Answer: It describes the formation, breakdown, and reformation of a rock as a result of sedimentary, igneous, and metamorphic processes. All rocks are made up of minerals. ... Igneous rocks- form in two very different environments. Hope it helped!
Answer:
Pros: First of all it is community that can make or break it for me, be it University days, my early career in Toronto or living in the middle of the ocean. I have met the most incredible people, beautiful people born on the islands and many from varied nations that make up our rich ex-pat community. The ex-pats are particularly special to me as we are all in the same boat, so to speak, in that we are looking for community which makes us available on Christmas or Easter, a brunch or a barbecue as we don’t have family on the Island. We become that for each other: celebrators, listening ears and extra hands. We are Island Family.
Cons: It is a very transient place for ex-pats so you are always saying a heart wrenching farewell to one or more of these Island family members. And of course, we all miss our families/friends back home. I know I do.

Answer:
Super position
Faunal Succession
Crosscutting Relationships
Inclusions
Explanation:
Superposition: The most basic concept used in relative dating is the law of superposition. Simply stated, each bed in a sequence of sedimentary rocks (or layered volcanic rocks) is younger than the bed below it and older than the bed above it. This law follows two basic assumptions: (1) the beds were originally deposited near horizontal, and (2) the beds were not overturned after their deposition.
Faunal Succession: Similar to the law of superposition is the law of faunal succession, which states that groups of fossil animals and plants occur throughout the geologic record in a distinct and identifiable order. Following this law, sedimentary rocks can be “dated” by their characteristic fossil content. Particularly useful are index fossils, geographically widespread fossils that evolved rapidly through time.
Crosscutting Relationships: Relative ages of rocks and events may also be determined using the law of crosscutting relationships, which states that geologic features such as igneous intrusions or faults are younger than the units they cut across.
Inclusions: Inclusions, which are fragments of older rock within a younger igneous rock or coarse-grained sedimentary rock, also facilitate relative dating. Inclusions are useful at contacts with igneous rock bodies where magma moving upward through the crust has dislodged and engulfed pieces of the older surrounding rock.
The rock may be sedimentay
