Daily Current Affairs Quiz: January 22, 2026

Statement 1 is correct: The Coriolis force depends on latitude; it is zero at the equator where Earth’s rotational effect is absent and progressively increases toward the poles, becoming maximum at the poles.

Statement 2 is correct: Due to Earth’s rotation, moving air, water, or objects are deflected to the right of their path in the Northern Hemisphere and to the left in the Southern Hemisphere.

Statement 3 is correct: The Coriolis force alters the direction of winds and ocean currents, playing a key role in the formation of planetary wind belts, cyclones, and ocean gyres.

Statement 1 is correct: Isotherms are imaginary lines drawn on maps connecting places that record the same temperature at a particular time or over a specified period.

Statement 2 is correct: Isotherms broadly follow latitudinal east–west patterns but are distorted by differential heating of land and sea, altitude variations, prevailing winds, and warm or cold ocean currents.

Statement 3 is incorrect: Closely spaced isotherms represent a steep or high temperature gradient, indicating rapid temperature change over short distances, not a low gradient.

Statement 1 is correct: Jet streams are narrow, meandering bands of very strong winds located near the tropopause in the upper troposphere, generally between 9 and 14 km above the Earth’s surface.

Statement 2 is incorrect: Jet streams are not permanent; their position, intensity, and latitudinal extent vary significantly with seasons due to changing temperature gradients between different air masses.

Statement 3 is correct: Jet streams predominantly flow from west to east because of pressure gradient force and Coriolis force arising from Earth’s rotation.

The eastward flow of the equatorial counter-current is explained by the convergence of the two equatorial currents:

• The North Equatorial Current flows westward north of the equator.
• The South Equatorial Current flows westward south of the equator.

Their convergence leads to piling up of warm surface water in the western parts of ocean basins, creating an eastward pressure gradient.

This pressure gradient drives the eastward-flowing Equatorial Counter-Current.

Statement 1 is correct: The Sun’s gravitational force influences tides by exerting a pull on Earth’s oceans; although weaker than the Moon’s effect, it significantly contributes to spring and neap tides.

Statement 2 is correct: The Moon’s gravitational force is the primary cause of tides due to its proximity to Earth, creating tidal bulges on the side facing the Moon and the opposite side.

Statement 3 is correct: The centrifugal force of the Earth–Moon system, arising from their mutual rotation around a common barycentre, produces a tidal bulge on the side opposite to the Moon.
