<em>Answer:</em>
<em>1. Drainage Systems have been created by humans to a short lag time and high peak discharge as water could not evaporate or infiltrate into the soil</em>
<em>2. area that have been urbanised result in an increase in the use of impermeable building materials</em>
Answer:
Explanation:
Banded iron formation ( BIF ) -
It is aslo called the banded inronstone formations , are the part of the distinctive units in the sedimentary rocks , which are always of the precambrian age .
volcanogenic massive sulfides ( VMS )-
A type of metal sulfide ore deposit , which have copper - zinc as the main elements , they are formed by in the submarine environments by the volcanic - associated hydrothermal events .
The types of VMS -
Mafic associated - The type of deposits associated with geological environments by mafic rocks.
Bimodal-mafic - The type deposits associated with environments dominated by mafic volcanic rocks.
Mafic-siliciclastic - The type deposits associated with sub - equal proportions of the siliciclastic and the mafia rocks .
Felsic-siliciclastic - The type deposits associated with less than 10 % mafic rock and rest siliciclastic sedimentary rock .
Bimodal-felsic The type deposits associated with more of felsic rocks than mafic rocks.
Answer:Disadvantages
It is less precise compared to other advanced methods of surveying.
It is easily subjected to various errors such as errors adjoining magnetic meridian, local attraction etc.
Imperfect sighting of the ranging rods and inaccurate leveling also causes error.
ADVANTAGES: Does not require any electrical power to function (except for night illumination), therefore is not affected by the loss of power. Tends to be more stable than a fluxgate compass. Usually, the bigger the compass card diameter on a magnetic compass, the more stable, (and also the easier to read)
