Answer:

Option (A)

Explanation:

<u>Sandstone is the main rock of the Theodore Roosevelt National Park</u>. This rocks were formed some 65 million years back, that marked the boundary of the cretaceous mass extinction that wiped out the entire dinosaurs species from earth.

During the Paleocene age, towards the western side of North America, there was continuous folding of beds due to the compressive forces, thereby forming the Rocky mountains. And this mountain over the course of time undergone significant weathering and erosion by wind, water and ice, due to which a huge amount of sediment has been accumulated at the eastern side. These sediments were mostly silt, sand and mud. In addition to that, continuous volcanic eruptions has also taken place in the nearby places, from which the  abundant volcanic ashes were released and subsequently got mixed up with the eroded sediments. Therefore, after millions of years, this rocks undergone compaction and lithification, and turned into sandstone.

Thus, the correct answer is option (A).

10. If water is the transport medium of sediment, the grain size of sedimentary depositsmost closely indicates the ____________.
bulgar [2K]

Answer: If water is the transport medium of sediment, the grain size sedimentary deposits most closely indicates:

(B) average velocity of the water from the time of erosion until deposition.

Explanation: Here, the average velocity of the water determines the sorting of the grain size.

If the average velocity is high like that of the beach, the grain size will be well sorted.

But if the average velocity is low like that of a stream, it would be poorly sorted.

RideAnS [48]

<u>Answer</u>:

<em>A break that isolates more seasoned changeable rocks from more youthful sedimentary shakes promptly above them is a sort of unconformity called a nonconformity.</em>

<u>Explanation:</u>

<em>A rebelliousness is a break that different previous (changeable rocks or volcanic rocks) from overlying sedimentary rocks.</em>

An nonconformity is a contact between two shake units where the upper unit is are commonly covered erosional surfaces that can speak to a break in the geologic that isolates a more youthful sedimentary shake unit from a molten meddlesome <em>shake or shake at the surface before it was at long last covered by the more youthful shakes above it.</em>
