Movements of Earth - 2 Class 5 Worksheet SST

Q1: Fill in the Blanks

(ii) The spinning of the Earth on its axis is known as _______________.
Ans: Rotation

(iii) The Earth's axis is tilted at an angle of _______________ degrees.
Ans: 23.5

(iv) The movement of Earth's axis is responsible for the change in _______________.
Ans: Seasons

(v) The longest day of the year is during the _______________ solstice.
Ans: Summer

(vi) The shortest day of the year is during the _______________ solstice.
Ans: Winter

(vii) The equator receives almost _______________ hours of daylight throughout the year.
Ans: 12

(viii) The imaginary line that runs from the North Pole to the South Pole is called the _______________.
Ans: Prime Meridian

(ix) The Earth's rotation causes the phenomenon of _______________.
Ans: Day and night

(x) The movement of Earth around the sun causes the change in _______________.
Ans: Seasons

Q2: Multiple Choice Questions (MCQs)

(ii) Which season is experienced in the Northern Hemisphere when it's summer in the Southern Hemisphere?
(a) Spring
(b) Autumn
(c) Winter
(d) Summer
Ans: (d)
When it's summer in the Southern Hemisphere, it's winter in the Northern Hemisphere and vice versa. This is because of the tilt of the Earth's axis. When one hemisphere is tilted towards the sun, it experiences summer, while the other hemisphere is tilted away and experiences winter

(iii) The imaginary line that divides the Earth into Northern and Southern Hemispheres is called the ___________.
(a) Prime Meridian
(b) Equator
(c) Tropic of Cancer
(d) Tropic of Capricorn
Ans: (b)
The equator is the imaginary line that circles the Earth horizontally, dividing it into the Northern Hemisphere (north of the equator) and the Southern Hemisphere (south of the equator).

(iv) During which movement of Earth do we experience different lengths of daylight and darkness?
(a) Revolution
(b) Rotation
(c) Tilting
(d) Spinning
Ans: (a)
Different lengths of daylight and darkness are primarily caused by the Earth's revolution around the sun. As Earth orbits the sun, the tilt of its axis causes varying amounts of sunlight to reach different parts of the planet, resulting in the changing seasons.

(v) What causes the change of seasons on Earth?
(a) Changes in Earth's magnetic field
(b) Distance from the sun
(c) Tilt of Earth's axis
(d) Rotation of the moon
Ans: (c)
The changing seasons on Earth are primarily caused by the tilt of its axis. This tilt causes different parts of the Earth to receive varying amounts of sunlight throughout the year, leading to the four seasons (spring, summer, autumn, and winter). The Earth's revolution around the sun also plays a role in this phenomenon.

Q3: True and False

(ii) The equator receives the same amount of daylight throughout the year.
Ans: False

(iii) The movement of Earth around the sun is called rotation.
Ans: False

(iv) The Arctic Circle experiences 24 hours of darkness during the winter solstice.
Ans: True

(v) Day and night are caused by the Earth's revolution around the moon.
Ans: False

Q4: Match the Following

Q5: Short Answer Questions

(ii) What is an equinox? Describe what happens during an equinox.
Ans: An equinox is when day and night are approximately equal in length. During an equinox, the sun is directly over the equator, causing nearly equal amounts of sunlight to fall on both the Northern and Southern Hemispheres.

(iii) How does the tilt of Earth's axis cause the change in day length during different seasons?
Ans: The tilt of Earth's axis causes the angle at which sunlight hits the Earth's surface to change throughout the year. This changing angle leads to varying day lengths as different parts of the Earth receive varying amounts of sunlight during its orbit around the sun.

(iv) What is the significance of the Tropic of Cancer and the Tropic of Capricorn?
Ans: The Tropic of Cancer and the Tropic of Capricorn are significant because they mark the points where the sun is directly overhead during the solstices. The Tropic of Cancer marks the northernmost point where the sun is directly overhead, and the Tropic of Capricorn marks the southernmost point.

(v) Describe the differences between the summer solstice and the winter solstice.
Ans: The summer solstice is the longest day of the year when the sun is directly over the Tropic of Cancer, resulting in the highest amount of daylight in the Northern Hemisphere. The winter solstice is the shortest day of the year when the sun is directly over the Tropic of Capricorn, resulting in the shortest amount of daylight in the Northern Hemisphere.
