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.

Answer:
The answer is "Option D".
Explanation:
The conquerors of Spain was mainly robbers. They tried to gain their shareholders land or riches and also to capture the treasuries and glory for natives of many other countries, Throughout the spread or execution of religion, they were also vital. For the Aztecs and Incas, it was a very chaotic period and Such disease also resulted in the death of millions and Spain could strike in its vulnerable state.
A high pressure area is an area where the air sinks. As it does, it warms up by the adiabatic effect of a greater pressure and that causes the clouds to evaporate, giving place to a clear sky
Answer:
latitudes that are (a) and (b)
longitudes that are (c) and (d)
Explanation:
we get here line of latitudes that are
for
(a) N 34 08' 44.9"
it is north 34 degree 8 minute 44.9 seconds
it is Northern Hemisphere
and
(b) S 18 09' 30.3"
it is south 18 degree 9 mint 30.3 seconds
it is Southern Hemisphere
and
here
(c) E 10 25' 41.3" and ( d) W 118 07' 02.3"
they are not at line of latitude
they are at line of longitude because east and west
as we know that N and S are at Latitudes
and E and W are at longitudes
