A series of colored rings may appear surrounding the shadow of an aircraft flying above a cloud with tiny water droplets. Those rings are called the "glory."
True/False

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.

heat from the core of the earth causes convection currents to occur in the mantle. these currents slowly move the crust around.
