Answer:
A. Sedimentary rocks of Precambrian age
Explanation:
As most of the sedimentary rocks contain mineral deposits like shale, quads, calcite. Amongst all major types of rocks sedimentary rock are commonly known for fossil deposits and fossil in the end consist of a thin layer of carbon the process is known as Carbonisation and is responsible for formation of fuels and coal etc.
Answer
- 23.32°
- x=4637.16 feet
- y=1999.8 feet
- Explanation
Sketch a triangle ABC, where A is at the apex(top) and BC is the base.Let side AB=5050 feet and BC=6000feet.Drop a perpendicular line from A to BC at O to represent distance y and OB is distance x.
Point A = your location
Point B=First tower and Point C is the second tower.
To calculate the angle in degrees we use law of cosines,
2420²=5050²+6000²-(2)(5050)(6000)(cosB)
B=23.32° is the angle in question
Secondly, we find value of x
CosB=x/5050
X=4637.16feet, the position east of the tower
Thirdly, we calculate y
SinB=y/5050
0.39599=y/5050
y=1999.77
y=1999.8 feet , the position north of the tower
Answer:
Image result for is the continental divide in the eastern or western part of the united states
The Eastern Continental Divide runs along the high ridges and peaks of the Appalachian Mountains, and it separates land draining east to the Atlantic Ocean from that draining west and southwest to the Mississippi River, and the Gulf of Mexico.

<u>Answer:
</u>
The process of thick sediment layers to "accumulate" along the "boundaries of continental and oceanic plates" is called Subduction.
<u>Explanation:
</u>
- During a marine transgression, sea level raises high compared to land level resulting in floods. These are triggered during climate changes, ice-age, isostatic movements.
- Subduction occurs at the tectonic plates where one plate is moves under another forcing to sink into Earth’s mantle due to the gravitational force.
- The plates are continental and oceanic in the zone of lithosphere. The rate of subduction is usually seven to 8 centimetres per year.
- Marine regressions are opposite to transgressions where sea levels fall compared to land levels.
- Glaciation is the interval of time within an ice-age. The current glacier period is of Holocene.
