¶ … components to the principle of uniformitarianism: the first is that the principles that can be applied to the Universe nowadays have always been applicable in the same manner. The second implies that these principles occur and are applicable everywhere in the Universe. With this in mind, if occasional catastrophic events such as the ones described have occurred in the past on Earth, they could occur again, in a similar manner, today or in the future. So, if the dinosaurs became extinct following a meteorite impact, another such impact could hit the Earth in a similar manner, leading to another large scale extinction. Geologic processes include diverse ways in which the Earth's surface is modeled. These include soil erosion or desertification. If an area has been significantly eroded, this could lead to devastating floods. At the same time, other geologic processes can lead to tsunamis. As a consequence, it is obvious that the geologic processes have a positive or negative impact on our daily lives. Depending on where the individual is located, this can be more significant: for example, if one lives in a country such as Indonesia, geologic processes such as volcano eruptions have a stronger negative impact than in a country in Europe.

3. The rock would be igneous. One of the basic characteristics of igneous rocks is that these are formed through a solidification process of molten lava....

This is the case here, since the magma is eventually solidified into the rock itself. A good example of circumstances that might form rocks that are intermediate between two major rock families are metamorphic tocks. This types of rocks were actually either igneous or sedimentary rocks in first phase of formation, becoming eventually metamorphic rocks through a metamorphosis process.
4. The key to answering this question is that minerals are naturally made up of pure elements (or a combination of pure elements, such as salts). As a consequence, from the list, diamond, emerald or a gold nugget could be considered as minerals, following the definition. A synthetic diamond would not be considered a true mineral.

5. One could find out how old the rocks are by identifying, first of all, the way these rocks were formed. This would give a general temporal interval, since metamorphic rocks, for example, would be younger rocks. It would be difficult, however, to date the rocks more specifically without a proper scientific testing and analysis.

6. If one chooses the Jurassic period, the rocks in this period are generally sediments, particularly sediments in the sea and on land. The most characteristic fossils are dinosaur fossils, in various forms. The rocks and fossils are generally found underneath the Earth's crust.

7. The main difference between the two planets that led…
