Temperature is measured using thermometers, either mercury-based or digital. It changes throughout the day—usually lowest in the early morning and highest in the afternoon. Seasonal changes affect temperature too, with higher readings in summer and lower in winter, depending on sunlight and location.

Temperature is measured with thermometers, which may be traditional (using mercury or alcohol) or digital. It fluctuates daily—typically coldest just before sunrise and warmest in the early afternoon. Over seasons, it varies due to Earth’s tilt and orbit: summers are hot, winters are cold. Factors like altitude, cloud cover, and wind also affect it. Maximum and minimum thermometers help record temperature ranges, which are used in statistics and forecasts to understand weather patterns over time.
