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.

Iron Age
|
About 800 BC to 43 AD
The Iron Age comes after the Bronze Age and before the Roman period. It is a time when people developed the skills and knowledge to work and use iron, hence the name ‘Iron Age’ which is given to this period.
