Why are temperatures more moderate around the fall and spring equinoxes? the angle at which earth's axis tilts changes. neither end of earth's axis is tilted toward the sun. the north end of earth's axis is tilted toward the sun. the earth briefly wobbles on its axis.

The answer is; Neither end of Earth's axis is tilted toward the Sun

The earth is tilted on its axis/orbital plane by 23.5 degrees. As the earth revolves around the sun, therefore, the sun position relative to positional latitude on the earth also changes.   Spring and fall equinoxes occur in March and September. In the months, the sun is overhead the equator and the length of days and night in north and south are more or less the same.  

Neither end of Earth’s axis is tilted toward the Sun.
