...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,...

...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...

...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...

...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...

...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...

...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...

...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...

...extreme eccentricity of the orbit than when it is move nearly circular. The obliquity of the ecliptic, or the inclination of the earth's axis to the plane of its orbit, varies as has been said : at its maximum the polar regions would receive T^ more of heat than they...

...apsides.1 This line is not always directed to the same point in the heavens, but revolves ; and as the inclination of the earth's axis to the plane of its orbit may be considered fixed, the tendency of this movement is to bring about the seasons at all parts of...
