Answer:
THE MAGNETIC FIELD BECOMES FROZEN INTO ROCKS, AND PLATE TECTONICS SPREADS THOSE ROCKS OUT
Explanation:
we can study the orientation of structures in rocks to determine where the field lines pointed, and by dating those rocks, we can trace the changes of the earth's magnetic field
<span>Taking the age of the earth to be about 4 * 10^9 years and assuming the radius of its orbit has not changed and is circular, calculate the approximate total distance the earth has traveled since its birth (in a frame of reference stationary with respect to the sun)</span>
Answer:
The difference between the purchase with a debit card and the purchase with a credit card lies in the way of financing the amount to be paid. Thus, in the purchase with a debit card, the money with which the purchased good or service is paid is immediately withdrawn from the bank account of the cardholder, with which the debit card works as a cash payment but without use paper money. On the other hand, when paying with a credit card, said amount is not subtracted from the account, but instead a debt is taken with the bank, which must be paid after a certain period.
Just before 1500, Italian amateur actors were performing classical comedies on stages with no decoration except for a row of curtained booths. By 1589, complex painted scenery and scene changes were being featured in production in Florence. And by 1650, Italy had developed staging practices that would dominate European theatre for the next 150 years.
In the beginning of the Renaissance, there were two distinct kinds of theatrical productions. The first was of the type presented by the humanist Julius Laetus at the Accademia Romana, a semisecret society he founded in the mid-15th century for the purpose of reviving classical ideals. In terms of staging, several medieval-type mansions were clustered to form a single large unit. There were, however, two elements not found previously. One was that the mansions were probably framed by decorative columns. This was the first movement toward the framework that would develop into the proscenium arch—the arch that encloses the curtain and frames the stage from the viewpoint of the audience. (The first permanent proscenium was built in the Teatro Farnese at Parma, Italy, in 1618–19, a temporary one having been constructed by Francesco Salviati 50 years earlier.) The second innovation was that the mansions, by being linked, were treated as components of a general city street. In 1508 at Ferrara a background painted according to the rules of perspective was substituted for the mansions; the scene included houses, churches, towers, and gardens.
