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.

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.

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.
