A a landform that is naturally lower than its surroundings
<u>Explanation:</u>
Botswana is an African nation where over 23% of population is infected with HIV. The government introduced prevention, treatment and testing strategy to address this serious issue. The goal of this program is to bring HIV infections under control in the country and reduce the chances of further infections.
According to the ‘treat all’ program every person who is tested to be <em>HIV positive</em> is given immediate treatment. All infected persons are given free Anti Retroviral Treatment for a lifetime. The government’s active measures could successfully reduce the infections that spread from affected mother to infants.
Testing measures have changed form from voluntary testing to routine testing and then to compulsory testing. Compulsory testing is sometimes blamed for increasing the stigma about the disease. But these measures help the people to know their status and reduce the number of people living without knowing they are HIV positive.
B) Materials in Solution is NOT a process of a stream load
Streams must start somewhere. Streams are formed by having
sufficient water supply. The supply comes from rainfall and
underground reservoirs. The area that initiates the stream
supply is called the headwaters. Many times headwaters start
in the high elevations. As the water moves down through the
mountains, the stream’s pathway is formed. As streams evolve, the path of the stream starts to curve. The
curving of a stream channel is known as a meander. As meanders
develop, they become broader and larger. Eventually,
there are enough material deposits to form a blockage of two
meanders. This development causes the formation of an
oxbow lake.
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.
