If a space probe sends back info on an object traveling through space at close to the speed of light astronomers will be working
with speeds of: A.) billions of meters per second
B.) trillions of meters per second
C.) millions of meters per second
D.) hundreds of meters per second.
The speed of light in a vacuum is 300,000,000 m/s That is three hundred million meters per second. Therefore, the answer is C) millions of meters per second
1) Plates movement happens very slowly. 2) The earth's lithosphere is divided into pieces 3) they are caused by convection currents in the asthenosphere (upper mantle)
