Let's look at the railway rails laid on plain. There the flat surface of the earth is stretched extensively so far as soon as the sight can reach. Everywhere round ourselves we see the sky in the distance converging with the earth and forming there a long straight line. This line is called as horizon.
The ideal example of horizon is a huge reservoir at which it is not visible coast. On the sea the horizon represents an equal and continuous line.
We can consider horizon as a continuous line. It is valid so though any object — a hand, the mountain, a building — can partially or cover its kind completely. And still the horizon remains on the place even if we will enter into the house and we will close behind themselves a door. If the object, a kind covering to us, becomes transparent, we will see horizon. It is represented on the following page below.
