Geography — Understanding Natural Hazards + 5 more topics

Natural hazards are essentially natural processes that pose a threat to human life, property, and the environment. It's important to distinguish between a hazard and a disaster. A hazard is the potential threat, while a disaster occurs when that threat actually causes significant damage and disruption that a community can't handle on its own.

Earth's outermost layer, the lithosphere, is made up of the crust and the rigid upper part of the mantle. This lithosphere isn't a single, continuous layer; it's broken into several large and many smaller pieces called tectonic plates. These plates "float" on the semi-fluid asthenosphere, which is part of the upper mantle, and are driven by convection currents within the mantle.
