Which is the best reason for why we have seasons in Anchorage? a. The Earth orbits the sun b. The Earth is tilted on its axis c. The Earth's atmosphere absorbs solar radiation d. The Earth rotates around the sun

a. The Earth orbits the sun

Explanation:

Anchorage is the largest city in the United state of Alaska.

The major reason why we have seasons anywhere on the earth is the orbiting of the sun around the earth. Since the orbit of the earth is elliptical around the sun so it sometimes comes near the sun and sometimes far away from the sun due to which the average temperature of the earth keep varying during the entire year in phases of the distance from the sun.

When the earth is closer to the sun then the average temperature of the earth is relatively warmer than the average temperature when the earth is farther from the sun.

Tilt of the earth's axis also complements this phenomenon of season change but without the revolution of the earth around the sun in its elliptical orbit that could not be possible.
