ANS:D - all the above.

The rainfall at any place may be determined by all the above: its intensity, direction, and frequency.

• Intensity: Refers to the amount of rainfall that occurs over a specific period, usually measured in millimeters per hour or inches per hour. Intensity indicates how heavy or light the rainfall is at a particular moment.
• Direction: Refers to the path or trajectory of rainfall as it moves across the landscape. Understanding the direction of rainfall helps in predicting its movement and potential impact on surrounding areas, such as flooding or erosion.
• Frequency: Refers to how often rainfall events occur over a given period, such as daily, monthly, or yearly. Frequency data is essential for analyzing rainfall patterns and trends, which helps in long-term planning and risk assessment related to water resources management, agriculture, and infrastructure development.
