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.
According to the ICSM (Intergovernmental Committee on Surveying and Mapping), there are five different types of maps: General Reference, Topographical, Thematic, Navigation Charts and Cadastral Maps and Plans.
Answer:
The correct answer is B: The greater the angle of the fault, the greater the compression of the crust.
The most basic features to form in sedimentary basins under extension are normal faults. <em>Normal faults are generally fairly steep</em>, ie <em>have a high dip angle.</em> A fault will form in the crust when the extensional forces acting on it are great enough to cause failure along a fracture plane.

Answer: Adiabatic temperature gradient is the rate of change in temperature due to pressure under adiabatic conditions.
Explanation:
The rate of change of temperature due to pressure under adiabatic conditions is referred to as adiabatic temperature gradient.
In practice, since in the sea the pressure changes can be considered proportional to depth changes, the adiabatic temperature gradient is usually given as rate of change per unit depth, instead of per unit pressure and for practical purposes and calculations, the unit of depth is often chosen as 1000 m.
The natural and non-natural heat transfer influence the process of adiabatic temperature gradient.
Answer:
South America has diverse agricultural products, vast mineral wealth, and plentiful freshwater. It also has rich fisheries and ports on three bodies of water: the Caribbean Sea, Atlantic Ocean, and Pacific Ocean. The continent's economy is centered on the export of natural resources.
