Question

What would happen if the planet earth were not slightly tilted on its axis? Would it have any effect ?

Answer 1

The rays from the sun would hit the earth much more directly and the equator would kill you from heat and the poles from cold.

Answer 2

Being tilted on it's axis causes the earth to go through the various seasons.  Without the tilt, it would be summer at the equator all year long, and winter in the northern and southern hemisphere's all year.

Answer 3

Without the axial tilt, there would be no seasons on Earth.

Every day of the year would be just like every other day of the year (with very minor differences in temperature due to the Earth's elliptical orbit bringing the Earth a little closer to the sun in January and a little farther away in July).

Day and night would both be 12 hours all year long.

Its unlikely that life on Earth as it is today would survive.  But if the Earth had begun this way and life had evolved in that environment, things would be very different - no spring flowers (so no spring break), no fall leaves, no snow in winter (no snow days), no summer (no summer vacation).

Answer 4

There would be no seasons
