13, El Niño events are often followed by La Niña events, which are characterized by
:A) accentuated normal oceanic and upwelling currents--------answer
.B) extreme El Niño-like disruption of normal oceanic and upwelling currents.
C) cessation of all oceanic circulation for a year or more
.D) return of normal rainfall patterns in tropical and temperate zones.
E)a rare opportunity for farmers in temperate zones to grow tropical crops for a few years
.Answer: A
El Niño is an atmosphere cycle in the Pacific Ocean with a worldwide effect on climate designs. The cycle starts when warm water in the western tropical Pacific Ocean moves eastbound along the equator toward the shoreline of South America. Typically, this warm water pools close Indonesia and the Philippines.

In humid tropic , laterization is an important soil forming process. Which of the following is a result of this process
Development of reddish coloration
Loss of silica through leaching
Reduced capacity of solid to hold nutrients
All of the above-answer
Tropical weathering (laterization) is a drawn out procedure of concoction weathering which creates a wide assortment in the thickness, review, science and metal mineralogy of the subsequent soils.The starting results of weathering are basically kaolinized rocks called saprolites. A time of dynamic laterization stretched out from about the mid-Tertiary to the mid-Quaternary time frames (35 to 1.5 million years prior). Measurable examinations demonstrate that the move in the mean and difference levels of 18O amid the center of the Pleistocene was abrupt. It appears this unexpected change was worldwide and fundamentally speaks to an expansion in ice mass; at about a similar time an unexpected reduction in ocean surface temperatures happened; these two changes show a sudden worldwide cooling. The rate of laterization would have diminished with the sudden cooling of the earth. Weathering in tropical atmospheres proceeds right up 'til the present time, at a diminished rate
