On the inside of a meander
Where does a meandering stream deposit most of its sediment?
Between 10 S and 10 N, caused by intense heating at equator.

Lower relative humidity
Without adding or removing any water vapor, a sample of air experiencing an increase in temperature, what happens to the relative humidity?
Land breeze forms
during the night the air over land is cooler and develops a high pressure in relation to the low over the water, air moves from H to L over water.
Dew point
