The use of chemical fertilizers in agriculture in the last few decades has led to a marked increase in agricultural production. The addition of chemical fertilizers to crops ensures that plants receive the correct formulation of nutrients that are necessary for growth. Plants will mature faster and produce more when this is done. Fertilizers also enable the use of agricultural lands to be ongoing as there is no need to rest the soil to allow nutrients to naturally build up. Growing can, therefore, be continuous all year round, leading to increased production.
Water cycle is effected by pollution, whether it is water pollution or air pollution. Air is polluted by Suspended Particulate Matter and by different harmful gases like Sulphur dioxide etc. These gases react with water vapours in the sky, making the water in the clouds acidic. This acid falls as rain water causing acid rains. This acid falls in ponds, on land, in fields, causing harm to us and to the crops as well as to the fishes or creatures in water. When the water evaporates from ponds, rivers and oceans to make water vapour, the the water in these water bodies becomes more acidic, and again when acid rains occur, this acid again mixes with the water of the water bodies, which already has acid, causing the water to become more concentrated.
Answer:
d. Reverser Hierarchical
Explanation:
Expansion diffusion is said to be when a particular trend is spread from it originating point to another point. It might be relocation diffusion whereby a relocating resident share his idea and practice to his/her new residence.
Hierarchical diffusion occur when a new cultural practice is shared to another people. Like in the case of Africa's adapting to white pattern of dressing.
Contagious diffusion is a kind of virus trend like in Nigeria where a dance pattern is transfer to a neighboring country like Ghana.
Stimulus diffusion occur when a people adapt an idea from another and modify it. Example ping pong(Table tennis) originating from Asia and modified by another .
Reverser Hierarchical is not a form of expansion diffusion
Answer:
In the ocean where new crust is being created at a divergent plate boundary.
Explanation:
The crust mainly form the bottom of the oceans which is constantly forming along the mid oceanic ridges.The mid ocean ridge is the boundary between tectonic plates and it is the place where the plates spreads apart from each other.
The hot magma in the underlying layer gradually cools down and transform into a solid form which ultimately form the new ocean crust that gradually pushed away from the ridge by more new crust.
This spreading produce upto 2-6 inches of new crust per year.
The Equator divides the south and the north pole so they cant be conjoined
