Study Notes
Natural Phenomena
- Natural phenomena are non-artificial (not man-made) states or processes perceptible through the senses, such as earthquakes, tsunamis, hurricanes, sunrise, and thunder.
- These occurrences can be perceived through senses like sight, hearing, and feeling.
- Examples of natural phenomena include the Nile River flooding, which was crucial for ancient Egyptian livelihood, and the river's shift in position over time.
Identifying Changes in Natural Phenomena
- Changes in natural phenomena can be identified using human senses, such as observing the sunrise or feeling the ground shake.
- Artificial sensors can also be used to detect changes in natural phenomena, including temperature, wind speed, acidity levels, and atmospheric pressure.
Sensors and Measurements
- Anemometers detect changes in wind speed, which can indicate if hurricanes are becoming more aggressive over time.
- Barometers measure atmospheric pressure, helping to gauge if a storm is coming.
- Turbidity sensors assess the clarity of fluids, such as water quality.
- Light sensors gauge the shift in the Sun's position relative to the Earth with the seasons, indicating changes in sunlight over time.
Review and Definitions
- Natural phenomena are non-artificial states or processes perceptible through the senses.
- Anemometer: detects changes in wind speed.
- Barometer: measures atmospheric pressure.
- Turbidity: the clarity of a fluid.
- Light sensors: gauge the shift in the Sun's position relative to the Earth with the seasons.
