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).
Answer:
Central America and the Caribbean span the deep tropics and subtropics. Because of the tropical maritime location temperature changes throughout the region are generally small, and rainfall is by far the most important meteorological element. In general the climate of the region is controlled by the migration of synoptic features, and the mean climate strongly reflects the annual cycle of these features.
The most dominant synoptic influence is the subtropical high of the north Atlantic. Subsidence associated with the spreading of the subtropical high from the north Atlantic to the north American landmass dominates during boreal winter, as do the strong easterly trades found on its equatorward flank. Coupled with a strong trade inversion, a cold ocean and reduced atmospheric humidity, the region is generally at its driest during the winter. With the onset of boreal spring, however, the subtropical high moves offshore and trade wind intensity decreases, with convergence characterizing.
