What else can I help you with?
Does the length of day light change every 7 days?
No. It changes every day.
What controls the length of a day?
The length of a day is primarily controlled by the rotation of the Earth on its axis. The Earth takes approximately 24 hours to complete one full rotation, which determines the length of a day. Variations in the Earth's rotation speed can result in minor changes in the length of a day.
When the seoson change some plants Respond to changes in what?
The length of day and night
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.
Which seasonal changes in day length least important?
The seasonal changes in day length that are least important typically occur in regions near the equator, where day lengths remain relatively consistent throughout the year. In these areas, the variation in daylight is minimal, making seasonal changes less impactful on daily life, agriculture, and wildlife behavior compared to regions farther from the equator. Additionally, the transition between seasons in these equatorial regions often does not significantly influence climate or ecosystems, as they experience a more stable environment year-round.
What happens to a 24 hour day on the equator?
The length of day & night are exactly 12 hours each. This never changes.
How will the length of day and night change if the sun increases in size?
If the sun increases in size but nothing else changes, then there will be no change in the lengths of day and night. However, the gravitational and tidal effects of changes in the sun's size is likely to affect the earth's rotational period and its orbit.
What is the response of plants or animals - to changes in the length of day or night - called?
This response is called, photoperiodism.
Why does the length of day light changes from day to day as it revolve around the sun?
due to elliptical shape of earth,the size of days and night are vary
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.
Birds migrate great distances each year and the primary cue for migration are changes in day length. These changes in day length in turn trigger changes in the birds. Behavior and body cha?
Birds migrate long distances primarily in response to changes in day length, which serve as a key environmental cue. As days grow longer in spring, hormonal changes initiate behaviors such as increased feeding and preparation for the journey. Additionally, physiological adaptations occur, including changes in fat storage and muscle development, enabling birds to endure the demands of migration. This remarkable synchronization with seasonal changes ensures their survival and successful reproduction.
How is the day length determined on Saturn?
From changes in its magnetic field, assuming that the magnetic field rotates with the core.
