The correct answer is - A. replacing natural vegetation with cultivated crops.
The natural vegetation is perfectly adapted to a certain environment, and it is also able to keep the soil tight with its roots, so the erosion is minimal.
When the natural vegetation is replaced by cultivated crops, than a problem occurs in the erosion of the soil. That is because the cultivated crops, in general, do not have root systems that are as strong and widespread as the natural vegetation, thus the soil becomes loosened up, so it is much easier to be eroded.
Answer:
As a result, the orientation of Earth's axis to the sun is always changing throughout the year as we revolve around the sun. Sometimes the axis points toward the sun and other times away from the sun. ... This causes a seasonal variation in the intensity of sunlight reaching the surface and the number of hours of daylight.

Answer:
The Southern Colonies had fertile soil and had a flatter geography.
The New England Colonies in the North had rocky soil and had hills/mountains inland which made them more on the industry side (this is also how the Union won the Civil War later on, the North was able to manufacture things while the South had mostly agricultural plantations). There wasn't much use for slaves in a factory, and much more in the South where plantations and large farms were.
The North was very religious besides Pennsylvania where the Quakers resided.
The South barely was religious because your nearest neighbor would be a few farms over, so you don't really converse with them much.
