Question

which of the following is a way in which remote sensing helps in predicting natural hazards? measuring changes in the physical properties of earths surface, sending warning messages to people in affected areas, monitoring social media for reports of hazards, issuing evacuation orders to at - risk populations

Explanation:

Remote sensing uses sensors to detect and classify objects on Earth from a distance. By measuring changes in the physical properties of Earth's surface (like temperature, elevation, vegetation cover etc.), it can identify precursors to natural - hazards such as land - slides, floods, and volcanic eruptions. Sending warning messages, monitoring social media, and issuing evacuation orders are not functions of remote sensing itself.

Answer:

measuring changes in the physical properties of Earth's surface
