Answer:
a) Jet streams are rapidly moving cold currents that circle the Earth high in the atmosphere. Air currents are caused by the sun's uneven heating of the Earth. ... As the Earth's surface is heated, it warms the air just above it. The warmed air expands and becomes lighter than the surrounding air.
b) North Equatorial Current.
c) Continental drift is the hypothesis that the Earth's continents have moved over geologic time relative to each other, thus appearing to have "drifted" across the ocean bed. The speculation that continents might have 'drifted' was first put forward by Abraham Ortelius in 1596.
d) Ozone depletion, gradual thinning of Earth's ozone layer in the upper atmosphere caused by the release of chemical compounds containing gaseous chlorine or bromine from industry and other human activities. The thinning is most pronounced in the polar regions, especially over Antarctica.
