Movements of Earth - 1 Class 5 Worksheet SST

Q1: True or False

(i) The Earth rotates on its axis.
Ans: True

The Earth spins on its own axis, completing one rotation every 24 hours, which causes day and night.

(ii) The Earth revolves around the Sun. 
Ans: True

The Earth orbits around the Sun in an elliptical path, completing one revolution in about 365.25 days.

(iii) The Earth's rotation causes day and night.
Ans:  True

As the Earth rotates, different parts of the planet face the Sun, causing day, while the opposite side experiences night.

(iv) The Earth's revolution causes the change in seasons.
Ans: True

The Earth's tilted axis and its orbit around the Sun lead to varying sunlight distribution, which causes the seasons.

(v) The Earth's axis is tilted at an angle of 45 degrees.
Ans: False

The Earth's axis is tilted at an angle of 23.5 degrees, not 45 degrees, relative to its orbit around the Sun.

(vi) The equator is an imaginary line that divides the Earth into two equal halves.
Ans: True

The equator divides the Earth into the Northern and Southern Hemispheres, marking the midpoint between the poles.

(vii) The Arctic Circle is located at the North Pole.
Ans: False

The Arctic Circle is located at 66.5 degrees north of the equator, while the North Pole is at 90 degrees north.

(viii) The Tropic of Capricorn is located at 23.5 degrees south of the equator. 
Ans: True

The Tropic of Capricorn marks the latitude where the Sun is directly overhead during the December solstice.

(ix) The summer solstice in the Northern Hemisphere occurs in June.
Ans: True

The summer solstice, when the Northern Hemisphere experiences the longest day of the year, happens around June 21.

(x) The International Date Line is located at 180 degrees longitude. 
Ans: True

The International Date Line is an imaginary line at 180 degrees longitude that marks the boundary between calendar days.

Q2: Match the Following

Ans: 

Q3: Fill in the Blanks

(i) The Earth takes approximately ________ hours to complete one full rotation on its axis.
Ans: 24

(ii) The Earth's ________ is tilted, causing the change in seasons.
Ans: Axis

(iii) The imaginary line that divides the Earth into Eastern and Western Hemispheres is called the ________.
Ans: Prime Meridian

(iv) The ________ is the longest day of the year in the Northern Hemisphere.
Ans: Summer solstice

(v) The ________ is the shortest day of the year in the Northern Hemisphere.
Ans: Winter solstice

Q4: Short Answer Questions

(i) Explain the difference between the rotation and revolution of the Earth.
Ans: The Earth rotates on its axis, taking 24 hours, which gives us day and night. It revolves around the Sun in 365.25 days, causing the seasons.

(ii) How does the Earth's tilt affect the seasons?
Ans: The Earth's tilt makes different parts receive more or less sunlight. When the Northern Hemisphere is tilted towards the Sun, it has summer, and when tilted away, it has winter.

(iii) Name and describe the two solstices.
Ans: The summer solstice is the longest day (June 21), and the winter solstice is the shortest day (December 21).

(iv) What is the significance of the International Date Line?
Ans: The International Date Line is where the date changes when crossing it. If you go east, you add a day, and if you go west, you subtract a day.
