What is the relationship between apparent solar time and mean solar time?
The Earth "day" of exactly 24 hours is the "mean solar day""Mean" is basically a scientific way of saying "average". It's called a "solar day " because it's based on the position of the Sun in the sky.There are natural variations in the length of the solar day because of the Earth's elliptical orbit and axial tilt.The "mean solar day" averages out the variations that happen during the year.This makes things much more convenient for everyday life."Mean solar time" is based on the "mean solar day".The "apparent solar day" is the what we actually observe, and its length varies from day to day.A sundial measures "apparent solar time". We can convert this time to mean solar time by using something called "the equation of time".Actually, the sundial shows "local apparent solar time".That's because the time shown by a sundial depends on its exact longitude.For convenience, mean solar time has time zones (based on longitude).So, longitude also affects the relationship between these twomeasures of time.
Explain earth 's position in the solar system and describe its neighbors?
explain earth's position in the solar system and describe its closest neighbors.
What planets have a rocky surface?
In this solar system there are four, Mercury, Venus, Earth, and Mars.
What is the brightess planet?
Viewed from Earth, Venus is the brightest planet.
What is the only planet in your solar system that man has walked on?
Earth
What could have significantly affected climatic variations and advances and retreats of ice sheets during the Pleistocene epoch?
There are a number of potential causes including Milankovitch cycles which are variations in the orbital eccentricity, axial tilt and precession of the Earth as it orbits the sun. These are thought to have an impact on the climate of the Earth. Also factors such as variations in solar activity and variations in the Earth's albedo (the amount of solar radiation reflected back into space) are thought to play a part in fluctuations in climate. Please see the related links.
Does the sun have seasons?
I would say no. It's always summer on the surface of the sun. The sun does undergo an 11 year cycle of activity known as sun spots. Earth's seasons are the result of earth's axial tilt with respect to the sun. Summer begins (on earth) when the sun reaches its highest point of the day in the hemisphere you're in, and the same is true for the other planets in our solar system. It is also possible seasonal differences could result between aphelion and perihelion in planets with sufficiently eccentric orbits. There is nothing analogous to produce seasonal changes on the sun. Solar temperature variations cannot be considered "seasonal."
What causes Fluctuations of Solar energy over a given geographic area?
experiences fluctuations on a seasonal and daily basis.
What causes a shadow on the earth during a solar eclipse?
The Moon.
What causes convection currents to form in Earth's atmosphere?
Solar energy
Why does are solar system have a solar eclipse?
Because there comes a time when the moon blocks the sun while it is revolving around earth. this causes a solar eclipse.
The passage of the Moon into Earth's shadow causes a?
it a solar eclipse because a solar eclipsee goes around the world
What causes weather and climate?
Type your answer here... The changing pattern of land and the increase of carbon dioxide in the atmosphere due to the running of vehicles and deforestation results in the formation of weather and climate.
What occurs when the moon moves directly between the earth and sun and causes a shadow over part of the earth?
Solar Eclipse
What are some possibke causes for climatic changes in the past?
Some possible causes for climatic changes in the past include variations in solar radiation, changes in Earth's orbit and tilt (Milankovitch cycles), volcanic activity, greenhouse gas concentrations, and natural variations in ocean currents and circulation patterns. Human activities, such as deforestation and the burning of fossil fuels, are also contributing to ongoing climate change.
What causes the moon to turn dark during a solar eclipse?
The Moon gets into the Earth's shadow.
When the Moon passes directly between the Earth and the Sun it causes a lunar eclipse?
No. it is a solar eclipse.
