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.
Ocean tides are caused by the gravitational interaction between the Earth and the Moon. There are two high tides and two low tides each day. During New Moon and Full Moon the difference between high and low tides is more extreme. Those are called spring tides. During First Quarter and Last Quarter phases of the Moon the difference between high and low tides is less extreme. Those are called neap tides.
