Learning objective

Students should be able to describe and explain the effects of natural hazards on individuals and the environment, including: tectonic events causing damage to structures and infrastructure, fires, tsunamis, landslides, loss of agricultural land and habitats, waterborne diseases, fatalities, psychological trauma, and economic impacts; tropical cyclones leading to flooding, fatalities, economic losses, damage to structures and infrastructure, loss of crops and habitats, and waterborne diseases; flooding resulting in fatalities, loss of livestock and crops, damage to structures and infrastructure, contamination of drinking water, waterborne diseases, and economic losses; droughts causing organism deaths, depletion of water sources, reduced crop yields, starvation, increased soil erosion, desertification, poorer air quality, and heightened wildfire risks.

Read the explanation, check the common trap, then practise with flashcards and questions.

Description

Tectonic Events and Their Effects

Tectonic events such as earthquakes and volcanic eruptions can cause damage to buildings and infrastructure, loss of agricultural land and habitats, fatalities, psychological trauma, and outbreaks of waterborne diseases.

  1. a

    Describe two effects of tectonic events on the environment.

    Aim for approximately 2 distinct marking points.
