Answer: TRUE.
Explanation: "Glory" is an optical phenomenon caused by water droplets, consisting of concentric rings and somewhat similar to a rainbow.
The glory consists of one or more concentric, successively dimmer rings, each of which is red on the outside and bluish towards the centre.
In order to see a glory, therefore, the clouds or fog causing it must be located below the observer, in a straight line with the Sun/Moon and the observer's eye.
Colored rings appearing surrounding the shadow of an aircraft flying above a cloud is sometimes called The Glory of the Pilot.

Answer:
bulk density = 1400 kg/m³
bulk density after compaction = 1750 kg/m³
Explanation:
given data
volume = 0.5 m³
porosity = 40%
oven-dry weight = 700 kg
reduce the total porosity = 20%
to find out
bulk density and bulk density after compaction
solution
we know bulk density formula that is
bulk density = ...............................1
put here value we get
bulk density =
bulk density = 1400 kg/m³
and
if porosity decrease 20 % that mean volume change
so total volume = 0.5
total volume = 0.4 m³
so bulk density after compaction is from equation 1
bulk density =
bulk density after compaction = 1750 kg/m³
