In which layer of the Earth's atmosphere does the 'Darkness Before Dawn' phenomenon primarily occur?

• Troposphere

• Stratosphere

• Mesosphere

• Thermosphere

What role does the Earth's atmosphere play in the 'Darkness Before Dawn' phenomenon?

• It reflects sunlight, causing darkness

• It refracts sunlight, delaying dawn

• It absorbs sunlight, creating darkness

• It scatters sunlight, leading to dawn

How does the 'Darkness Before Dawn' phenomenon affect the biological rhythms of living organisms?

• It disrupts circadian rhythms

• It synchronizes biological clocks

• It has no effect on biological rhythms

• It accelerates metabolic processes

What is the relationship between 'Darkness Before Dawn' and the concept of twilight?

• Twilight occurs after dawn

• Twilight is the same as darkness before dawn

• Twilight is the period before darkness

• Twilight is the transition from darkness to dawn

Which experiment could be conducted to study the 'Darkness Before Dawn' phenomenon?
