Question 1 of 5
1. Question
1 pointsConsider the following statements regarding Jet Streams.
1. Jet streams are narrow bands of strong winds that flow over thousands of kilometres predominantly from east to west.
2. Major jet streams are found near the upper levels of the atmosphere, around 9 to 16 km from the earth’s surface.
3. In India, the Tropical jet stream influences the formation and duration of the summer monsoon.
4. Jet streams aid in the faster travelling of Aircrafts.
How many of the above statements is/are correct?Correct
2, 3 and 4 are correct.
The Boeing 747-436 plane was able to achieve a speed of 1,327 kph as it was aided by a strong jet stream generated due to Storm Ciara.
Jet streams are narrow bands of strong winds that flow over thousands of kilometres from west to east. Major jet streams are found near the upper levels of the atmosphere, around 9 to 16 km from the earth’s surface, and can reach speeds of over 320 kph. The jet streams shift to the north or south depending on the season. During winters, the wind current is the strongest. They are also closer to the Equator during winter. The major jet streams are the Polar Front, Subtropical, and Tropical jet streams. In India, the Tropical jet stream influences the formation and duration of the summer monsoon.
Most commercial planes fly at the jet stream level, and a strong jet stream can provide a potent tailwind to a flight travelling from west to east, like the British Airways flight, which flew from New York to London. This helps reduce the travel time for such flights, as their speeds are boosted.Incorrect

Question 2 of 5
2. Question
1 pointsEquatorial counter-currents are unique because
Correct
Equatorial counter-currents are major surface flows that carry water eastward in the Atlantic, Indian, and Pacific Oceans.
They are located near the equator and are sandwiched between two westward-flowing currents, the North Equatorial Current and the South Equatorial Current.
Equatorial counter-currents are unique, in that they flow in the opposite direction of the surface winds. The other major surface currents in the tropics flow in the same direction as the prevailing winds.Incorrect
