...(148.) In order farther to explain the differences of the length of the solar day we will now consider the inclination of the earth's axis to the plane of its orbit. This inclination is an important cause of the differences in the length of the solar day. Were the...

...it saya about the seasons, child." " It says, sir, that the changes in the seasons are owing •M * to 'the inclination of the earth's axis to the plane..."No, — it's not as clear as it might be. — The declination — " "/reclination, sir, is what is printed here." "Ay, inclination. I do not see why...

...this relative nearness or distance of the sun ought naturally to produce. Such a cause is found in the inclination of the earth's axis to the plane of its orbit. The effect of this arrangement can be easily illustrated by an impromptu orrery. Let a card placed...

...where the celestial equator crosses the ecliptic, and the angle formed by these lines is always equal to the inclination of the earth's axis to the plane of its orbit. These points are formed every year about fifty seconds farther west of where they were the previous...

...production of a glacial epoch ; but since the publication of these views, certain facts as to the effect of the inclination of the earth's axis to the plane of its orbit have been pointed nut by Sir R. Ball in a book lately published by him, which tend to greatly strengthen...

...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,...

...we have seen four causes which co-operate to produce the seasons actually existing on our planet: 1. The inclination of the earth's axis to the plane of its orbit. 2. The annual movement of the earth around the sun. 3. While moving annually around the sun , the earth...

...translation around the sun, relative to the different degrees of eccentricity of the terrestrial ellipse. The inclination of the earth's axis to the plane of its orbit produces, moreover, divisions of climate, wheuce results the law of geographical distribution of living...

...rotates is inclined to the plane of his orbit at an angle of 61° 18'. This quantity is very neariy equal to the inclination of the earth's axis to the plane of its orbit, and as the seasons depend in a measure upon this inclination, those of Mars are probably somewhat like...
