Document Summary

Evaporate water from a warm ocean (ocean cools and air is warmed) Form a cluster of thunderstorms as air rises. Moisture condenses as the air rises (phase change. Heat is released and causes air to be less dense and air rises further. Winds flow from high pressure to low pressure so they increase. Cyclonic flow is due to the coriolis effect. Largest tide is the bay of fundy 15m during spring tide. Tides: periodic rises and fall of the ocean. Ocean tides > gravitational attraction of moon and sun. The earth rotates beneath the tidal bulges and. The centrifugal force of the spinning water keeps the bulge from collapsing. Spring tides: highest high tides and lowest low tides each cycle; sun and moon forces add up. Neap ides: lowest high tide and highest low tide; sun and moon pulling one another. Semi-diurnal tides: 2 high tides and 2 low tides/day. Diurnal tides: 1 high tide and 1 low tide/ day.
