How far can the eye see on the horizon of the ocean before the curve of the earth starts to bend?
As long as there is light and that light can reach back to your eyes, you can see even beyond the earth. Take for example, you can see the closest star (Proxima Centauri which 4.3 light years away; a light year = 10 trillion kilometers (or more exactly, 9.5 x 1012 km)) on Earth while the diameter of the Earth is only 12,756.32 kilometers. -peace on Earth V^_^V
What else can I help you with?
Which came first, plants or animals, in the evolution of life on Earth?
Plants came first in the evolution of life on Earth, appearing before animals.
Before photosynthesis evolved was oxygen rare in Earth's atmosphere?
Yes, before photosynthesis evolved, oxygen was rare in Earth's atmosphere. Early Earth's atmosphere was composed mainly of carbon dioxide, nitrogen, and water vapor. As photosynthesis evolved and became more widespread, oxygen began to accumulate in the atmosphere, leading to the oxygen-rich environment we have today.
What is Furthest point on the horizon the human eye can see?
How far can we see across the water to the horizon?Let r = the Earth's radius = 3963 milesLet h = height of a person in milesLet d = distance seen to the horizon in milesThe sight line of a person to the horizon would be on a line passing through their eyes and tangent to the Earth at the seen horizon.Since the radius of any circle is perpendicular to the tangent, the tangent and the radius make the legs of a right triangle. The radius plus the person's height (in miles) are the hypotenuse. We can then use the Pythagorean Theorem. Be careful to convert the person's height into miles.c2 = a2 + b2thus ( r + h )2 = d2 + r2then d2 = ( r + h )2 - r2d = sqrt ( ( r + h )2 - r2 ) )Examples: A person with eyes 6 feet off the surface would see approximately 3 miles. From the Bank of China building (1033 ft tall) you would see approximately 39.4 miles.Remember that mathematics is an approximate representation of the world around us. These numbers must be taken in that light. For instance, these numbers does not take into account atmospheric interference. We are also making the assumption that the Earth is a uniform sphere with a uniform radius of 3963 miles.
The energy used by all living things starts with?
The energy used by all living things starts with the sun. Through a process called photosynthesis, plants capture sunlight and convert it into chemical energy that is then passed through the food chain as organisms consume each other. This process is the foundation of all life on Earth.
Why did prokaryotes evolve before eukaryotes?
Prokaryotes evolved before eukaryotes because they are simpler in structure and function, making them better suited for surviving in early Earth's harsh conditions. Their ability to adapt quickly to changing environments allowed them to thrive and evolve first.
What does the moons horizon look like?
bananalike shape. Because the Moon is much smaller than Earth, the curve of the horizon is more obvious.
Is the horizon straight?
Well, the horizon is just where the sky and earth APPEAR to meet. So it's kinda your decision... :)
Why does horizon move away if you go closer to it?
The horizon appears to move away as you approach it due to the curvature of the Earth. As you get closer to the horizon, you are able to see farther around the curve of the Earth, causing it to appear as though it is moving further away. This effect is more noticeable in flat, open landscapes.
What causes the optical illusion of a curved horizon when looking out at sea?
The optical illusion of a curved horizon when looking out at sea is caused by the Earth's curvature. As you look further away, the horizon appears to curve due to the Earth's round shape, even though it may seem flat at close distances.
What places on earth is polaris seen on the horizon?
Where on Earth are you if Polaris is on your horizon?
Can you see the earth curving at the horizon e.g. when you look out to sea Or is the curve you see an optical illusion?
When looking at the horizon from a typical viewpoint, such as the beach, the curvature of the Earth is generally not perceptible due to the vastness of the landscape and the limited field of vision. The Earth is very large relative to a person's height, making the curve subtle and often indistinguishable. While the horizon is technically curved, the visual perception can be influenced by atmospheric conditions and perspective, leading to the impression that it is flat. Therefore, while the Earth is indeed curved, the curvature seen at sea level can often be more of an optical illusion than a clear visual indication of the Earth's shape.
Where can I go to see the curve of the earth?
You need to get to a sufficiently high altitude or distance from the Earth to being to see the curvature. A minimum heihgt of around 60 to 70,000 ft is required to be able the see the curvature of the horizon.
What is a place where earth and sky seem to meet called?
A horizon and one can be seen from every point on Earth.
Why can you see the sky from the North Pole to the Equator yet only a few miles of sea to the horizon - I don't get this?
The Earth gets in your way. The surface is curved and you can not see over the curve.
What is the importance of the horizon?
The horizon is point at which the earth curves away from our line of sight at the earth's surface.
Why do you have horizon?
Because the earth is a sphere. The horizon is the curvature of the earth (or other planet) as it falls away from you.
What is the line in the sky from horizon to horizon?
If you're talking about sky as in sky on this planet, then your answer would be the horizon (the point were the ground meets the sky from any vantage point on the surface). Or you could be talking about the atmosphere, which is the boundary between the earth and space and keeps life alive, and air on earth.
