Drivers of any age must take a vision test with each renewal. In 2011, the legislature turned away a proposal to test older driversâ reflex and reaction times starting at age 75, and to require every-six-months renewals for people 90 and older.
What causes the tides? It is the gravitational attraction of the sun and moon that cause waters of the ocean to raise and lower at different parts of the earth. Tides occur in oceans, and to a much smaller extent, tides also occur in large lakes, in the atmosphere, and within the solid crust of the earth.
The Moon pulls the waters in the oceans and seas towards it through gravity. As the Earth rotat â¦ es this bulge of water causes a high tide on the Earth roughly under the Moon. Less obvious, but true, is the fact that the Moon also causes a high tide on the side of Earth furthest from the Moon.
