Learn: Hazards

Welcome!Today we'll explore hazards as part of the Geography 8035 GCSE (AQA) curriculum. This topic focuses on natural and human-created risks to people and the environment.

What are Natural Hazards?A natural hazard is a physical event that poses a risk to people, property, or the environment. Examples include earthquakes, floods, and tropical storms. Hazards can be worsened by human activities like deforestation or poor planning.

Factors Affecting Hazard RiskThe risk of a hazard depends on several factors. These include population density, location, and the ability to prepare and respond. For example, areas near plate boundaries are at higher risk of tectonic hazards.

Tectonic HazardsTectonic hazards are caused by movements of the Earth's plates. These include earthquakes, volcanoes, and tsunamis. Plate margins (boundaries) are key locations for these hazards.

Immediate and Long-Term ResponsesAfter a hazard occurs, responses are crucial. Immediate responses include search and rescue, while long-term responses involve rebuilding and improving infrastructure to reduce future risks.

Weather HazardsWeather hazards are extreme weather events, such as tropical storms or floods. Tropical storms form over warm ocean waters where temperatures exceed 27°C.

Climate Change and HazardsClimate change is increasing the frequency and intensity of some hazards, such as floods and tropical storms. Human activities like burning fossil fuels contribute to these changes.

Review Time!Great work! You've learned about hazards, their types, and factors affecting risk. Let's test your understanding with a few questions.
