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.
Tides refer to the rise and fall of our oceansâ surfaces. It is caused by the attractive forces of the Moon and Sunâs gravitational fields as well as the centrifugal force due to the Earthâs spin. As the positions of these celestial bodies change, so do the surfacesâ heights.
