Climate:
The Fertile Crescent has a Mediterranean climate with hot, dry summers and mild, wet winters. This climate is ideal for growing a variety of crops, including wheat, barley, lentils, and chickpeas. In contrast, Northern Europe has a cold, temperate climate with long, harsh winters and short, cool summers. This climate is not conducive for growing crops and makes it difficult for humans to survive.
Water:
The Fertile Crescent is home to some of the world's major rivers, including the Tigris, Euphrates, and Nile Rivers. These rivers provided a steady source of water for drinking, irrigation, and transportation. In contrast, Northern Europe has a number of small rivers and lakes, but they are not as reliable as the rivers of the Fertile Crescent.
Land:
The Fertile Crescent has a relatively flat and fertile land that is easy to cultivate. In contrast, Northern Europe is covered in forests and mountains, which makes it difficult to clear land for agriculture.
Resources:
The Fertile Crescent is rich in natural resources, including flint, obsidian, and copper. These resources were used to make tools, weapons, and other objects essential for survival. In contrast, Northern Europe has few natural resources and is not as well-suited for human habitation.
Therefore, the combination of favorable climate, water, land, and resources made the Fertile Crescent a much more attractive region for early human migration than Northern Europe.
