Document Summary

The tilt of the earth"s axis causes sunlight to fall differently on earth at different times of year. Step 1 illustrates the tilt of earth"s axis, which remains pointed in the same direction in space throughout the year. As result, the orientation of the axis relative to the sun changes over the course of each orbit: northern hemisphere is tipped toward the sun in june and away from the sun in the. December and it is reverse is true for the southern hemisphere. Summer (june) solstices, which occurs around june 21 is the moment when the northern. Hemisphere is tipped directly toward the sun and receives the most direct sunlight. Winter (december) solstices, which occurs around december 21, is the moment when the northern. Spring (march) equinox, which occurs around march 21, is the moment when the northern. Hemisphere goes from being tipped slightly away from the sun to being tipped slightly toward the sun.
