Answer:
To prevent obstruction of rain drops.
Explanation:
The answer is true; I hope this helped
Answer and Explanation: Differences between members of the same species are called genetic variations. ... Each member of the species will have a slightly different combination of alleles thanks to genetic variation. Genetic variation is what makes individual humans so unique, even though we all belong to the same species.
The drainage area is not an important factor in determining stream discharge because it is not the main force behind stream discharge.
<h3>What is a
stream discharge?</h3>
This refers to the volume of water that flows through a stream or river per unit of time.
This discharge are usually calculated by using the measurements of the stream’s velocity, its depth and width
The factors that affect stream discharge includes:
- velocity of the water because the faster the water, the more the discharge
- the width & depth of the river

A tropical cyclone (TC) is a rotational low-pressure system in tropics when the central pressure falls by 5 to 6 hPa from the surrounding and maximum sustained wind speed reaches 34 knots (about 62 kmph). It is a vast violent whirl of 150 to 800 km, spiraling around a centre and progressing along the surface of the sea at a rate of 300 to 500 km a day.
The word cyclone has been derived from Greek word ‘cyclos’ which means ‘coiling of a snake’. The word cyclone was coined by Heary Piddington who worked as a Rapporteur in Kolkata during British rule. The terms "hurricane" and "typhoon" are region specific names for a strong "tropical cyclone". Tropical cyclones are called “Hurricanes” over the Atlantic Ocean and “Typhoons” over the Pacific Ocean. The reason is that the earth's rotation sets up an apparent force (called the Coriolis force) that pulls the winds to the right in the Northern Hemisphere (and to the left in the Southern Hemisphere). So, when a low pressure starts to form over north of the equator, the surface winds will flow inward trying to fill in the low and will be deflected to the right and a counter-clockwise rotation will be initiated. The opposite (a deflection to the left and a clockwise rotation) will occur south of the equator.
This Coriolis force is too tiny to effect rotation in, for example, water that is going down the drains of sinks and toilets. The rotation in those will be determined by the geometry of the container and the original motion of the water. Thus, one can find both clockwise and counter-clockwise flowing drains no matter what hemisphere you are located. If you don't believe this, test it out for yourself.
