Question

el niño begins with which of the following?
the westward movement of winds and currents in the pacific
heavy mudslides in california and tornadoes in florida
upwelling of cold ocean water
the eastward movement of winds and currents in the pacific

Explanation:

El Niño is a climate pattern that involves changes in ocean currents and winds. It begins with the weakening of the trade winds (which normally blow westward) in the Pacific, allowing warm water to move eastward. This eastward movement of winds and currents is a key initial indicator of an El Niño event. The westward movement is more typical of normal (non - El Niño) conditions. Upwelling of cold water is more associated with La Niña (the opposite climate pattern), and heavy mudslides and tornadoes are impacts of El Niño, not its starting point.

Answer:

the eastward movement of winds and currents in the Pacific
