Question 17 a normal lapse rate of 3.5 °f/1000 ft is equivalent to o a.3.5 c/m. o b.4°c/1000 ft. c.3.5 °c/km. o d.6.5°c/1000 m.

d.6.5°C/1000 m

Explanation:

Given that normal lapse rate=3.5 °F/1000 ft

We know that the rate of change temperature of a parcel of air while moving downward or upward is know as normal lapse rate.

If the temperature is decreasing then the lapse rate will be positive ans vice versa.when temperature is not changing with the elevation then lapse rate will be zero.

The normal lapse rate is equal to 6.5°C/1000 m or 3.5 °F/1000 ft.
