Ok, people, this is so agitating and time consuming.
Below are some of the solutions to the vista HW.
Make some educated guess and then copy past you answers,
in hear. In a will we will have it all.

The correct answer is the # that has "Student Response" in front of it and in the Score section I it states 1/1, 0/1 means don't pick what was selected by that person as your guess during your submit. Instead pick some thing else

A Universe of Spherical Objects that Follow an Elliptical Orbit

Our Universe is full of spherical objects that follow an elliptical orbit which is similar to the orbit of all other nearby objects. Why is this pattern so pervasive? Our Universe has spherical objects because ...

3. that provides equal gravitational pull for each radial distance from the object's center. Objects must orbit to provide a centrifugal effect that counter-balances the gravitational attraction of nearby objects.

Introductory Geology that Includes the Study of Fossils

Places that use American textbooks for introductory geology virtually ignore fossils in the first-semester course, aptly named "Physical Geology". What do students in the other places learn that American students do not? Among the following topics, the one that other students generally do not learn is ...

Student Response Feedback
1. the names of epochs within the Tertiary Period, i.e., the Paleocene, Eocene, Oligocene, Miocene, Pliocene, and Pleistocene.
2. the major types of dinosaurs in each of the Mesozoic periods, i.e., the Triassic, Jurassic, and Cretaceous.
3. the times when major lifeforms first appeared on Earth, e.g., the great explosion of marine animal life at 545 Ma.
4. how to calculate the age of a bed of volcanic ash, given its ratio of argon-40 to potassium-40.
Student Response 5. how to construct a device to measure carbon-fourteen ages.

Newton Showed that Earth's Density Must Increase Downward

Fig. 1 shows the geometric relationship among the crust, mantle, and core. Three centuries ago, Isaac Newton used his newly-discovered Law of Gravity to calculate that the density of the whole Earth differs from that of the rocks that one may collect on the Earth's surface. As confirmed by modern measurements, Newton found that the difference between the average density of the entire planet and that of its surficial rocks is roughly ...

A Difference between Mantle Convection and Convection above a Bunsen Burner

Convection in the mantle is often likened to convection above a bunsen burner (Fig. 1). However, there are some differences. All but one of the following statements is true. Choose the false statement.

Fig. 1. Convection above a Bunsen Burner
Student Response Feedback
1. Heat input may remain constant for a bunsen burner but must eventually diminish for Earth.
2. The beaker above a bunsen burner may dissipate substantial heat laterally whereas that type of heat loss is immaterial for Earth.
3. The three-dimensional pattern of convection may change in both cases without any apparent change in the input or output of heat.
4. The convecting material above a bunsen burner is liquid, unlike the material convecting in Earth's mantle.
Student Response 5. The source of the heat input is similar in both cases.

Earth's Loss of Hydrogen and Helium


Helium was an important element in the days of dirigibles, the giant gas-filled airplanes used nearly a century ago. Helium was preferred because helium does not burn like the alternative gas, hydrogen, which proved to be disastrous in the Hindenburg fire in 1937 at Lakehurst NJ { http://en.wikipedia.org/wiki/Image:Hindenburg_burning.jpg }. Unlike most chemical elements, both hydrogen and helium are progressively being lost from Earth (Fig. 1). Nonetheless, the amount of helium on Earth is not decreasing as expected from this ongoing loss rate. The reason for this apparent paradox is that helium ...

Fig. 1. Loss of Hydrogen from Planet Earth
Student Response Feedback
Student Response 1. has such a low density that a little helium escapes Earth's gravitational pull every day but more helium is being produced as a byproduct of the radioactive decay of uranium.
2. becomes sequestered within minerals temporarily but later becomes released when those minerals become metamorphosed.
3. reacts with hydrogen to become lithium but this lithium eventually decays back to the original combination of hydrogen and helium.
4. undergoes radioactive decay but this decay is reversible, much like the daily loss and production of carbon-fourteen.

3. a type of marine reptile that is commonly found among the fossils in these rocks, a reptile that was closely related to a plesiosaur.
4. the style of rock deformation in this area, given that the rocks were very pliable at this time.

Ancient Greek and Oriental Civilizations Used a Similar Word for "Planet"

Fig. 1 illustrates the Japanese kanji for "planet". Although this term looks very different from the original Greek word for "planet", literally p?a??t??, both words carry the same basic meaning. In both ancient civilizations, this word conveyed the idea that ...

Student Response Feedback
1. the planets vary more greatly in their magnetic fields than do the stars. Except for its lack of a magnetic field and its high atmospheric temperature, Venus is the planet most similar to Earth. Jupiter and Saturn both have magnetic fields but they are multi-pole fields whereas Earth has a simple dipole field.
2. the planets are all smaller than the stars. To become a star, there must be enough mass that gravity can sustain nuclear fusion, i.e., the coming together (melding) of atoms, even while the resulting explosion is trying to tear those atoms apart.
Student Response 3. the stars go around the night sky in a perfect circle, given the rotation of the Earth around the North Star, but the paths of the planets wander off that circular path.
4. the planets vary more greatly in brightness than do the stars, from Venus with its obvious brightness to the virtually imperceptible Pluto, so far from Earth and so small that it is no longer officially recognized as being a planet.

well kimberly actually tells people to work together on the homework. He claims that is part of your "participation" in class.

this happened before and kimberly said he didn't care when he was told the answers were being shared on TWW.... iirc
