...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...

...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...

...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...

...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,...

...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...

...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...

...To what only should the pronoun who refer? 10. Decline I, lady, lie. Geography. 1. What is caused by the inclination of the earth's axis to the plane of its orbit? 2. What Ts the width of the North Temperate Zone? 3. Namn in order, beginning at the north, the principal...

...of the wonderful results of what has been well called " the simple but stupendous contrivance " of the inclination of the earth's axis to the plane of its orbit ;— a contrivance, like the rest of God's works, full of wisdom and goodness, and well adapted to...

...dark in reference to the cause of the intense cold of the glacial time. It has been suggested that the inclination of the earth's axis to the plane of its orbit, which is 23° 28', and is the cause of our present seasons, may have been so different during the glacial...

...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...
