  • helpful verrrrry helpful with my science homework!!!

  • whats the speed????????

  • i can't tell a thing!!!!!!!

    

  • ok somone help me, Fast please. I need to answer "How does the Earth's Titlt affect temperature" Please help within the hour or two or else it'll be no use. Thanks if you answer! :D

  • @SubscribeToTyler too bad its been a month man

  • @SubscribeToTyler i meannnnn i dont know shit about astronomy and even I can gather that the TILT of the earth directly effects the amount of sunlight its receiving in certain areas there for the amount of heat.

  • @888chupacabra well thanks for giving me some knowledge for the future but i already did the project lol. Thanks anyways :D

  • THIS is a good why the seasons happen video, it's got all the inbetween time.

  • My head is spining

  • A very bad video demonstration.  Although not intended, this animation makes it look like the earth changes its tilt, which it does not. Half-baked demonstrations like this confuse more than clarify.

  • With reference to the Sun it does! There is also a slight wobble in the tilt which occurs over 1,000s of years cycle.

  • Well the tilt doesn't change persay. It always is pointed to the north star.

  • So the tilt changes as it rotates around the sun? Meaning it's not always tilted to one side, it changes when it is half way around.

  • It sure does... the tilt is what effects our seasons. Relative to the sun the tilt changes one full cycle per year, but relative to the orbital plane it remains constant. to to say the tilt changes is not entirely true, it's the angle relative to the sun that changes, and that heats the earth unevenly causing the seasons to change.

  • The tilt itself remains fixed* - although at different positions in the orbit around the sun the tilt causes the northern and southern hemispheres to alternate between leaning towards or away from the Sun depending on its position in orbit.

  • Imagine leaning into a headstrong wind as you're walking along a pavement and you're about to overtake another (slower) pedestrian: as you approach (from behind) your head is nearer to that person than your feet - as you draw level, your head & feet are the same distance from the person you're overtaking (even though you are leaning in the direction that you are walking) - as you pass the other pedestrian you are now leaning away from them so that your head is further away than your feet.

  • Now imagine this with two spheres - one has a slight tilt (in one direction) and is constantly overtaking the other sphere by moving around it. The orbiting sphere is itself also rotating to produce night & day on the earth. The different postions in its orbit give rise to the seasons by virtue of its tilt.

  • thanks for helping me to understand how solstices and equinoxes happen

    btw - the summer solstice is just one week away! =D how are you planning to celebrate it?
