Total questions: 10
Worksheet time: 5mins
What are the primary causes of earthquakes?
Animal behavior
Movement of tectonic plates, volcanic activity, human activities, and fault lines.
Ocean currents
Weather changes
How do earthquakes affect buildings and infrastructure?
Earthquakes have no impact on buildings or infrastructure.
Earthquakes can cause structural damage to buildings and infrastructure, leading to cracks, collapses, and disruptions in services.
Earthquakes only affect the landscape, not man-made structures.
Earthquakes improve the stability of buildings and infrastructure.
What is a tsunami and how is it generated?
A tsunami is generated by the gravitational pull of the sun and moon.
A tsunami is a series of ocean waves generated primarily by underwater earthquakes, volcanic eruptions, or landslides.
A tsunami is caused by high winds and storms in the ocean.
A tsunami is a type of tidal wave that occurs during full moons.
What coastal impacts can tsunamis have on communities?
Tsunamis can cause flooding, destruction of infrastructure, loss of life, contamination of water supplies, and coastal erosion.
Tsunamis have no impact on local wildlife.
Tsunamis only affect ocean currents.
Tsunamis can improve coastal tourism.
What are the main hazards associated with volcanic eruptions?
Earthquakes, tsunamis, and landslides
Lava flows, ashfall, pyroclastic flows, volcanic gases, lahars.
Flooding from heavy rainfall
Wildfires caused by dry conditions
How can volcanic eruptions affect air travel?
Ash clouds from eruptions create beautiful sunsets, attracting more flights.
Volcanic eruptions can disrupt air travel by creating hazardous ash clouds that damage aircraft and lead to flight cancellations.
Volcanic eruptions have no impact on flight schedules or safety.
Volcanic eruptions improve air quality, enhancing flight safety.
What are the common causes of flooding in urban areas?
Drought conditions
Excessive snowfall
Earthquake-induced tsunamis
Common causes of flooding in urban areas include heavy rainfall, inadequate drainage systems, urbanization, and poor land management.
How can effective water management mitigate flooding risks?
Effective water management reduces flooding risks by controlling water flow and enhancing absorption.
Diverting rivers to create more flood zones
Increasing water flow to prevent stagnation
Reducing vegetation to enhance runoff
What factors contribute to landslides in hilly regions?
Lack of vegetation cover
High temperatures
Heavy rainfall, earthquakes, soil erosion, deforestation, and geological conditions.
Urban development
How does soil stability influence the occurrence of landslides?
Soil stability influences landslides by determining the soil's ability to resist gravitational forces; unstable soil increases landslide risk.
Increased soil stability always reduces landslide risk.
Landslides only occur in rocky terrains, not in soil.
Soil stability has no effect on landslides.
