Final answer:
Grape varieties differ between northern and southern regions due to climate and soil; southern areas like the Mediterranean are ideal for grapes used in wine, whereas northern areas focus on wheat and dairy due to cooler, wetter climates.
Step-by-step explanation:
The types of grape varieties that are more predominant vary significantly between the northern and southern regions of countries, largely due to differences in climate and soil conditions. For example, in the southern regions of France, hot and dry climates are ideal for growing grapes used in wine production, as well as other fruits and vegetables. This is also evident in the Mediterranean areas known for their grape cultivation. Conversely, in regions like northern France and other cooler climates, the grape varieties may differ, and there is more focus on crops like wheat, dairy products, and cattle grazing due to the wetter climate and grasslands more suitable for these types of agriculture.
