The answer is soil degradation. It is an artificial evolution related to the local climate and vegetation. It is caused by the replacement of primary plant communities (known as climax) by the secondary communities. This replacement changes the humus composition and quantity, and affects the formation of the soil. It is directly related to human activity. Soil degradation may also be defined as any change or disturbance in the soil perceived to be deleterious or undesirable. In this question, the more the farmer worked, the more he incidentally changed the formation and structure of the soil which resulted in the decrease in his crop yield.
Answer :
are techniques for conserving soil resources and fertility
Explanation :
In simple words, Planting multiple crops in appropriate combinations throughout the identical field is known as intercropping. Crop rotation is the process of changing the crops cultivated on a farm from one harvest to the next. On steep hillsides, terracing provides flat floors for plants to collect rainfall and decrease desertification.
The correct answer is - b. African.
The African tectonic plate will move the most of all tectonic plates. It is moving into a northeastern direction, and it is pushing towards the western part of the Eurasian tectonic plate and it is squeezing the Arabian tectonic plate between itself and the Eurasian tectonic plate. Because of this movement, the African tectonic plate in a relatively small amount of time (geologically speaking) will merge with Europe, and since both of the plates are of same density a large mountain range will start to form because of the pressure between the two plates. Also, the Mediterranean Sea will be cut of from the Atlantic Ocean and it will dry out.

Answer:
Upwelling, the rising of water from deeper layers of the ocean, is a wind-induced movement that brings cold and nutrient rich water to the surface.
Explanation:
Marine resurgence is an oceanographic phenomenon that occurs when subsurface waters rise. These waters consist of a large amount of nutrients and have a lower temperature than surface waters, becoming colder. This phenomenon generally occurs in areas where primary production is high, or when there is strong fishing activity in the region.
