Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Jupiter revolves or orbits around the Sun once every 11.86 Earth years, or once every 4,330.6 Earth days. Jupiter travels at an average speed of 29,236 miles per hour or 47,051 km per hour in its orbit around the Sun.
Hence, the planet Jupiter takes 12 years to go around the Sun.

On which two days does the Sun rise exactly in the East?

  1. April 21, July 23

  2. March 21, September 23

  3. March 23, September 21

  4. June 21, December 22
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

From summer solstice (June 21), the Sun starts moving towards the South and from winter solstice (December 22), the Sun starts moving towards North. So during summer solstice, it is in the south eastern part and in winter solstice it is in the north eastern part. However, there are 2 days, i.e., March 21 and September 23, when the Sun rises exactly in the East.

Why does Venus show phases like the moon?

  1. It rotates from East to West

  2. It is covered by clouds

  3. Its atmosphere is dense

  4. None of the above
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Just like moon, Venus too rotates from East to West. Thus, only that part of Venus is visible to us which reflects the light from the Sun towards us. Hence, the Venus appears to show phases because the Earth and Venus rotate in opposite direction.

Days and nights are caused by

  1. rotation of the Earth

  2. revolution of the Earth

  3. both rotation and revolution of the Earth

  4. neither rotation nor revolution of the Earth
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

As earth is rotating on its own axis so its half part is exposed to sun cause day at that part and hidden half part suffers from darkness called night.

Multiple choice geography environmental changes elements of weather and climate : temperature process of heat transfer in the atmosphere environmental regions (zones)

The sun's energy is dissipated and scattered before it reaches the ______.

  1. mars

  2. pluto

  3. moon

  4. earth
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Earth,

Once the sun's energy reaches earth, it is intercepted first by the atmosphere. A small part of the sun's energy is directly absorbed, particularly by certain gases such as ozone and water vapor. Some of the sun's energy is reflected back to space by clouds and the earth's surface.

What factors are responsible for Insolation variation?

  1. The angle of inclination of the suns rays

  2. The length of the day

  3. The transparency of the atmosphere

  4. all of these
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The conditions of the atmosphere as well as the seasons affect the actual amount of insolation received at a place on the earth. Following are the factors which are responsible for variation in insolation:-

  1. Angle of inclination of the sun rays
  2. Length of the day
  3. Transparency of the atmosphere
  4. Solar constant
  5. Distance between the earth and the sun

In the Northern Hemisphere, this day has the fewest hours of daylight:

  1. Summer solstice

  2. Winter solstice

  3. Vernal equinox

  4. Autumnal equinox
Reveal answer Fill a bubble to check yourself
