    What causes El Nino to happen?

    • When winds blow from the west

    • When winds blow from the east

    • When ocean water becomes cooler

    • When ocean water becomes warmer

    Correct Answer
    A. When ocean water becomes warmer
    Explanation
    El Niño occurs when ocean water becomes warmer. This increase in water temperature disrupts the normal pattern of ocean currents and wind patterns in the tropical Pacific region. As the water warms, it causes a decrease in upwelling, which is the process of cold, nutrient-rich water rising to the surface. This disruption affects the distribution of heat and moisture in the atmosphere, leading to changes in weather patterns worldwide. El Niño events typically result in increased rainfall in some areas and drought conditions in others.

    Which of the following are consequences of El Nino? Mark all that apply.

    • Severe storms

    • Drought

    • Flooding

    • Tsunamis

    Correct Answer(s)
    A. Severe storms
    A. Drought
    A. Flooding
    Explanation
    El Nino is a climate pattern that occurs when the Pacific Ocean becomes warmer than usual, causing significant changes in weather patterns worldwide. One consequence of El Nino is the occurrence of severe storms, which can lead to heavy rainfall, strong winds, and even tornadoes. Another consequence is drought, as El Nino disrupts the normal rainfall patterns, causing regions to experience prolonged periods of dry weather. Additionally, El Nino can also result in flooding, as the increased rainfall and altered weather patterns can lead to excessive runoff and overflowing rivers. However, tsunamis are not directly linked to El Nino, as they are caused by seismic activities rather than climate patterns.

    According to the article, El Nino typically occurs every

    • Year.

    • Two to three years.

    • Three to five years.

    • Three to seven years.

    Correct Answer
    A. Three to five years.
    Explanation
    El Nino is a climate phenomenon characterized by unusually warm ocean temperatures in the equatorial Pacific region. According to the article, El Nino events typically occur every three to five years. This means that there is a regular pattern of occurrence, with intervals of two to three years being too short and intervals of three to seven years being too long. The frequency of El Nino events within the three to five year range suggests a consistent cycle influenced by various climatic factors.

    ENSO stands for _______________________________________________. (Take care to use the correct spelling.)

    Correct Answer
    El Nino/Southern Oscillation, El Nino Southern Oscillation, el nino southern oscillation, el nino/southern oscillation
    Explanation
    ENSO stands for El Nino/Southern Oscillation. El Nino/Southern Oscillation refers to the periodic changes in ocean temperatures in the equatorial Pacific region. It is characterized by the warming (El Nino) or cooling (La Nina) of the surface waters, which affects weather patterns and climate around the world. The oscillation between El Nino and La Nina phases has significant impacts on rainfall, temperature, and storm patterns, leading to droughts, floods, and other extreme weather events in different parts of the world.
