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.
The answer is B. Lake Victoria. If you look at a physical map of Africa, you will get this answer. The Great Rift Valley is through the center of Djibouti. The Indian Ocean is east of INDIA, not even close to Africa. I hope this helps!
Answer:
abyssal clay is not an example of biogenic sediments .
Explanation:
Any sediment containing more than 30% of organic matter in it , is called as biogenic sediment or biogenic ooze.
The two most common types of biogenic oozes are calcareous and sileceous.
abyssal clays are the fine grained sediment particles that are settled in the deep ocean basins.
abyssal clay mostly consists of land derived eroded particles and have less than 30% of organic matter in them ,
Hence , abyssal clay is not an example of biogenic sediment.
Momentum is a VECTOR quantity because it involves MAGNITUDE AND DIRECTION.
A vector quantity is a quantity which has both magnitude and direction. The formula for momentum is mass x velocity. The mass is a scalar quantity while the velocity is a vector quantity; scalar multiply by vector quantity will give vector quantity .<span />
