Earth is moving at about 18 miles per second, which is roughly 67,000 miles per hour. The metric equivalent is 107,218 km/hr. At the same time, it's spinning on it's axis (at the equator) at 1040 miles per hour (1674 km/hr)

Additional answer
The Sun doesn't produce a shadow. It's objects that are in the way of the sunlight that produce shadows.

∙ 11y ago"How fast ..." is always relative to something else.
-- From the point of view of an observer on the sun, the Earth circles around him
once a year at a distance of 93 million miles. That boils down to something like
67,000 miles per hour.
-- From the point of view of an observer on Earth, the numbers are exactly the same,
but it's the sun that's doing the orbiting.

∙ 12y agoLet's calculate that. First of all we know that in general, the time it takes to travel a distance is equal to the length of that distance, divided by the speed at which you travel that distance. If we reverse that, we get that the speed is equal to the distance traveled over the time taken.
We also know that the time it takes for the Earth to go once around the Sun is 1 year. So in order to know the speed we just have to figure out the distance traveled by the Earth when it goes once around the Sun. To do that we will assume that the orbit of the Earth is circular (which is not exactly right, it is more like an ellipse, but for our purpose it will do just fine). So the distance traveled in one year is just the circumference of the circle. (remember that the circumference of a circle is equal to 2*pi*Radius)
The average distance from the Earth to the Sun is 149,597,890 km. Therefore in one year the Earth travels a distance of 2*Pi*(149,597,890)km. This means that the velocity is about:
velocity=2*Pi*(149,597,890)km/1 year
and if we convert that to more meaningful units (knowing there is 365 days in a year, and 24 hours per day) we get:
velocity=107,300 km/h (or if you prefer 67,062 miles per hour)
So the Earth moves at about 100,000 km/h around the Sun (which is 1000 times faster than the speeds we go at on a highway!)

How fast does the shadow of the sun move across the Earth's surface?
The answer is dependent on the Earth's rotation ... not the sun. Thus the answer varies from 1000 mph at the equator to zero at the poles.
Why does it appear that our shadow changes or moves throughout the day?
The shadow is caste by the Sun. As the Earth is spinning on its axis, so the Sun appears to move across the sky. As it does so, so the cast shadow also moves.
Why does phases of the moon happen if the moon is a full disk?
The moon hasn't got any light of itself, it can only reflect sunlight. When the Earth gets beween the Moon and the Sun, the Earth will cast a shadow on the Moon. Phases of the Moon happens as the Earth's shadow move across the Moon's surface.
Why does a shadow Change depending on the time of day?
The shadow is cast by the sun.As the earth rotates on it's axis, the sun appears to move across the sky in an arc.The height and direction of the sun is constantly changing throughout the day and so the shadow will also change. When the sun is high the shadow is short. When the sun is low, the shadow will be long.
What does a sundial prove?
A sun dial is a graded flat disc, with an upright spike in the middle of it. The spike will throw a shadow that will move across the graded disc as the sun moves across the sky. If the sun dial is correctly aligned, the position of the shadow will tell you what time it is.

Explain how an eclipse is evidence of the earth being sphercial in shape?
Circle because the earth gets the light from the sun makes a shadow of the earth wich is a movig circle in the satespheresinserlysamanthacarlinHightowertrail elm fourthgrade loves the planets
What kind of eclipse happens when the Earth moves into the Earths shadow?
The Earth cannot move into it's own shadow, as the Earth is not a self-illuminating object, such as a desk lamp, which can cast a shadow on itself.
Large bodies of ice that move across earth's surface?
Large bodies of ice that move across the Earth's surface are glaciers.

Idea that continents move slowly across earth's surface is called what?
The idea that continents move slowly across the earth's surface is called the continental drift.
Why does the sun move across the sky in short words?
The Sun doesn't: "move across the sky" Earth revolves around the Sun which is why it appears to "move across the sky".
What movement of earth cause the trees shadow to move during the day?
wind
How fast does the sun travel over the earth?
The sun does not travel over the earth. The earth turns "under" the sun. As a result, the sun appears to move across the sky a the rate of about 15 degrees per hour
