Answer:
1) Axis is defined to be an imaginary line that remains constant in the rotating body, and the rotating body actually rotates keeping that axis constant. Whereas, orbit is defined as an imaginary line or path on which somebody revolves in some circular or elliptical path keeping somebody in either of its foci.
2) Rotation" refers to an object's spinning motion about its own axis. "Revolution" refers the object's orbital motion around another object. For example, Earth rotates on its own axis, producing the 24-hour day. Earth revolves about the Sun, producing the 365-day year
E
1) shape of the earth is a sphere. example ball Cricket ball etc.
2) We get day and night because the Earth spins (or rotates) on an imaginary line called its axis and different parts of the planet are facing towards the Sun or away from it. ... Over a year, the length of the daytime in the part of the Earth where you live changes. Days are longer in the summer and shorter in the winter.
3) Revolution of Earth
Earth revolves in orbit around the sun in 365 days, 6 hours, 9 minutes with reference to the stars, at a speed ranging from 29.29 to 30.29 km/s. The 6 hours, 9 minutes adds up to about an extra day every fourth year, which is designated a leap year, with the extra day added as February 29th.
Answer:
D.
Ans. 1 = The difference between axis and orbit is that the former is an invented line on which the planet or star does its rotation, whereas the latter is the invented path that is covered by the planet or star surrounding a central body. When our planet moves about its axis, the result is the alternate of nights and days and the time taken is 24 hours. The orbit of Earth is an elliptical pathway that surrounds Sun, the central star of the solar system. It takes Earth 365 days to complete one orbit around the Sun, and the result is a year. Earth’s movement about its axis is rotation, whereas its movement about the orbit is the revolution.
Ans 2. = when earth moves on its axis it is called rotation and when sun moves around the sun it is called revolution
E.
Ans 1. = Earth is a sphere or, more correctly, an oblate spheroid, which is a sphere that is a bit squished down at the poles and bulges a bit at the Equator. To be more technical, the minor axis (the diameter through the poles) is smaller than the major axis (the diameter through the Equator).
Ans 2. = The Earth orbits the sun once every 365 days and rotates about its axis once every 24 hours. Day and night are due to the Earth rotating on its axis, not its orbiting around the sun. The term 'one day' is determined by the time the Earth takes to rotate once on its axis and includes both day time and night time.
Ans 3. = Revolution is the movement of the Earth around the Sun. The Earth takes 24 hours to complete a rotation with respect to the sun. ... The path of the Earth moving around the Sun is called an orbit. The Earth's orbit is elliptical
