What is the green flash at sunset over the ocean caused by?
The reason for a green flash lies in refraction of light (as in a prism) in the atmosphere: light moves more slowly in the lower, denser air than in the thinner air above, so sunlight rays follow paths that curve slightly, in the same direction as the curvature of the Earth. Higher frequency light (green/blue) curves more than lower frequency light (red/orange), so green/blue rays from the upper limb of the setting sun remain visible after the red rays are obstructed by the curvature of the earth. Green flashes are enhanced by atmospheric inversions, which increase the density gradient in the atmosphere, and therefore increase refraction. A green flash is more likely to be seen in clear air, when more of the light from the setting sun reaches the observer without being scattered. We might expect to see a blue flash, but the blue is preferentially scattered out of our line of sight and remaining light ends up looking green.
Why does sand on a beach cool down at night more quickly than the water?
I think what you are trying to say is the sand on a beach cools down easier at more quickly then the ocean water because of convection status, this makes the cool water much more cool then in the ocean water because of radiation.
What force makes cold water sink toward the ocean floor?
gravity
What happens to the old ocean floor as the sea floor spreads?
As the sea floor spreads, the old ocean floor gets pushed out, which makes the plates move.
How do you make ours a green planet?
Well, from space, it is a blue planet because about 4/7 of the surface is ocean.
Why does the ocean glow blue at night?
The bioluminescent organisms in the ocean, such as certain types of algae and plankton, emit light through a chemical reaction called bioluminescence. When disturbed, these organisms produce a blue-green light, causing the ocean to glow blue at night.
What do green sea tutles feed on?
green sea turtles eat green algae a tiny plant that grows in the ocean. that makes them green
Why is the ocean fluorescent at night?
it is the reflection of the moon light on the water i think.
Explain your observation in nature your reason for the absence of no green plants in the depth of the ocean where it is always dark?
The absence of green plants in the deep ocean can be attributed to the lack of sunlight needed for photosynthesis. Green plants require sunlight to produce energy through photosynthesis, and without this light, they cannot survive. In the deep ocean where light does not penetrate, other organisms such as deep-sea bacteria and chemosynthetic organisms rely on alternative energy sources such as chemical reactions to sustain themselves.
What will hapen if there is no moon?
We would have barely any light in the night and there would be no more tides in the ocean
Green plants are unable to live deep in the ocean because?
light energy is not strong enough! <--NovaNet
How do the presence and amount of phytoplankton affect the shade of blue of the ocean?
Phytoplankton absorb red and blue light, but reflect green light. Therefore, the presence and amount of phytoplankton can indicate the health of the ocean.
What makes the ocean light up at night?
dinoflagellates. They are a species of algae found in marine and freshwater. They are photosynthetic so they are considered ancestors to modern day plants Dinoflagelates contain bioluminescence which are responsible the ocean lighting up at night. They respond to touch so waves, people, or the wind can cause then to 'light up'. This is the same class of algae that is responsible for red tides and paralytic shellfish poisoning.
How does the ocean provide the Earth with the majority of its oxygen?
The ocean makes the sun and the air hit the water and then all the carbon dioxide is released and then oxygen is made.
Why are lighthouss important?
Because if you are out in the ocean, and the moon isn't out there its really dark. Same with if clouds coviring the sky it's fairly dark out in the ocean, and boat wrecks out there sometimes cause there was no light. So they put light houses up so that if it was a dark night there would be a light house to help see at night .
Why green plants are unable to live deep in the ocean because the?
Not enough light penetrates to allow photosynthesis.
Why does the sea sometimes look green?
The presence of algae often makes the sea green. So if you're looking at a part of the ocean that seems green, there might be a kelp forest underneath.
