* The Earth is tilted on its axis: This tilt is what causes seasons.
* Winter Solstice: This is the day when the Northern Hemisphere is tilted *furthest away* from the sun.
* So, is it tilted towards the sun? No, the Northern Hemisphere is tilted *away* from the sun during the winter solstice.
Think of it this way: Imagine a spinning top. The top is tilted, and as it spins, different parts of the top are closer or further away from the ground. The Earth is like the spinning top, and the sun is like the ground. During the winter solstice, the Northern Hemisphere is like that part of the spinning top furthest away from the ground (the sun).
Important Note: The Southern Hemisphere experiences summer during the Northern Hemisphere's winter solstice, and vice versa. This is because the Southern Hemisphere is tilted towards the sun at that time.
