Suppose we were to place seismographs all around the surface of Europa. When "Europa-quakes" (Europa Earth-quakes) occur all seismographs around the Europa register both transverse, Swaves and longitudinal, P-Waves. What would this tell us about Europa? Europa has neither a molten core nor a liquid water ocean. Europa has a molten core. Europa has an ocean of liquid water under the surface ice. Europa has a molten core but the water on Europa is solid all the way to the rocky surface. Why do strato-volcanoes have steep sides? Their magma comes from magma plumes that form deep inside the Earth. Their magma comes from melted crust that is high in silica. Their magma comes from sub-duction zones which has virtually no silica. Their magma comes from the mantle where there is much less silica. Question 5 6.15 pts Mercury's uncompressed density is much greater than the Earth's uncompressed density. Why is this? Mercury is geologically dead so its core is solid. This makes its density higher. Mercury's iron core is a much higher percentage of its total mass compared to the Earth. Earth is larger than Mercury and therefore gravitational compression is much more important. Earth has water on its surface which accounts for the difference in density. Why does the Lunar Maria have so many fewer craters than the Highlands? The Mare are small areas on the Moon so they look like they have fewer craters. Actually the crater density is the same between the Maria and the Highlands. Meteors come in groups and only hit localized regions. The Maria are places where there just happened to be fewer impacts. The lava that created the Maria covered up the older impact craters. The Maria is mainly on the near-side of the Moon. This is the side at always faces the Earth and the Earth has blocked most meteors from reaching the near-side of the Moon. Question 7 6.15pts Why are the astronauts in the International Space Station (ISS), weightless? The astronauts and the ISS are falling around the Earth. The ISS is too far away from the Earth to feel the effects of gravity. There is no gravity in outer space. There is no gravity in the vacuum of space. The astronauts are too small to be effected by Earth's gravity even though the ISs does feel Earth's gravity. The Earth has a radius that is twice as big as Mars. If it takes Mars 3 billion years to cool down and become geologically inactive, how long would it take the Earth? 6 billion years 1.5 billion years 24 billion years 3 billion years 45 billion years

What is unique about the plate tectonic setting of Iceland?The magma that feeds Icelandic volcanoes comes straight from Earth's inner core and that is indeed rareIceland formed as a result of collision between two continental plates that have long been destroyed by plate subduction process.Iceland has all three plate boundaries within a small geographic region.The Iceland is essentially a manifestation of a mid-ocean ridge that is exposed on land.

The different seasons happen due to the following reasons (choose all the best answers)The 23.500 of the Earth's as sometimes causes one hemisphere to receive longer hours of sunlight per day compared to the other hemisphereThe Earth's orbit sometimes brings it closer to the Son than in other timesOver the year the fit of the Earm's axis of rotation varies from 23.5 to 0 in such a way as to bring more heating per hour in the summer than is the winter The 235 of the Earth's sometimes causes on hemisphere to receive more concentrated sunlight during daylight hours while the other hemisphere receives more spread out and weaker sunlightThe 225 ill of the Earth's as sometimes cames one hemisphere to be significantly closer to the Sun than the other hemisphere

The current population of Tanzania is 50.3 million with a population growth rate of 2.14% per year. The average annual agricultural yield in Tanzania is 8,670 kg/ha (where "ha" means hectare, which you can think of as a metric acre), a yield that is comprised of both grains (e.g. maize/corn) and tubers of about 1.5% per year for the last five years or so. Ideally, one person should have a caloric intake of at least 2000kcal per day in order to maintain their 1 kg grain supplies 3000 kcal; 1 kg tubers supplies 1000 kcal. Use the equations from our mini-lecture and the linear growth equation from the last module quantitative assignment, to answer the following questions. You will also have to do some conversions for which you won't find specific equations. answer to one place past the decimal and put your answer in "millions", so that if your answer is 55,670,000 your answer is 55.7 Million and yould enter 55.7 as your answer. Answer: 56.6
