...'what it says about the seasons, child." " It says, sir, that the changes in the seasons are owing to ' the inclination of the earth's axis to the plane of its orbit.' I do not exactly understand what that means, uncle." "No,—it's not as clear as it might be.—The...

...to describe these phenomena, it is necessary to consider, THE INCLINATION OF THE EARTH'S AXIS. 60. The inclination of the earth's axis to the plane of its orbit never varies, but always makes an angle with it of 23 1o, as it moves round the sun. The axis of the...

...rapidity. 232. The phenomena of the SEASONS, which we may now explain, depend on two causes ; first, the inclination of the earth's axis to the plane of its orbit ; and, secondly, to the circumstance that the earth's axis always remains parallel to itself. Imagine...

...satellites, the axis of rotation of the planet almost coincides with the plane of its orbit. As it is on the inclination of the Earth's axis to the plane of its orbit, therefore on the obliquity of the ecb'ptic (ie on the angle which the apparent path of the sun makes...

...grace; and was profound on this, the greatest concern of human life, while unable even to comprehend how the " inclination of the earth's axis to the plane of its orbit" could be the cause of the change of the seasons. And was it thus with her uncle? — he who was a pillar...

...orbit has an inclination towards changes,' you say." " The changes in the seasons, sir, are owing to 'the inclination of the earth's axis to the plane of its orbit.' It does not say that the orbit has an inclination in any particular way." Thus was it with Mary Pratt,...

...of the year from two causes ; 1. The inequality in the rate of the earth's motion round the sun ; 2. The inclination of the earth's axis to the plane of its orbit. The mean solar day, or common day, is the average length of the solar days throughout the year. It...

...be used. in connection with the globe. The Change of Seasons. The change of seasons is produced by the inclination of the earth's axis to the plane of its orbit, as shown by the inclination of the axis of the globe. Illustration. The change of the seasons may be...

...produced, which may here be done, an explanation of what is meant by the plane of the earth's orbit, and of the inclination of the earth's axis to the plane of its orbit as it revolves around the sun, will be necessary. This will be rendered comparatively easy, however,...

...a half, and others in twentythree hours. As to the vicissitudes of the seasons — this is owing to the inclination of the earth's axis to the plane of its orbit. If the axis of the earth stood perpendicular to the plane of its orbit, there would be no variety in...
