Young mountains rise in the west. The most familiar of these mountains are probably the Rockies, North America's largest chain. The Rockies stretch from the province of British Columbia, Canada, to the U.S. state of New Mexico.
Answer:
Trade wind blows from the east to the west direction
Explanation:
The trade winds are usually defined as those wind that blows from the tropics of both the hemisphere and moves towards the equator. They originate from the northeastern and southeastern direction in the northern and southern hemisphere respectively.
This wind blows from the east to the west, and as it blows it carries the hurricanes and other types of cyclones. It helps in increasing the growth and strength of hurricanes. The intensity of the trade wind decreases as the hurricane moves over the vast oceans and reaches the land areas or the continent.
Answer:
Option (A)
Explanation:
In the above-given question,
Option (B) is wrong with it's usage of the modifier "how'' in the sentence. If the modifier is used in one place (how heat from the inner core flows), it should also be used in the continuing clause (how the formation and periodic reversal).
Options (C) and (D) are wrong in using the word "are" for the whole sentence as there is no need to use this word. The verb form will depend on the subject, in this case, is "the discovery that earth's inner core" which is singular in nature. Thus, the verb form will be -is and not -are.
Option (E) is wrong for it's use of the comma. If the comma is used, then the whole sentence is not a full-fledged sentence but rather a dependent clause with no resolution.
The correct answer for the given passage is option (A).
Data collected by the drilling ship Glomar Challenger confirmed that none of the ocean floor is more than about 180 million years old.
Glomar Challenger began drilling on both sides of the mid-ocean ridges to gather data. The data confirmed what the sea-floor spreading hypothesis predicted. The ocean floor is youngest along the central valley of the mid-ocean ridge while the ocean floor in subduction zones or near the edges of the continents is oldest. The data has confirmed that none of the ocean floor is more than 180 million years old because the older oceanic rock will undergo subduction and go back to the earth's mantle.
An oxbow lake starts out as a “meander” in a river (like an S-shaped curve). It’s usually on a flat plain. A lake forms when the river finds a shorter, straighter route, leaving water behind in the S-curve.
