The answer is Gully Erosion. It is known as the least common yet would cause the most dramatic visible change in the landscape. The cuts that are deep in the soil would leave large gullies that would expand through erosion.
Answer:
geomagnetic field.
Explanation:
The earth magnetic field can be likened to a bar magnet with a North and South pole. It originates from the movement of molten iron and nickel in the outer core.
At every point in time, the magnetic field orientation can change. We must note that the magnetic north lies close to that of geographic north axis of the earth.
Around the mid-oceanic ridges, new materials are brought to the surface. These new materials can contain magnetic minerals such as haematite which are capable of being magnetized as a result of the prevalent magnetic field of the earth. As different materials are brought up, the magnetic minerals preserves the details of the magnetic field at that point in time. Using this information can know the orientation of the magnetic field at any point in time if the magnetic history chart of the earth is constructed. Oceanic ridges becomes older as they move away from the divergent margins.
<span>Fresh water is a natural resource while is steadily declining, most prominently in areas such as Asia and North America. There is roughly 326 million trillion gallons of water on this earth however only 3% is drinkable, fresh water. The most significant use of water is to produce hydropower through harnessing its energy, however fresh water is also extracted for consumption, farming and many other daily chores. According to experts, when the annual water supply drops below 1000 m3 per person, this is when the population of that area faces water scarcity. It is predicted that by 2025, most countries within Africa will face this extreme water scarcity as a result of an increasing population and therefore increased water demands. Humans can limit their consumption by conserving fresh water for uses outside of consumption. Water is renewable through rain however we are depleting it at rate in which is cannot be sustained.</span>
Answer:
While historians specifically focus on history, their studies can include studying religious or philosophical changes over time and how those things affected society. Geographers are concerned specifically with the earth and the relationship it has with living organisms.
