Answer: Option B. -> is less than that at the poles
Answer: (b)
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.
Because the force due to the gravitational attraction between two bodies (the Earth and the object being weighed) varies inversely with the square of the distance between them, an object at the Equator experiences a weaker gravitational pull than an object at the poles.

Answer: Option D. -> Tectonic activities
Answer: (d)
Answer: (d)
Answer: Option C. -> Deserts
Answer: (c)
A mushroom rock also called a rock pedestal or a pedestal rock is a naturally occurring rock whose shape, as its name implies, strikingly resembles a mushroom.
Usually found in desert areas, these rocks are formed over thousands of years when wind erosion of an isolated rocky outcrop progresses at a different rate at its bottom to that at its top.

Answer: Option C. -> United States of America (USA)
Answer: (c)
Answer: (c)
Answer: Option B. -> Earth is titled towards the sun in the Northern Hemisphere
Answer: (b)The winter in the Southern Hemisphere occurs when the Northern hemisphere is tilted more toward the Sun. From the perspective of an observer on the Earth, the winter Sun has a lower maximum altitude in the sky than the summer Sun.
