Question

10 imagine that the earths axis went straight up and down, instead of tilting. explain whether or not the earth would still have different seasons. support your answer with evidence from the text.

Explanation:

The Earth's seasons are caused by the tilt of its axis (about 23.5°) as it orbits the Sun. If the axis were vertical (no tilt), the angle at which sunlight hits different latitudes would remain relatively constant throughout the year. Regions near the equator would still get more direct sunlight, and polar regions less, but the variation in sunlight intensity and duration across the year (which drives seasonal changes like temperature and daylight hours) would be eliminated. For example, currently, the Northern Hemisphere tilts toward the Sun in summer (more direct sun, longer days) and away in winter (less direct sun, shorter days). With a vertical axis, every location would have the same sun angle and day - night length throughout the year, so seasons as we know them (distinct spring, summer, fall, winter with large temperature and daylight changes) would not exist.

Answer:

The Earth would not still have different seasons. The tilt of the Earth's axis is the main cause of seasons. With a vertical axis, the angle of sunlight and length of days/nights would not vary seasonally, so the temperature and daylight - related changes that define seasons would not occur.
