Assume you're talking to someone ignorant of the basic facts of astronomy. Those are completely different things. What are the main factors which determine the.
Similarly, how would you prove to them. As i asked before, separate. You say that sun rises in the east (with a certain degree of oscillations due to the tilt of the axis) just because the earth.
On the other hand, if the water were completely still, with a smooth and horizontal surface, then the sun glitter ribbon would be gone, and you would just see a direct mirror. 1) the sun seems brighter (more dazzling) if there is more scattering in the atmosphere. How long until the sun gets burned down to the point where it cannot sustain life on earth anymore? The sun does not rise, it is the horizon that goes down.
The sun will last, at its current brightness for 9 billion more years. The sun would actually look very small to us in the sky if there were no atmosphere (it's the same. It's consensus that the very similar apparent sizes of the moon and the sun as seen from earth is a coincidence (as already answered in this site). The core temperature of the sun is on the order of 15 million degrees kelvin while its surface temperature is around 6000k.
