Understanding the Color of the Sky and Sea

The video explains why the sky appears blue due to the scattering of sunlight by atmospheric molecules, which causes blue light to scatter more than other colors. It also describes why the sky turns red during sunset, as the sun's rays travel a longer path through the atmosphere, scattering shorter wavelengths and leaving red hues. The sea appears blue because water absorbs colors at different rates, with red absorbed first and blue last. Variations in sea color, such as green, red, or brown, are due to organic matter and plankton. A historical note mentions the use of 'Gök' for blue in ancient Turkish texts.

What causes the sky to appear blue?

• The absorption of red light

• The presence of blue gases in the atmosphere

• The reflection of the ocean

• The scattering of sunlight by atmospheric molecules

How does the color blue affect human psychology?

• It makes people feel hungry

• It increases anxiety

• It has a calming and relaxing effect

• It makes people feel energetic

Why does the sky turn red during sunset?

• The reflection of the sun on the ocean

• The presence of red gases in the atmosphere

• The sun's rays travel a longer path through the atmosphere, scattering more blue light and leaving red light

• The sun is closer to the Earth

What happens to sunlight as it enters the water?

• It disappears

• It changes direction and slows down

• It speeds up

• It remains unchanged

Which color of light is absorbed first in water?

• Red

• Green

• Yellow

• Blue

Why does the sea appear blue at greater depths?

• The scattering of blue light by water molecules

• The presence of blue algae

• The reflection of the sky

• Blue light is absorbed the least and penetrates deeper

What causes the sea to appear green?

• The reflection of green plants

• The combination of blue water and yellow pigments from organic materials

• The presence of green algae

• The scattering of green light by water molecules

Why might the sea appear brown?

• The presence of brown algae

• The presence of mud and silt

• The reflection of the sky

• The absorption of all colors except brown

What can cause the sea to appear red?

• The scattering of red light by water molecules

• The reflection of the sunset

• A bloom of red plankton

• The presence of red algae

In ancient Turkish literature, what did the word 'Gök' mean?

• Sky

• Blue

• Ocean

• Sunset
