Why does a sea breeze blow from the sea to the shore during the day but reverse itself at night?
As the land warms during the day, the air above it also warms, causing rising convection currents above the land. The cool air above the ocean flows in to replace the rising warm air. At night the land cools below the temperature of the sea. The warmer air above the sea rises (convection current), and the cooler air from the land flows in to replace it. This revers is caused by temperature fluctuations on land but very little temperature fluctuation in sea water.

What did Sir Isaac newton conclude a falling apple and the moon circling the earth have in common?
The earth’s gravity causes both events
Explain the difference between the magnetic pole and the geographic North Pole. (Use the North Star or Polaris in your explanation)
The geographic North Pole is on the axis of the earth about which the earth rotates and points at the North Star (Polaris). The magnetic pole is located in northern Canada (Hudson Bay).
