Question

activity c extreme seasons
question: what are seasons like at the poles and equator?
1 collect data select the earth tab. fill in the data for the north pole on june 21 and december 21 (to measure the sun ray angle, select show protractor)

date	rays on panel	temp. (°c)	daylight hours	sun ray angle
june 21
december 21

2 analyze what do you notice about the seasons on the north pole?
3 collect data click on the space tab, and drag the person to the equator (latitude 0°) select the earth tab and fill in the data table for this location

date	rays on panel	temp. (°c)	daylight hours	sun ray angle
june 21
december 21

4 analyze what do you notice about the seasons on the equator?
5 draw conclusions describe what june 21 and december 21 would be like on the north pole and the equator.

Explanation:

At the North Pole, on June 21 (summer - solstice in the Northern Hemisphere), there is 24 - hour daylight (mid - summer), with the Sun remaining above the horizon, and the Sun ray angle is relatively high for the pole. On December 21 (winter - solstice in the Northern Hemisphere), there is 24 - hour darkness (mid - winter), with the Sun never rising. The poles have extreme seasonal differences with long periods of continuous daylight or darkness. At the equator, on both June 21 and December 21, there are approximately 12 hours of daylight. The Sun ray angle is relatively high throughout the year, resulting in relatively consistent and warm temperatures, with little seasonal variation in terms of daylight hours and temperature.

Answer:

1. For North Pole data collection (approximate values):

• June 21: Rays on panel - high (compared to winter), Temp. (-10 - 0°C), Daylight hours - 24, Sun ray angle - around 23.5° (angle of Earth's tilt).
• December 21: Rays on panel - low, Temp. (-30 - - 40°C), Daylight hours - 0, Sun ray angle - 0°.
• Analysis: The North Pole has long periods of continuous daylight or darkness. In summer (June 21), it is in a state of constant sunlight, and in winter (December 21), it is in constant darkness. Temperatures vary greatly between summer and winter.

1. For equator data collection (approximate values):

• June 21: Rays on panel - high, Temp. (25 - 30°C), Daylight hours - 12, Sun ray angle - around 66.5 - 90° (varies depending on the exact time of day).
• December 21: Rays on panel - high, Temp. (25 - 30°C), Daylight hours - 12, Sun ray angle - around 66.5 - 90° (varies depending on the exact time of day).
• Analysis: The equator has relatively consistent daylight hours (around 12 hours) throughout the year and relatively stable and warm temperatures.

1. Conclusions: On June 21 at the North Pole, it is the height of summer with 24 - hour daylight and relatively warmer temperatures for the pole. At the equator, it is a normal day with around 12 hours of daylight and warm temperatures. On December 21 at the North Pole, it is the depth of winter with 24 - hour darkness and very cold temperatures. At the equator, it is again a day with around 12 hours of daylight and warm temperatures, showing little seasonal change compared to the poles.
