What are the 3 factors which affect air density?

atmospheric pressure, evaporation content, air temperature

How many tides occur during a mixed diurnal tidal cycle

area experiences 2 high tides and 2 low tides of different size

horizontal air movements caused by differences in atmospheric density

Define convection current

vertical movement of air where warm, less dense air rises & cooler air sink

What are the 2 causes of upwelling currents?

offshore winds & and area of low pressure

Multiple surface currents moving together result in ?

5 large circular gyres throughtout the globe

what are the correct 4 factors that affect tidal range

size body of water, shape of coastline, weather=on shore winds, tidal surge

How are tides created?

Gravitational pull on Earth, mostly by moon & to lesser extent then the sun

How many tides occur during a diurnal tidal cycle and do they happen on solar or lunar days?

area experiences 1 high and 1 low tide each day - lunar day
