Does it look to you, that the Sun and the Moon are moving around a stationary earth? Do your eyes tell you that the Sun and the Moon are the same size? Does your skin tell you that the Sun is closer than 93 million miles? Do your senses tell you that the earth is spinning 1000 MPH? Did your teacher tell you that the globe is a model of the earth? Who are you going to believe?

@Joe Riley Strangely enough, last few days I was thinking about exactly that: every 24 hours, the earth completes a revolution. If we call it's circumference 24,000 miles, that means at it's Equator the surface of the easrth is moving at about 1,000 miles per hour. If you are standing on the equator somewhere, you are also moving 1,000 mph along with the surface of the earth (ignoring the movement about the Sun). But what if you are NOT on the Equator? The Earth rotates about an axis passing through it's "Poles", at north and south. Somewhere between the Equator and the poles there lie two imaginary line encircling the Earth and paralleling the Equator, called Tropic of Cancer and Tropic of Capricorn; these have to do with the Sun's position as the Earth "precesses" from Season to Season. The point is, standing on either of those "Tropics" results in your actual speed being much less than 1,000 miles per hour. Taken to the extreme, if you stand directly on the point called a "Pole", either north or south, your speed will be essentially zero miles per hour, though you will rotate about one turn each 24 hours. This is because Velocity is defined as "rate of change of location", or speed per unit time; at a point, no distance is traversed as the point rotates. Does any of this drivel make any sense? Frank

The Earth is spinning at 1000 MPH only on the Equator, Frank! Where I live, it's spinning at (1000 x cos 34.5),or 824 MPH (My latitude is 34.5 degrees North) And your post is NOT DRIVEL, Frank, because, it makes absolute sense to ME! Howl

@Hal Pollner Exactly. Thought about determining quantitatively the distance between latitude lines at the equator. Maybe tonight. Frank

@Shirley Martin Yes, it is, because the forces generated by the Earth spinning on it's axis "draw" it out just a bit at the Equator, and squish it down a bit pole to pole. Frank

WAIT, Frank.....my first post used the sin function, which is incorrect! It's the cos function that's correct! At the equator, the latitude of zero degrees is zero, and the cos function of zero is unity, making the speed at the equator 1000 MPH. At the Pole, the latitude is 90 degrees, and the cos function of 90 is zero, which is the rotational speed at the North Pole. My High School Trigonometry comes back to me! Hal

Hold it, Frank...there's only ONE latitude line at the equator and that is zero degrees, minutes, and seconds. Perhaps you mean Longitude lines? If so, then you can divide 24 hours of Longitude into 360 degrees of the Earth's circumference, giving you 15 degrees per hour of Longitude. Yup Yup Yup! Hal

@Hal Pollner Remember the 38th. parallel? It was a LATITUDE line thus: "The 38th parallel north is a circle of latitude that is 38 degrees north of the Earth's equatorial plane. It crosses Europe, the Mediterranean Sea, Asia, the Pacific Ocean, North America, and the Atlantic Ocean. The 38th parallel north formed the border between North and South Korea prior to the Korean War." https://en.wikipedia.org/wiki/38th_parallel_north
