Natural Hazards

What is a characteristic of constructive plate boundaries?

• They are associated with earthquakes

• Magma rises to form new crust

• Plates move towards each other

• They cause explosive volcanic eruptions

What is the focus of an earthquake?

• The location where the earthquake begins underground

• The point on the surface above the earthquake

• The center of tectonic activity

• The area most affected by the earthquake

Which condition is necessary for the formation of tropical cyclones?

• Ocean surface temperature below 20°C

• High wind shear

• Ocean surface temperature of at least 27°C

• Presence of cold ocean currents

What is a common human cause of flooding?

• Saturated soil

• Heavy rainfall

• Deforestation

• Snowmelt

What is one impact of drought?

• Higher humidity levels

• Flooding of low-lying areas

• Increased crop yields

• Water sources dry up

What is a method used to predict volcanic eruptions?

• Monitoring rainfall patterns

• Using seismometers to monitor tremors

• Tracking animal behavior

• Mapping population density

What is a consequence of tropical cyclones?

• Improved water supply

• Lower sea levels

• Flooding from storm surges

• Increased agricultural productivity

What is the primary cause of earthquakes at conservative plate boundaries?

• Plates colliding

• Plates sliding past each other

• Plates moving away from each other

• Magma rising to the surface

What is one way to manage the impacts of flooding?

• Reducing vegetation

• Ignoring drainage systems

• Building levees and flood barriers

• Increasing urbanization

What is a significant effect of climate change on drought?

• Increased rainfall in all areas

• Higher temperatures leading to less rainfall

• More frequent flooding

• Improved water supply
