List four safety measures one should take when there is a cyclone warning.

I'm gonna give you more than 4 So u can choose.

Turn off all electricity, gas and water.

Unplug all electrical appliances.

Keep your emergency kit close at hand.

If the building starts to collapse, protect yourself with mattresses, rugs.

Stay tuned to the radio for updates.

Stay inside until told it is safe to go outside.

as we know our atmosphere or air have different levels. every level has other gasses, and every gas has another permeability. when the light comes from lower permeability to higher permeability, it changes its direction. so that means that when the light comes from the moon to the earth, it changes it's direction many more times. it basically means that the shape of the light part of the moon is changed on the earth.
