Two regions of air are colliding. The two regions have different temperatures and pressures, but within each region, the temperatures and pressures are
similar. These regions would be called:
A. pressure troughs.
B. cyclonic depressions.
c. tropical disturbances.
D. air masses.

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.

the climate of each region is different from one another.
