The statement that weathering occurs as a result of direct contact with the atmosphere is true. Weathering is a process by which rocks are broken down by direct contact with the atmosphere which is caused by exposure to heat, ice, and elements in the atmosphere. Two type of weathering are: Physical and Chemical weathering.Physical weathering occurs when rocks, soil, or minerals are broken down through mechanical means.Chemical weathering occurs when rocks, soil, or minerals are broken down through reactions with chemicals that are in the air or are biologically introduced.
(I'll answer the last question first)
The diffusion of agriculture, as theorized by Carl Sauer, a cultural geographer, notes that the earliest form of agriculture was vegetative planting. Then the process of seed planting occurred some time later. After the early human settlement has developed more of farming methods.
Vegetative planting is characterized by cutting the stems of a plant, or dividing part of its roots and transplanting them into soil. This was believed to be the first method, as it was in this method the early human tried to wild plants nearer to their settlements for easier access to food.
While on the other hand, Seed planting was a newer technology for the early humans. It involves the collection of the fruit and drying of seed to be planted. It is also happen in annual basis unlike the transfer of stems and roots of wild plants.
