It's because the Earth's axis is tilted. If the axis were perpendicular to the orbit, daylight would last 12 hours every day, pretty well everywhere on Earth.
Because the Earth's axis is tilted the amount of daylight depends on the latitude. Try to visualize the Earth rotating around its axis; when the north pole points away from the Sun, the Sun is always below the horizon from the point of view of somebody at the north pole. For somebody at the south pole, the Sun will always be above the horizon (at that time of the year). For locations in between, the days get longer and longer as you move - in this example - from the north pole towards the south pole.
What else can I help you with?
How do you have longest day?
The change in the length of the day is due to the tilt of the Earth. You will have your longest day of the year when you live of the part of the Earth that is tilted towards the Sun.
What contains light-sensitive cells that changes length of days and nights?
Nothing can change the length of day and night except the normal seasonal progression.
Does the sun rise in the same location in the sky?
No, the sun rises in a slightly different location in the sky each day due to the Earth's tilt and orbit. This change in the sun's rising location is what causes the seasons to change throughout the year.
Can you find latitude using the length of day?
The length of day alone does not provide enough information to determine latitude. The length of day varies with latitude, but other factors such as time of year and location also influence it. To find latitude, you typically need additional information like the altitude of the sun at noon or the angle of the shadows cast by objects.
How does the Earths rotation affect shadow length of objects here on Earth?
The Earth's rotation causes shadows to change length and direction throughout the day. As the Earth rotates from west to east, the sun appears to move across the sky, resulting in shadows that shift in angle and length. In the morning and late afternoon, shadows are longer due to the sun's low angle, while at noon, when the sun is highest, shadows are shorter. This dynamic is influenced by both the time of day and the latitude of the location.
Is it true that at the equator day length does not change?
yes. All the way around the equator the day length doesn't change.
Every 7 days the length of daylight changes by several minutes?
Yes, the length of daylight changes gradually throughout the year due to the tilt of the Earth's axis as it orbits the sun. This change is most noticeable during the equinoxes when day and night are nearly equal in length. The speed and direction of change vary depending on the latitude of a location.
What location always has the same length of day?
Everywhere: the length of the day is always 24 hours irrespective of latitude & longitude since the angular rotation of the planet is 360º per 24hours. The DAYLIGHT length changes seasonally and proportionally to latitude, but the DAY length is constant.
Is summer solstice and longest day the same as they have different dates in my diary?
Yes, they're the same. The Summer Solstice happens at a precise moment in time; depending on your location, the "longest day" in your diary may actually be one day earlier or later. This would also depend on where your diary was published; if your diary was published in California but you live in India, your diary may a day off for your location. However, the change of day length from one day to the next at the solstices is measured in seconds, so it doesn't matter very much. At the equinoxes, the change in day length from one day to the next may be several minutes, depending on your latitude.
Does the length of day light change every 7 days?
No. It changes every day.
What causes rotation and revolution?
Length of the day, Direction of sunrise, and change from light and day.
If the entire population of world moved to antarctica would it affect th length of day if so how?
It would have zero effect.The length of a day is determined by one's location on the planet.
What is the day of length in June?
In June, the length of the day varies depending on your location. In general, the day is longer in the Northern Hemisphere due to the summer solstice, which falls around June 21st. In the Southern Hemisphere, the day is shorter during this time.
When the seoson change some plants Respond to changes in what?
The length of day and night
What factors would affect the length of the day?
The length of the day would change if either the rotational speed of the the planet or the orbital distance from the sun changed. However, if you mean what factors affect the length of daylight, then that is different.
Why does the change in the length of a solar day occur?
Because Ciaran Nicholls blocks out the sun
Does the length of day change in a week?
In terms of the amount of minutes of daylight, that changes every day, so it certainly does change in a week. Days still have 24 hours though, except when the hour goes forward and back.
