Why does the sun appear to move visibly quicker at sunset and sunrise?

During the day, obviously the sun goes across the sky due to the earth’s rotation, but I don’t seem to be able to notice the movement when looking at it.

However at both sunrise and sunset when watching the shn I can visibly see the movement as it gets closer to or further from the horizon.

If the speed of the earth’s rotation is constant over the day, why does the sun appear to move more quickly at these times?

Because you have a fixed object (the horizon) as a reference point. When the sun is high in the sky, it’s hard to tell how fast it’s moving because there’s nothing around it. When it gets close to the horizon, it’s easy to see its motion compared to something else that’s not moving.
