Answer:
Explanation:
1....Which of the following occurs when a neutron strikes a radioactive parent atom?
fission
Fission occurs when a heavy nucleus spontaneously disintengrates into lighter ones. When neutron strikes a parent atom, it becomes unstable and in the process disintegrates.
2......Fission occurs when a neutron strikes a radioactive parent atom, causing it to split into smaller daughter atoms and in the process releasing
energy
Fission is accompanied by the release of energy after daughter atoms are formed. These energy are tapped for use in nuclear power plants.
3......A facet is a __________ on a gem.
Polished surface
A facet is a smooth polished surface of gem that has been well cut.
4........The groundwater quality of an aquifer is tested and found to have high amounts of arsenic. It is likely that the arsenic
comes from the dissolved minerals in the aquifer rock
For arsenic to be found in ground water, the geology of the area must have had a telling effect on the water body.
5............Where would you expect to find geysers?
Iceland
In Iceland, the mid-atlantic ridge cuts the continent and it can be visibly seen on the surface.
A geyser is a hot spring that in which columns of hot water sprout out intermittently.
Magma bodies are closer to the surface in Iceland where they can come in close contact with the ground water system thereby sending super heated water in form of steam and vapor outwards. This is the geyser seen on land.
6.........Important volatiles in magmas include __________ .
water and carbon dioxide
Water and carbon dioxide are the most important volatiles which are found in magmatic bodies.
7.....Granite, a course-grained, felsic intrusive igneous rock is most similar in mineral composition to __________ , which is a fine-grained, felsic extrusive equivalent.
rhyolite
Ryholite is the extrusive equivalence of granite. Both rock types are felsic and are rich in silica and feldspar. Their silica composition above 60%.
8.........Which of the following is most typical of what you would find in a lahar?
water and mud
Lahars are examples of volcanic mudflow in which water and volcanic mud flows down slope.
