Que 1. The Solar eclipse achieves totality only in limited geographical regions because,
a) The Earth isn’t a clean flat surface, however, has reviews and depressions.
b) The length of the shadow of the moon on earth is small in comparison to the go phase of the earth.
c) The trajectories of the earth across the solar and the moon across the earth aren’t ideal circles.
d) Sun rays can attain a maximum of the peripheral areas of the shadow of the moon because of an atmospheric refraction

Answer: The length of the shadow of the moon on earth is small in comparison to the go phase of the earth.
Explanation:
The length of the shadow of the moon is small in comparison to the go phase of the earth.

Que 2.  Who first claimed that the earth revolves spherically around the sun?
a) Sir Isaac Newton
b) Kepler
c) Copernicus
d) Ptolemy

Answer: Copernicus.
Explanation:
Copernicus became the primary individual who claimed the reality that Earth revolves across the sun.

Que 3. The orbit of Venus lies among which ones,
a) Mercury and Earth
b) Earth and Mars
c) Mars and Saturn
d) Mars and Jupiter

Answer: Mercury and Earth
Explanation:
The orbit of Venus lies between Mercury and Earth.

Que 4. When a particle in movement is acted upon with the aid of using pressure in a path perpendicular to the path of movement, the route accompanied with the aid of using the particle may be
a) A direct line
b) An ellipse
c) A circle
d) A parabola

Answer: A parabola
Explanation:
When a particle in movement is acted upon with the aid of using pressure in a path perpendicular to the path of movement, the route accompanied with the aid of using the particle may be a parabola.

Que 5. In connection with Kepler’s Law of planetary movement, recall the subsequent statements :
1. The Earth now no longer circulate alongside its orbit at a consistent rate.
2. The Earth’s movements are quickest at perihelion and slowest at aphelion.
3. All the planets revolve across the solar in elliptical orbits.

Which of the statements given above is/are correct?
a) 1 and 2 pair only.
b) 2 Only.
c) 3 Only.
d) 1, 2, and 3.

Answer: 1, 2, and 3.
Explanation: 

Kepler’s Law of planetary movement states that consistent with Kepler, all of the planets circulate in elliptical orbits across the solar at one of the focal points. Hence, declaration three is correct.
The factor at which the planet is near the solar is called perihelion, and the factor at which the planet is farther than the solar is called aphelion. The areal pace of a planet revolving across the solar in an elliptical orbit stays consistent. Hence, declaration 1 is correct. The Earth’s movements are quickest at perihelion as greater kinetic strength is close to it and slowest at aphelion as much less kinetic strength is close to it. Hence, statement 2 is correct.

Que 6. An equinox occurs when the sun is vertically above ____________.
a) Tropic of Capricorn.
b) Tropic of cancer.
c) Poles
d) Equator

Answer: Equator
Explanation: 
They occur when the sun is vertically above the Equator.

Que 7. What causes the changes in seasons?
a) Earth’s rotation and revolution 
b) Earth’s revolution
c) Earth’s revolution and inclination of its axis
d) Earth’s rotation and inclination of its axis

Answer: Earth’s revolution and inclination of its axis
Explanation:

Earth’s revolution and inclination of its axis change the season.

Que 8. The Earth is closest to the solar around _____________ each year.
a) May 3
b) July 3
c) January 3
d) March 3

Answer: January 3
Explanation: 
The Earth is closest to the solar around three January each year. The distance is 147.five Million km.

Que 9. Direct rays of the solar “fall at the equator on”:
a) 21 March
b) 21 June
c) 21 December
d) 21 September

Answer: 21 March
Explanation:

Direct rays of the solar fall at the equator on 21 March. 

Que 10. What is the precise time taken by the earth for one rotation with respect to the sun?
a) 24 hr.
b) 24 hr 30 min
c) 23 hr 56 min 4.09 sec
d) 24 hr 5 min 5-02 sec

Answer: 23 hr 56 min 4.09 sec
Explanation:

 23 hr 56 min 4.09 sec is the correct answer for the time taken by the earth for one rotation with respect to the sun.

Que 11. The axis of the earth is an imaginary line that makes an angle of  ___________ with its orbital surface.
a) 23.1/2˚
b) 66.1/2˚
c) 23
d) 67.1/2˚

Answer: 66.1/2˚
Explanation:

 The axis of the earth is an imaginary line that makes an angle of 66. 1/2˚ with its orbital surface. 

Que 12. The cycle of the seasons is caused due to 
a) Rotation
b) Revolution
c) Gravitation
d) Eccentricity

Answer: Revolution
Explanation:

 The cycle of the seasons is caused due to revolution.

a) Venus
b) The moon
c) The Pole Star
d) The Saturn

Answer: The Pole Star
Explanation:

 The earth while rotating around the sun, always keeps its axis pointed towards the pole star.

Que 14. The circle that divides the globe into day and night is called
a) circle of darkness
b) circle of day and night
c) circle of illumination
d) none of these

Answer: circle of illumination
Explanation:

The circle that divides the globe into day and night is called the circle of illumination.
