At which place does the length of shadow at noon remain same throughout the year?

  1. The North Pole

  2. The South Pole

  3. The Equator

  4. The Tropic of Capricorn
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

At the equator, the sun is directly overhead at noon during the equinoxes, and the variation in the sun's angle throughout the year is minimal compared to other latitudes, leading to consistent shadow lengths.

The scientists discovered that the earth is _____ in shape.

  1. Round

  2. Spherical

  3. Oval

  4. Square

B Correct answer
Explanation
Exploration is the act of searching for the purpose of discovery of information or resources. Exploration occurs in all non-sessile animal species, including humans. In human history, its most dramatic rise was during the Age of Discovery when European explorers sailed and charted much of the rest of the world for a variety of reasons. Since then, major explorations after the Age of Discovery have occurred for reasons mostly aimed at information discovery.

In scientific research, exploration is one of three purposes of empirical research (the other two being description and explanation). The term is commonly used metaphorically. For example, an individual may speak of exploring the Internet, sexuality.
Multiple choice physics our solar system planets of the solar system solar system and sun introduction to solar system

The mean distance between the Earth and Sun as well as the distances within the solar system is represented by

  1. light year

  2. astronomical units

  3. parsec

  4. Angstrom
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The mean distance between the Earth and Sun as well as the distances within the solar system is represented by astronomical units.
One astronomical unit (AU) represents:
1 AU = 149,597,870.700 kilometers (or 149,597,870,700 meters)
An astronomical unit is the mean distance between the Earth and the Sun.

Multiple choice physics our solar system planets of the solar system solar system and sun introduction to solar system

If the axis of rotation of the earth were extended into space then it would pass close to

  1. The moon

  2. The sun

  3. The polar star

  4. The centre of mass of all the planets in the solar system
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

A pole star is a visible star, which lies approximately directly overhead when viewed from earth's north pole or south pole. In practice the term pole star usually refers to polars, which is the current northern pole star, also known as north star. The south celestial pole lacks a bright star like polarise to mark its position.

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

Into how many temperature zones the earth can be divided?

  1. Two

  2. Three

  3. Four

  4. Five
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The earth can be divided into four temperature zones. They are, 

1. Torrid zone:  It extends on both sides of the equator bounded by the tropic of cancer and tropic of Capricorn. In this area sun's rays are more or less perpendicular. The temperature in this area is always high.
2. North Temperate zone: This area is between tropic of cancer and Arctic circle in the northern hemisphere. Sun rays do not fall perpendicularly nor slanting at this place. So places within this area neither too hot not too cold.
 3. South Temperate zone: This area is between the Tropic of Capricorn and Antarctica circles. Here temperature is neither too hot nor too cold.
4. Frigid zone: The frigid zone in the northern hemisphere lies Arctic circle and the North Pole and in the southern hemisphere between Antarctic circle and south pole. They receive very little heat from the sun and hence very cold.

Multiple choice geography pressure belts and winds pressure belts elements of weather and climate :rainfall and air pressure monsoon phenomena and its mechanism

Equatorial low pressure belt exists between _________________.

  1. $10^0N-10^0S$
  2. $5^0N-5^0S$
  3. $15^0N-15^0S$
  4. $5^0N-15^0S$
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation
$5^0 N - 5^0 S$
This low pressure belt is also called as doldrums, because it is a zone of total calm without any breeze. 
Subtropical High Pressure Belts. At about 30°North and South of Equator lies the area where the ascending equatorial air currents descend.

'Horse Latitudes' is a geographical name of __________________.

  1. High pressure areas $30^{\circ}N$ and $30^{\circ}S$
  2. Areas which lie between $5^{\circ}N$ and $5^{\circ}S$ of equator

  3. Equatorial doldrums

  4. Polar regions
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The Horse Latitudes are subtropical high-pressure belts located between 30 and 35 degrees north and south of the equator, characterized by calm winds and dry weather.

Multiple choice geography atmosphere and climate pressure belts elements of weather and climate :rainfall and air pressure monsoon phenomena and its mechanism

Earth rotates from ______________.

  1. East to west

  2. West to East

  3. North to South

  4. South to North
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

West to East,

Earth's rotation is the rotation of Planet Earth around its own axis. Earth rotates eastward, in prograde motion. As viewed from the north pole star Polaris, Earth turns counterclockwise.
Because Earth rotates on its axis from west to east, the Moon and the Sun (and all other celestial objects) appear to move from east to west across the sky. Viewed from above, however, the Moon orbits Earth in the same direction as our planet rotates.
