In general, the highest relative humidity is observed and the lowest relative humidity is observed

In general, the highest relative humidity is observed NEAR SUNRISE and the lowest relative humidity is observed during MID-AFTERNOON.

Relative humidity is inversely proportional to temperature. The colder the climate, the higher the relative humidity. The hotter the temperatures outside, the lower the relative humidity.

Relative humidity increases as the air temperature falls at night and peaks at dawn.  

Temperature peaks during mid-afternoon, thus relative humidity is at its lowest.

true. earthquakes are felt whenever there is a slip around a fault in the rocks below the earth. this reorientation of faults create sesmic waves and is known as earthquake, the severity of which is measured in richter scale. these are more prominent in hilly regions as the rocks usually form faults to balance the pressures on it.
