Natural Hazard

A natural hazard is a naturally occurring event

that has the potential to cause harm

or damage to people, property, or the environment.

Types of Natural hazards

Geophysical (earthquakes, tsunamis)

Meteorological (hurricanes, tornadoes)

Hydrological (floods, avalanches)

Factors affecting Hazord risk

Factors affecting hazard risk include the type and severity of the hazard, the exposure of people or assets to the hazard, and the vulnerability of those exposed.

plate tectonics theory

Scientific theory that Earth's outer shell is divided into plates that move and interact, causing earthquakes, volcanoes, and mountain formation.

plate margins

Plate margins are the boundaries where tectonic plates meet. There are three main types: divergent, convergent, and transform. These margins are dynamic areas where earthquakes, volcanic eruptions, and mountain formation can occur.

primary effects of earthquake

Primary effects of earthquakes are the immediate consequences, including ground shaking, surface rupture, and ground displacement.

secondary effect of a earthquake

Flashcard: Secondary effects of an earthquake are the indirect consequences such as landslides, tsunamis, fires, and liquefaction that occur as a result of the initial seismic event.

primary effect of a vocano

Primary effect of a volcano: Immediate consequences of an eruption, including ash fall, lava flows, pyroclastic flows, and volcanic gases.

secondary effect of a volcano

Flashcard: Secondary effect of a volcano - Refers to the consequences beyond the immediate eruption, such as lahars, pyroclastic flows, and ashfall, impacting the environment and communities.

immediate responses to volcanoes

Immediate responses to volcanoes include evacuations, providing shelter, distributing masks for ash, and monitoring air quality for health concerns.

long term responses to a volcano

Long term responses to a volcano involve rebuilding infrastructure, restoring ecosystems, and implementing monitoring systems for future eruptions.

evidence for climate change

Evidence for climate change includes rising global temperatures, shrinking ice sheets, declining Arctic sea ice, extreme weather events, and ocean acidification.

natural and human factors of climate change

Natural factors: Solar radiation, volcanic eruptions. Human factors: Greenhouse gas emissions, deforestation.

mitigation techniques for climate change

Flashcard: Mitigation techniques for climate change include reforestation, renewable energy, carbon capture, sustainable agriculture, and reducing greenhouse gas emissions.

adapation for climate change

Adaptation for climate change involves adjusting to its effects through strategies like building sea walls, implementing drought-resistant crops, and creating early warning systems.
