The tilt of the earth directly relates to what seasons we experience. When the North Pole tilts toward the Sun, it's summer in the Northern Hemisphere. When the South Pole tilts toward the Sun, it's winter in the Northern Hemisphere.
Why do the northern and southern hemispheres have different seasons? One part of the planet is more directly exposed to the sun light.
How does the tilt of the earth relate to the different seasons? Only one hemisphere can be tilted towards the sun at any given point. When one hemisphere is tilted towards the sun, the other hemisphere is less sunlight. This means that one hemisphere will be in summer and the other will be in winter.
During the northern hemisphere summer is the north pole pointed toward or away from the sun? toward the sun
