Motions of the Earth
These are the two main motions of Earth.
rotation and revolution
the orbit of the earth around the sun is _________ shaped.
elliptical/ ellipse
What is the angle of the Earth's axis with its orbital plane?
66 1/2
This has hardly any atmosphere
Which means that there is no rain
Its a thing that orbits round the Earth
Which we can see wax and wane
The moon!
When do the sun rays fall directly on the Tropic of Capricorn?
22nd December (Winter Solistice)
What distinguishes day and night from space?
The circle of illumination
''The Earth is tilted'' Explain this statement.
The planet's axis of rotation is tilted at an angle of 23.5 degrees from the vertical plane and 66.5 degree from the horizontal plane.
Round and round the top shall spin, and if it stops the world will end. What am I?
Rotation of the Earth on it's axis
It takes 24 hours for the Earth to complete one rotation on its axis. What is this period of rotation called?
Earthday
A: The rotation of the earth is responsible for the day and night.
R: The revolution of the earth around the sun is responsible for the different seasons on the Earth.
(a) Both A and R are true and R is the correct reason.
(b) Both A and R are true but R is not the correct reason for A.
(c) A is true and R is false
(d) R is true and A is false
b
What is the cause of the change in seasons on Earth.
The revolution of the Earth around the sun and the tilt of the axis. The earth's spin axis is tilted with respect to its orbital plane. This is what causes the seasons.
What is always traveling, has life, has sense but doesn't live?
The Earth
Explain why the Sourthern hemisphere celebrated Christmas in summer.
On 22nd December the Tropic of Capricorn receives direct sun rays due to the tilt of the South pole towards it. As the sourthern hemisphere receives direct sunlight at this time it is summer there and they celebrate Christmas (25th December) on summers.
A: The equinox takes place on two days in a year.
R: The length of day and night are equal during the equinox.
(a) Both A and R are true and R is the correct reason.
(b) Both A and R are true but R is not the correct reason for A.
(c) A is true and R is false
(d) R is true and A is false
Why does the sun appear to rise in the east and set in the west?
The Earth rotates from West to East. So, when observed from the Earth, the Sun always appears to be rising on the eastern horizon and setting on the western horizon
