The question asks about the general direction of 'Polar Easterlies'. To answer this, we need to recall the global pressure belts and the effect of the Coriolis force on wind direction in both hemispheres.
Correct Option: C) East towards the west
The question describes a phenomenon where moving objects, particularly winds, are deflected due to Earth's rotation. We need to identify the scientific principle that explains this deflection, specifically the rightward deflection in the Northern Hemisphere and leftward in the Southern Hemisphere.
B) Coriolis Effect (Force) is the apparent force that deflects moving objects (like winds and ocean currents) on the Earth's surface due to the planet's rotation. It causes deflection to the right in the Northern Hemisphere and to the left in the Southern Hemisphere, precisely as described in the question.
The question asks for the fundamental reason behind Ferrel's Law, which describes the deflection of winds due to the Coriolis effect. We need to identify the primary force or phenomenon responsible for this effect.
B) Earth's rotation on its axis is the fundamental reason for the Coriolis effect and, consequently, Ferrel's Law. The Earth's rotation creates an inertial force that deflects moving objects (like winds and ocean currents) to the right in the Northern Hemisphere and to the left in the Southern Hemisphere.
The question asks to identify the term for the equatorial belt characterized by calm, light, and variable winds, associated with the rising air of the Equatorial Low-pressure zone. This requires knowledge of global wind patterns and pressure belts.
A) Doldrums — This term accurately describes the equatorial belt (roughly between 5° North and 5° South latitude) where the air is warm, moist, and rising, leading to low pressure, calm conditions, and light, variable winds. This region is also known as the Intertropical Convergence Zone (ITCZ).
The question asks to identify the specific atmospheric belt characterized by calm winds and descending, stable air, located around 30 degrees North and South latitude, which historically caused problems for sailing ships. This description points to a well-known geographical and meteorological phenomenon.
B) Horse Latitudes — The Horse Latitudes are subtropical regions at approximately 30-35 degrees North and South latitude, characterized by calm winds and high atmospheric pressure. This is due to the descending air of the Hadley Cell, which creates stable atmospheric conditions. Historically, sailing ships carrying horses would often get stuck in these calm waters, leading to the name as horses were sometimes thrown overboard to conserve water. The description perfectly matches the characteristics and historical context provided in the question.
The question asks to identify the specific name for the strong, persistent westerly winds found in the Southern Hemisphere between approximately 40 and 50 degrees South latitude, which are known for their strength due to the uninterrupted ocean expanse. This requires knowledge of global wind patterns and their regional names.
B) Roaring Forties — This term specifically refers to the strong westerly winds found in the Southern Hemisphere, particularly between 40°S and 50°S latitude. The lack of landmass in these latitudes allows these winds to blow with exceptional strength and persistence, hence the name "roaring."
