10. Read and translate. Explain the origin of tides to your classmates:
Tides (приливы и отливы) are periodic rise and fall of land and water on the earth. Tidal motions are primarily exhibited by water: the motion of land is barely detectable. As the earth-moon system rotates about its centre of gravity, which is within the earth, the earth bulges in the direction of the moon and in the exactly opposite direction, owing to the resultant of the moon’s gravitational attraction and the centrifugal forces resulting from the system’s revolution.
The sun produces similar, though smaller tidal effect. Exceptionally high high tides (полноводные приливы) occur at full and new moon; exceptionally low high tides (отливы) at first and third quarter. The friction of tides causes the day to lengthen 0. 001 second per century.
