At midnight the temperature is \( -6^{\circ} \mathrm{C} \). At midday the temperature is \( 9^{\circ} \mathrm{C} \). By hov much did the temperature rise?

The temperature at midnight is \( -6^{\circ} \mathrm{C} \) and at midday it is \( 9^{\circ} \mathrm{C} \). To find the temperature rise, you subtract the midnight temperature from the midday temperature: \[ 9^{\circ} \mathrm{C} - (-6^{\circ} \mathrm{C}) = 9^{\circ} \mathrm{C} + 6^{\circ} \mathrm{C} = 15^{\circ} \mathrm{C} \] So the temperature rose by \( 15^{\circ} \mathrm{C} \). Did you know that temperature fluctuations like this can significantly impact local weather patterns? For example, a rapid increase in temperature during the day can lead to the development of thunderstorms in certain climates. It's amazing how interconnected temperature changes and weather events are! For those who love to dive deeper into weather phenomena, you might want to check out meteorological resources that explain temperature anomalies. Understanding these concepts can enrich your knowledge about climate change and its effects on our environment, adding a layer of real-world significance to those numbers!
