologists dig trial trenches to discover if there are any archaeological remains at a particular location. See also excavation.

Aerial Photograph
|
Aerial photographs are taken during an aerial survey, which involves looking at the ground from above. It is usually easier to see cropmarks and earthworks when they are viewed from above. Aerial photographs help archaeologists to record what they see and to identify new sites. There are two kinds of aerial photographs; oblique and vertical.

Modern
|
The Modern Period, about 1915 AD to the present (the 20th and 21st centuries AD)
In recent years archaeologists have realised the importance of recording modern sites. They do this so that in the future people will be able to look at the remains to help them understand the events to which they are related.

Prehistoric
|
About 500,000 BC to 42 AD
The Prehistoric period covers all the periods from the Palaeolithic to the end of the Iron Age.
This is a time when people did not write anything down so there is no documentary evidence for archaeologists to look at. Instead, the archaeologists look at the material culture belonging to the people and the places where they lived for clues about their way of life.
The Prehistoric period is divided into the Early Prehistoric and Later Prehistoric.
The Early Prehistoric period covers the Palaeolithic and Mesolithic periods.
The Later Prehistoric period covers Neolithic, Bronze Age and Iron Age times.

Mesolithic
|
About 10,000 BC to 4001 BC
Mesolithic means 'Middle Stone Age'. It is the period that comes between the Palaeolithic (Old Stone Age) and the Neolithic (New Stone Age).
The Mesolithic period is a period of transition from the way people were living during the Palaeolithic period as hunter-gatherers to the development of farming in the Neolithic period.

Neolithic
|
About 4000 BC to 2351 BC
The word ‘Neolithic’ means ‘New Stone Age’. Archaeologists split up the Neolithic period into three phases; early, middle and late. The Neolithic period comes after the Mesolithic period and before the Bronze Age.
People in the Neolithic period hunted and gathered food as their ancestors had but they were also began to farm. They kept animals and grew crops. This meant that they were able to settle more permanently in one location instead of constantly moving from place to place to look for food.
