an iridium-rich layer of clay, glass spherules, and shocked quartz grains marks the extinction event at the end of the a) permian b) cretaceous c) ordovician d) triassic e) devonian
10. The age of the reptiles, the Mesozoic era, is marked by the rise of the phytoplankton (including diatoms & dinoflagellates), the great radiation of reptiles, and the dominance of the seed plants. The first mammals appear in the Triassic, but they are not a dominant species. Note the “small” mass extinction at the end of the Triassic. Flowering plants also appear and diversify in the Jurassic, but like the mammals, the do not dominate the biosphere. It isn’t until...

Considering the rotation of the Earth only, compare your apparent weight on the North Pole and on the Equator.
The aviation industry is described as the most fickle industry on earth. Compare and contrast the financial history of the industry's operational costs to other industries. Discuss this impact on its success or failure.
The total power consumption by all humans on earth is approximately 1013 W. Let�s compare this to the power of incoming solar radiation. The intensity of radiation from the sun at the top of the atmosphere is 1380 W/m2. The earth's radius is6.37�106 m. What is the total solar power received by the earth? By what factor does solar power received by the earth exceed the total human power consumption?
5. An astronaut orbits the earth in a space capsule whose height above the earth is equal to the earth's radius. How does the weight of the astronaut in the capsule compare to her weight on the earth? A) It is equal to her weight on earth. B) It is equal to one-half of her weight on earth. C) It is equal to one-third of her weight on earth. D) It is one-fourth her weight on earth. E) It is...
