The acceleration due to gravity at the equator – |
| A. | is less than that at the poles |
| B. | is greater than that at the poles |
| C. | is equal to that at the poles |
| D. | does not depend on the earth's centripetal acceleration |
| Answer» A. is less than that at the poles | |
|
Explanation: The gravity of Earth, denoted g, refers to the acceleration that the Earth imparts to objects on or near its surface. At latitudes nearer the Equator, the inertia produced by Earth's rotation is stronger than at polar latitudes. This counteracts the Earth's gravity to a small degree - up to a maximum of 0.3% at the Equator - reducing the downward acceleration of falling objects. The second major reason for the difference in gravity at different latitudes is that the Earth's equatorial bulge (itself also caused by inertia) causes objects at the Equator to be farther from the planet's centre than objects at the poles. |

Granite, quartzite areas have upstanding look because – |
| A. | mechanically weathered faster |
| B. | these rocks are resistant to all kinds of erosion |
| C. | these rocks are not easily eroded |
| D. | not easily worn down |
| Answer» D. not easily worn down | |
|
Explanation: Granite is high in quartz, a mineral very resistant to weathering. Similarly, quartzite is harder than steel. So, they are not easily worn down and give rise to upstanding mountains and hills (Environmental Biology by P.D. Sharma, p. 37). However, they are subject to differential weathering: a rock that is resistant in a climate dominated by chemical weathering may be weak where physical weathering process dominate, and vice versa. So quartzite, thoughhard and chemically inert, can be fractured by physical weathering. |

| B. | imaginary line passing round the Earth midway between North & South poles |
| C. | a belt (ring) around the planet Saturn |
| D. | axis of rotation of Earth |
| Answer» B. imaginary line passing round the Earth midway between North & South poles | |
|
Explanation: An equator is the intersection of a sphere's surface with the plane perpendicular to the sphere's axis of rotation and containing the sphere's center of mass. Notably, the Equator refers to the Earth's equator, per above: an imaginary line on the Earth's surface equidistant from the North Pole and South Pole, dividing the Earth into the Northern Hemisphere and Southern Hemisphere. Other planets and spherical astronomical bodies have equators similarly defined. The length of the Equator is roughly 40,075 kilometres. |

Tides in the sea have stored in them : |
| A. | Hydraulic energy |
| B. | Kinetic energy |
| C. | Gravitational potential energy |
| D. | A combination of all the above three forms of energy |
| Answer» C. Gravitational potential energy | |
|
Explanation: Tides are the rise and fall of sea levels caused by the combined effects of the gravitational forces exerted by the Moon and the Sun and the rotation of the Earth. Tidal barrages make use of the potential energy in the difference in height (or head) between high and low tides. When using tidal barrages to generate power, the potential energy from a tide is seized through strategic placement of specialized dams. When the sea level rises and the tide begins to come in, the temporary increase in tidal power is channeled into a large basin behind the darn, holding a large amount of potential energy. |

| C. | Trapping of solar energy due to atmospheric carbon dioxide |
| D. | Cultivation in green houses so as to check pollution |
| Answer» C. Trapping of solar energy due to atmospheric carbon dioxide | |
|
Explanation: The greenhouse effect is a process by which thermal radiation from a planetary surface is absorbed by atmospheric greenhouse gases such as Carbon dioxide, and is re-radiatedin all directions. Since part of this re-radiation is back towards the surface and the lower atmosphere, it results in an elevation of the average surface temperature above what it would be in the absence of the gases. Human activities, primarily the burning of fossil fuels and clearing of forests, have intensified the natural greenhouse effect, causing global warming. |
