Answer:
539 cm²
Explanation:
Height of the cylinder, h = 14 cm
Base diameter = 7 cm
Base radius, r = 7/2 = 3.5 cm
Volume of the cylinder = πr²h = 22(7) × (3.5)² × 14 = 539 cm²
Your teacher is talking about spheres of the earth system. Spheres of influence which effect one another. She probably means earth ecology etc. The answer depends on her definition of the spheres of the earth. You need to know those three sphere definitions before you can answer the question.
<span>Planetary orbit system theories include heliocentric and geocentric theories. Heliocentric theory says the sun is the center of our solar system. Geocentric theory says the earth is the center of our solar system. One aspect of the scientific method is the necessity to suspend judgment in order to entertain the possibility of other answers. This helps us to reduce and minimize the effect of prejudice and emotion as we try to be as logical as possible in our fact gathering. Although we all see the sun rise and fall every day and it appears the earth is flat, it was not until we could suspend judgment and consider other possibilities that we could become more enlightened about the larger picture which includes other planets, the solar system, the galaxy, and the universe. Although it appears the sun orbits the earth, now we know that we orbit the sun. Waxing and waning of moons and planets provide clues to the sun as the center of our solar system and not the earth. </span>
<span>The moon was excised from the earth in a relatively gentle event involving a chain of meteors perforating our ancient equator. The moon then left the earth and succumbed to gravitational influence of the earth so that its one side always faces us as the earth revolves. There was very little angular momentum imparted to the moon when it was created so it left no debris field or ring around the earth and it "locked into phase" with the earth so it does not rotate relative to the earth. The gentleness of the moon's creation also explains why it has no iron from the earths core in it.</span>
Explanation:
Alchemy was the name given in Latin Europe in the 12th century to an aspect of thought that corresponds to astrology, which is apparently an older tradition. Both represent attempts to discover the relationship of man to the cosmos and to exploit that relationship to his benefit. The first of these objectives may be called scientific, the second technological. Astrology is concerned with man’s relationship to “the stars” (including the members of the solar system); alchemy, with terrestrial nature. But the distinction is far from absolute, since both are interested in the influence of the stars on terrestrial events. Moreover, both have always been pursued in the belief that the processes human beings witness in heaven and on earth manifest the will of the Creator and, if correctly understood, will yield the key to the Creator’s intentions.
Nature And Significance
That both astrology and alchemy may be regarded as fundamental aspects of thought is indicated by their apparent universality. It is notable, however, that the evidence is not equally substantial in all times and places. Evidence from ancient Middle America (Aztecs, Mayans) is still almost nonexistent; evidence from India is tenuous and from ancient China, Greece, and Islamic lands is only relatively more plentiful. A single manuscript of some 80,000 words is the principal source for the history of Greek alchemy. Chinese alchemy is largely recorded in about 100 “books” that are part of the Taoist canon. Neither Indian nor Islamic alchemy has ever been collected, and scholars are thus dependent for their knowledge of the subject on occasional allusions in works of natural philosophy and medicine, plus a few specifically alchemical works.
Nor is it really clear what alchemy was (or is). The word is a European one, derived from Arabic, but the origin of the root word, chem, is uncertain. Words similar to it have been found in most ancient languages, with different meanings, but conceivably somehow related to alchemy. In fact, the Greeks, Chinese, and Indians usually referred to what Westerners call alchemy as “The Art,” or by terms denoting change or transmutation.
Answer:
Ring of Fire
Explanation:
The world's greatest earthquake belt, the circum-Pacific seismic belt, is found along the rim of the Pacific Ocean, where about 81 percent of our planet's largest earthquakes occur. It has earned the nickname "Ring of Fire".
