Even if you didn't know these were cities of the US, how could you tell from the temperature curves that they were all in the northern hemisphere?

To determine if cities are located in the northern hemisphere based on temperature curves, you can follow these steps:

1. Obtain data: First, gather temperature data for the cities in question. This information could be obtained from weather websites, climate databases, or even plotted temperature graphs over time.

2. Understand seasons: Familiarize yourself with the seasons in the northern and southern hemispheres. Note that the seasons occur at opposite times in each hemisphere due to the tilt of the Earth's axis.

3. Analyze temperature trends: Review the temperature curves for each city, paying attention to the patterns over time. Look for fluctuations that correspond to different seasons.

4. Compare temperature changes: Compare the timing and magnitude of temperature changes between cities. For example, if one city experiences winter conditions from December to February while another city demonstrates warmer temperatures during the same period, it indicates that these cities are in different hemispheres.

5. Identify distinct patterns: Look for consistent temperature patterns that align with the typical seasons of the northern hemisphere, such as colder temperatures during months like December, January, and February, and warmer temperatures during June, July, and August.

6. Corroborate with additional factors: If available, consider other factors that can confirm the hemisphere, such as vegetation, local climate patterns, or geographical location.

By analyzing temperature curves for different cities and comparing them to the known seasonal patterns of the northern hemisphere, you can determine if the cities are likely located in the northern hemisphere even without prior knowledge about their specific locations.

To determine if the cities are in the northern hemisphere based on temperature curves, follow these steps:

Step 1: Obtain temperature data for each city: Retrieve temperature data for each city under consideration.

Step 2: Plot temperature curves: Plot the temperature curves for each city on a graph, with time (months or years) on the x-axis and temperature on the y-axis.

Step 3: Analyze the behavior of temperature curves: Look for patterns and trends in the temperature curves. Pay attention to the seasonal variations and how temperatures change throughout the year.

Step 4: Identify seasonal patterns: Notice if the temperature curves exhibit typical seasonal patterns. In the northern hemisphere, cities generally experience colder temperatures in winter (December, January, February) and warmer temperatures in summer (June, July, August).

Step 5: Compare peaks and troughs: Compare the timing of the lowest and highest temperatures in each city's curve. If the coldest temperatures occur in the months associated with winter (December to February) and the warmest temperatures occur in the months associated with summer (June to August), it suggests that the city is located in the northern hemisphere.

Step 6: Consider other factors: Keep in mind that temperature alone might not be enough to conclusively determine if a city is in the northern hemisphere. There are other factors to consider, such as daylight hours, prevailing wind patterns, and the geographical location of the city.

By analyzing the seasonal patterns and comparing the timing of temperature peaks and troughs, you can determine if the cities are located in the northern hemisphere, irrespective of whether you knew their actual locations.
