<span>Subsistence farming involves farmers growing just enough food that will be adequate for them and their families. So no surplus is farmed for sale. The Green Revolution allowed larger crop yield for farmers by introducing resistance strains, fertilizers and pesticides. As you can imagine, the wide spread use caused a very negative impact on the environment. Subsistence farming was basically revamped by the Green Revolution to allow surplus be produced for sale in developing nations.</span>
Answer:
<u>Lower latitudes to higher latitudes i.e low pressure to high pressure.</u>
Explanation:
- As the pressure gradient is a force that is derived from the lower latitude to the upper latitudes in the form of pressure systems and the winds belts that arise from ITCZ zone thus there is an upwelling of warm and hot air from this region and goes upwards to the polar regions and in between from a convective cycle.
- There is a characteristic of this zone in the form of a vigorous thunderstorm over large bodies of the ocean. All this heating is derived due to the sun's rays fall directly over the equator.
- ITCZ being the doldrum zone or zone of calms sets the surface air to fly pass creating a frontal situation of the hot and cold air mass to interact and create eddies in the oceans.
When the earth's tectonic plates shift they move against each other causing an earthquake .
