At night, when that part of Earth is facing away from the Sun, space looks black because there is no nearby bright source of light, like the Sun, to be scattered. If you were on the Moon, which has no atmosphere, the sky would be black both night and day.
It depends on what exactly you mean by visible, but if you can see the sun (which you can from outer space) then that means it's light is visible. ... In space, or on any planet or moon that doesn't have an atmosphere, there's nothing for the sunlight to bounce off of so the sky is always black.
During sunrise and sunset, the rays have to travel a larger part of the atmosphere because they are very close to the horizon. Therefore, light other than red is mostly scattered away. Most of the red light, which is the least scattered, enters our eyes. Hence, the sun and the sky appear red.
The Sun appears larger at sunrise than it does while higher in the sky, in a manner similar to the moon illusion. The Sun appears to rise above the horizon and circle the Earth, but it is actually the Earth that is rotating, with the Sun remaining fixed.
If the earth was flat, the water would form a giant utopia mountain in the center of the planet. A spinning disk gravity would pull towards the middle, meaning that every house would be built a slight angle the further into the center you travel. It would be almost like walking up a 90-degree angle the closer to the center of the earth you'd get (if the earth was flat).
Helium floats because it is buoyant; its molecules are lighter than the nitrogen and oxygen molecules of our atmosphere and so they rise above it. In the car, it's the air molecules that are actually getting pulled and pushed around by gravity as the result of the accelerating frame.
A clear cloudless day-time sky is blue because molecules in the air scatter blue light from the sun more than they scatter red light. When we look towards the sun at sunset, we see red and orange colours because the blue light has been scattered out and away from the line of sight.
Blue light is scattered in all directions by the tiny molecules of air in Earth's atmosphere. Blue is scattered more than other colors because it travels as shorter, smaller waves. This is why we see a blue sky most of the time. ... Also, the surface of Earth has reflected and scattered the light.
The moon has no atmosphere which is why if you were on the moon looking at Earth the sky would be black.
A satellite is much smaller than the moon. It would be almost impossible to see them with the naked eye. You'd need a telescope to see a satellite passby and even then you'd have to have a high resolution telescope to see it because it's just that small compared to the moon. It's like saying you want to see someone standing on the moon from earth with your naked eye.
The Earth has a radius of approximately 3965 miles. Using the Pythagorean theorem, that calculates to an average curvature of 7.98 inches per mile or approximately 8 inches per mile (squared). Which means the curvature is a subtle one not a dramatic one. Secondly, the buildings on a flat earth would have to be built at a angle the closer to the center you'd get because it would be like walking up a 90-degree hill the closer to the center you'd get.
Because the equator is closer to the sun. ... Because the sun's rays hit the earth's surface at a higher angle at the equator. e. Because the sun is always directly overhead at the equator.
The tilt of the Earth's AXIS is the most important reason why seasons occur. The Earth's axis is tilted at an angle of 23.5 degrees. This means that the Earth is always "pointing" to one side as it goes around the Sun. So, sometimes the Sun is in the direction that the Earth is pointing, but not at other times.
If the Earth weren't tilted on its axis, there would be no seasons. And humanity would suffer. When a Mars-size object collided with Earth 4.5 billion years ago, it knocked off a chunk that would become the moon. It also tilted Earth sideways a bit, so that our planet now orbits the sun on a slant.
The spinning and orbital speeds of Earth stay the same so we do not feel any acceleration or deceleration. You can only feel motion if your speed changes. For example, if you are in a car which is moving at a constant speed on a smooth surface, you will not feel much motion.
If you fly in the opposite direction that earth is spinning, basically flying against the spin, the earth is moving toward you with the spin at the speed of 1000 miles per hour. ... In order to fly east, the plane increases its speed relative to the surface of the Earth and begins to overtake it.
