  2. Comparatively cooler regions

  3. Granulation's

  4. Cloudy weather on the earth
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Sunspots are temporary phenomenon on the sun photosphere that appears as spots darker than the surrounding area.

They are regions of reduced surface temperature. 
Answer is $B$

Multiple choice physics life cycle of stars evolution and end stages of stars the stars stars

The constellation of stars appear at different positions in the sky at different times during night mainly ________________________.

  1. Because earth rotates about its axis

  2. Because Earth revolves round the sun

  3. Because of optical illusion

  4. Because celestial bodies are changing their positions all the time
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The apparent motion of stars and constellations across the sky during the night is primarily caused by the rotation of the Earth on its axis, which makes the celestial sphere appear to rotate in the opposite direction.

Multiple choice social studies precautions for natural disasters cyclonic winds monsoon phenomena and its mechanism tsunami, floods, cyclones, droughts and landslides

The rotation of earth affects the direction of _________.

  1. Cyclone

  2. Anticyclone

  3. Both a and b

  4. None of these
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

In the absence of rotation, the wind tends to blow from areas of high pressure to areas of low pressure. The stronger the pressure differences between a high-pressure system and a low-pressure system, the stronger the wind. The coriolis force caused by Earth's rotation gives winds within high-pressure systems their clockwise circulation in the northern hemisphere as the wind moves outward and is deflected right from the center of high pressure and anticlockwise circulation in the southern hemisphere as the wind moves outward and is deflected left from the center of high pressure. Friction with land slows down the wind flowing out of high-pressure systems and causes wind to flow more outward from the center.

Multiple choice free, damped and forced oscillations free, forced and damped oscillations oscillations oscillation and waves physics

The orbital motion of the earth, around the sun is 

  1. periodic but not oscillatory

  2. oscillatory but not periodic

  3. neither periodic not oscillatory

  4. both periodic and oscillatory
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The orbital motion of the earth around the sun is not an oscillatory motion as it is not a two and fro motion about a mean position. But it is a periodic motion.

Multiple choice political science transgender / third gender transgender achieving equality moving towards equality

Among these, which are nature laws?

  1. Rising and setting of the sun, phases of moon

  2. Change in the seasons

  3. Law of gravity

  4. All of above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Natural occurrences follow nature laws. We cannot change the laws of nature. The rising and setting of the sun and the change in the seasons never stop. The law of gravity does not change. The rising and falling of tides, the phases of moon all of these occur according to the laws of nature.
