The question asks about the direction of deflection of winds due to the Coriolis effect, which is caused by Earth's rotation. Understanding the Coriolis effect and its manifestation in different hemispheres is key to answering this question.
C) To the right in Northern Hemisphere, to the left in Southern Hemisphere — This statement accurately describes the direction of deflection of winds due to the Coriolis effect in both hemispheres.
The question asks about the geographical factor responsible for time differences due to Earth's rotation. We need to understand how Earth's rotation affects the perception of time across different locations on its surface.
Correct Option: A) Longitudes — Earth's rotation directly causes a difference in local time between places situated at different longitudes. As the Earth spins, different longitudes come into direct alignment with the Sun at different moments, leading to variations in time.
To understand what a 'Solar Day' is, we need to consider Earth's rotation relative to the Sun. This is distinct from Earth's rotation relative to distant stars (sidereal day) and its revolution around the Sun.
Correct Option: B) Time taken by Earth to complete one rotation relative to the Sun
The question asks about the primary cause of the 'tidal bulge' phenomenon on Earth. This involves understanding the gravitational interactions between celestial bodies and Earth's motion.
Correct Option: A) Gravitational pull of the Moon and Earth's rotation. This option correctly identifies the two primary factors responsible for the tidal bulges and the phenomenon of tides.
The shape of the Earth is influenced by its rotation. We need to understand how rotational forces affect a celestial body's shape to determine the correct option.
Effect of Rotation: When an object rotates, points farther from its axis of rotation experience a greater centrifugal force. This force acts outwards, away from the axis of rotation.
Earth's Rotation: The Earth rotates on its axis. The equator is the farthest point from the axis of rotation, while the poles are directly on the axis.
Centrifugal Force Distribution: Due to Earth's rotation, the centrifugal force is strongest at the equator and weakest (zero) at the poles. This outward force causes material to bulge at the equator.
Resulting Shape: This bulging at the equator and flattening at the poles results in a shape known as an oblate spheroid. An oblate spheroid is essentially a sphere that is slightly flattened along its axis of rotation and bulges around its equator.
Correct Option: B) Oblate spheroid (flattened at poles, bulging at equator)
The Earth's rotation creates a centrifugal force that is maximum at the equator and zero at the poles. This force causes the Earth to bulge outwards at the equator and flatten at the poles, resulting in an oblate spheroid shape.
The question asks for the approximate location of the International Date Line. This is a fundamental concept in geography related to time zones and global navigation. Understanding the Earth's spherical nature and the system of longitudes is key to identifying this line.
A) 180° longitude — The International Date Line is approximately located along the 180° longitude. This meridian is diametrically opposite to the Prime Meridian (0° longitude) and is where the calendar day officially changes.
