Q 2) 23 degrees and closer to the poles the seasonal effects are exaggerated.

Today the earth is tilted 23.5 degrees from the plane of the orbit around the sun but this tilt changes.During a cycle of about 40000 years the tilt axis varies between 22.1 and 24.5 degrees.As the axial tilt increases the seasonal contrast also increases so the winters are colder and summers are warmer.
