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 exist thanks to the gravitational pull of the moon and the sun, but vary depending on where the moon and sun are in relation to the ocean as the earth rotates on its axis. The moon and sunâs pull cause two bulges or high tides in the ocean on opposite sides of the earth.
