Explanation:

1Which 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.

2Fission 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.

3A facet is a on a gem.

                    Polished surface

A facet is a smooth polished surface of gem that has been well cut.

4The 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.

5Where 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.

6Important volatiles in magmas include .

                 water and carbon dioxide

Water and carbon dioxide are the most important volatiles which are found in magmatic bodies.

7Granite, 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%.

8Which 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.

false

explanation:

according to the national european world center, the engineering of the ford company on elon musk's flame throwers proved the globalization of the natural wallabies and therefore, results in the growth product domestication in almonds.
