...The succession of the seasons is the result of the annual revolution of the earth round the sun, and of the inclination of the earth's axis to the plane of the ecliptic. The angle of inclination is about 23} degrees. It thus follows that the axis of the earth, though it...

...plants, are intimately associated with the succession of the seasons, and this in its turn depends on the inclination of the earth's axis to the plane of the ecliptic, and on the great primary laws by which this axis is constantly maintained in a position parallel to...

...perpendicular to the plane of its orbit is 23° 51', which in a similar way is somewhat greater than the inclination of the earth's axis to the plane of the ecliptic, which is 23° 27' 24". So that in both respects Mars offers a slight exaggeration of the conditions...

...antiquity; the first who measured a degree of the meridian, and the first who accurately determined the inclination of the earth's axis to the plane of the ecliptic. He flourished at Alexandria, and died nc 196, aged eighty. ERFURT, in Thuringia, belonging to Prussia,...

...of December? 3. Do these points belong to the orbit of the earth? From what do they result ? What is the inclination of the earth's axis to the plane of the ecliptic? Is the earth's axis always parallel to itself? During what portion of the year does the sun appear...

...through the earth's centre, and its intersection with the celestial sphere is called the ecliptic. The inclination of the earth's axis to the plane of the ecliptic gives rise to the change of seasons and the change in the relative length of day and night. TWILIGHT....
