Jet streams in the northern hemisphere: are zones of especially fast-moving high

Question

Jet streams in the northern hemisphere:

are zones of especially fast-moving high-altitude easterlies.

flow at speeds between 50 and 100 km/h.

originate where pressure gradients are at their lowest.

originate over the polar front (60° latitude) and over the horse latitudes (30° latitude).

Which of the following is NOT a contributing factor to regional climate?

proximity to especially warm or cold ocean currents

proximity of water

proximity to isothermic barriers

d. latitude and altitude

Which of the following statements is FALSE? Earth’s atmosphere:

in some locations contains enough sulfates and nitrates to create acid rain.

is becoming more polluted due to the burning of fossil fuels.

contains aerosols, which are tiny droplets of water and acid and particles of sea salt, volcanic ash, clay, soot, and pollen.

is composed of 78% oxygen, 21% nitrogen, and 1% trace amounts of various gases.

are zones of especially fast-moving high-altitude easterlies.

flow at speeds between 50 and 100 km/h.

originate where pressure gradients are at their lowest.

originate over the polar front (60° latitude) and over the horse latitudes (30° latitude).

Explanation / Answer

Jet Stream in northern hemisphere originate over the polar front (60 lat) and over the horse lat (30 lat). These fast moving meandering winds in the atmosphere and are produced due to solar radiation and coriolis force. Proximity of water is not a contributing factor of a regional climate, while all others contribute to change in the environmnet Optiom (d) is composed of 78% oxygen, 21% nitogen and...................... is False because earth contains 78% nitogen, 21% oxygen and !% other
