Tides & Seasons Notes Part 2

Tides Tide = daily rise & fall in ocean water level high and low tides occur twice daily high tides are caused by the gravitational pull of the moon & sun, causing the ocean water to “bulge” away from the Earth the moon has a greater impact because it is closer High tide occurs on the side facing the moon, but it also occurs on the opposite side. This is because the moon is also pulling the Earth away from the water on the other side.

Gravitational pull of the moon Low Tide Tidal bulge High Tide High Tide Gravitational pull of the moon Low Tide

moon and sun pull together = largest tides moon and sun pull against each other = weakest tides

The TILT is the reason for seasons! The Earth is tilted on its axis by 23.5.° As a result, the hemisphere that is tilted toward the sun receives more direct sunlight = more heat. causes longer daylight hours hotter temperatures = summer! The hemisphere tilted away from the sun experiences winter. The TILT is the reason for seasons!

For the Northern Hemisphere! = least daylight hours = most daylight hours = Equal hours of day and night
