Answer:
Fault- B
Extrusion- H
Unconformity- G
Relative Age- E
Law of Superposition- C
Intrusion- D
Absolute Age- A
Index Fossils- F
Explanation:
<u>Fault-</u> A fault generally refers to the fracture as a result of which either the hanging wall goes up or down with respect to the footwall. it takes place either due to compressional or extensional stress. In simple terms, it is a break that occurs in the earth’s crust.
<u>Extrusion-</u> These are the consolidated rocks that are formed when magma comes out to the surface forming extrusive rocks. For example, Basalt and Rhyolite.
<u>Unconformity-</u> It is defined as the period of non-deposition. It occurs when the rocks surfaces are eroded extensively. These are the surfaces where the much older rock meets geologically younger rocks.
<u>Relative age-</u> When the age of any rock is compared with the age of different rocks then, the relative age of the rock is obtained. It is extensively used for the calculation of the age of rocks from any sedimentary sequence.
<u>Law of Superposition-</u> This law enables us to evaluate the relative ages of two or more rocks as it depicts the younger rocks that are deposited on the apex and the older rocks at the bottom of a sequence.
<u>Intrusion-</u> These are the rocks that form due to the crystallization and solidification of magma beneath the earth's surface. For example, granite and gabbro.
<u>Absolute age- </u>This refers to the total amount of time (in terms of years) that a rock has formed. These rocks are formed from the deposition, compaction, and lithification of sediments in a sedimentary environment.
<u>Index fossils-</u><u> </u>These are the fossils that were present for a shorter period of time and have a wide geographical distribution and were mostly used by the geologists in order to match the rock layers.
Answer:
Baptist and Methodist.
Explanation:
The First Great Awakening was a period of spiritual renewal that occurred during the mid-18th century. This period also saw a great deviation from the Catholic belief system and the emergence of more Protestant sect religious churches such as the Baptist and the Methodists.
This spiritual revival and awakening began as a result of the oppressive nature of the Catholic Church of England. Beginning in the American colonies, the religious prosecution led to the revival and emergence or founding of a different Christian belief path such as the <u>Baptists and the Methodist Churches.</u>
Igneous rock derives it's name from the Latin word ignis which means fire. It is formed when the magma after volcanic eruption gets cool and solidified either on the surface of earth crust or inside the earth crust. These rocks are characterized by their hardness. These rocks undergoes no chemical weathering but exhibit very low mechanical or physical weathering may occur. Therefore, hardness is the property which can be used to identify the origin of an igneous rock.
