| Why is it hotter in summer and cooler in winter here in Maine? | The sun in summer shines directly on us vs in winter the suns light is speadout more so its not beaming directly on us |
| If Earth’s axis were tilted LESS than it is now, how would that affect the seasons? | Less extreme seasons but also that means warmer winters cooler summers |
| If Earth’s axis were tilted MORE than it is now, how would that affect the seasons? | The seasons would be super extreme super cold winters super warm summers |
| Why is the sun dimmer and cooler in Winter? Why do some places have | The sun in summer shines directly on us vs in winter the suns light is speadout more so its not beaming directly on us |
