The prime meridian is the line drawn north to south at 0° Longitude
When rocks form and cool, metal particles align according to the magnetic poles.
The metal particles are affected by the magnetism of the poles, more specifically the north pole which is the stronger magnetic field. The metal particles act like the needle in the compass and align themselves to the north pole.
The primary subsistence crop that is in danger due to soil erosion is : C. Corn
The more corn that grows within an area, the more likely that the soil's fertility in that area became reduced and the land became degraded because of the ploughing method that is used in the agricultural method
hope this helps
