    Study Notes

    Environmental Science - Quarter 3, Module 2

    • This module explains the causes and effects of natural disasters on humans and their environment.
    • The module follows the standard course sequence.
    • Students are expected to understand the causes and effects of natural disasters on humans and the environment.

    What I Need to Know

    • The module is designed to help students learn about natural disasters and their effects.
    • The language used is appropriate for different learning levels.

    What I Know (page 6)

    • Students are to create an information chart about natural disasters.
    • The chart should include an introduction, information sheet on earthquakes, floods, typhoons, and volcanic eruptions.
    • A concluding statement should be included.

    Lesson 1: Causes and Effects of Natural Disasters (page 7)

    • Students learned about pollutants in a previous lesson.
    • Pollutants harm the environment and humans.

    What's New (page 8)

    • Natural disasters can be categorized as natural or man-made.
    • Common natural disasters include thunderstorms, severe rainfalls, cyclones, earthquakes, volcanic eruptions, and floods.
    • Natural disasters lead to loss of life and destruction of property.

    What Is It (page 9)

    • Natural disasters have atmospheric, geological, and hydrological origins.
    • UNISDR definitions include loss of life, injury, damage to property, loss of livelihoods, and environmental damage.
    • Mitigation measures can minimize loss.
    • Philippines has resources like PAGASA and PHIVOLCS for warnings.
    • Some common disasters include floods and are due to excessive water in rivers and streams overflowing banks.

    Cause of Earthquakes (page 11)

    • Earthquakes occur due to an imbalance in the Earth's crust.
    • Other causes include volcanic eruptions, faulting, and folding, plus internal pressure.

    Effects of Earthquakes (page 11)

    • Earthquakes cause landslides and debris falls; damage to buildings, roads, rails, factories, and bridges.
    • Government infrastructure can be severely damaged.
    • Fire hazards, landmass deformations, and flash floods are also possible effects.
    • Tsunamis can be generated resulting in loss of life and property.

    Cause of Typhoons (page 11)

    • Typhoons are low pressure systems over warm waters of greater than 26°C in the northwest Pacific basin.
    • Factors that influence typhoon development include warm ocean water, a stable atmosphere, and moist air.

    Effects of Typhoons (page 11)

    • Typhoons lead to flooding, destruction of livestock (when exposed), and possible soil erosion when extreme rain causes issues.

    Disaster Risk Reduction and Management in the Philippines (page 12)

    • Philippines is geographically prone to disasters.
    • Tropical cyclones, floods, and other hydro-meteorological perils cause widespread damage and casualties.

    Disaster Response (page 13)

    • Institutional mechanisms for response operations and improved skills in search, rescue and retrieval are needed.

    Activity 1: Matching Disaster (page 13)

    • Students are to match the name of a natural disaster with its appropriate illustration.

    Guide Questions (page 14)

    • Students are asked to define natural disasters, as well as give examples.

    Assessment (page 18)

    • Multiple choice questions regarding natural disasters (causes and effects).

    Additional Activities (page 20)

    • Students are tasked to make an information flyer about natural disasters, causes, effects, and prevention.
