D every parallel is the same length is the answer
Answer:
The scientist should study the pattern extensively and try as much as possible to be able to describe and predict some of the features of the pattern. He then should make this known to the science world to encourage research into this new field of study.
Explanation:
Discovery is the dream of all scientist. Science is the probe of nature in order to seek and be able to explain and predict a pattern in nature. Discovering a pattern either by probe or by mere coincidence triggers an extensive research and experimentation in this new field. A scientist therefore should make a new discovery know as this not only furthers the advancement of knowledge, but also puts down his own name in history and also lots of immediate recognition.
Answer:
Geographers spend time comparing conditions in different places and regions of the world in order to compare or differentiate landforms, climates, economies, people and cultures and maybe even resources.
Explanation:
For instance, if you know that all the countries in the different continents were combined as a super continent before continental drift came into being, you would realise that certain countries in South America may have particular features or something similar to those of Australia or any other country. In can either be through the finding of fossils, landforms, etc.

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.
