Seasons and the Earth Tilt — Free MYP2 Sciences Practice Questions
1QuestionClimatic Differences Due to Earth MovementConcept Practice
3 marks~5 minCriterion A
The graph shows average monthly temperatures for City X (latitude 0°) and City Y (latitude 45°N). City X has a temperature range of about 2°C; City Y has a range of about 25°C.
a
Identify the angle of Earth's axial tilt. [1]
b
Explain why City X has a small temperature range throughout the year. [1]
c
Compare how Earth's axial tilt affects the temperature range in City X and City Y differently. [1]
Solutions
2QuestionEffect of Tilt and Orbit on Day LengthAssessment Practice
3 marks~5 minCriterion D
A student in Reykjavik, Iceland (64°N) is designing a solar-powered streetlight. She records these times:
| June — sunrise | 03:00 | sunset: 23:00 |
|---|---|---|
| December — sunrise | 11:00 | sunset: 15:30 |
a
Calculate the day length, in hours, for June and for December. [1]
b
Explain how the difference in day length affects the amount of time the solar panel has to charge the battery. [1]
c
Compare the battery storage needed in June with that needed in December, and state one assumption the student must make about weather conditions. [1]
Solutions
3QuestionEarth Rotation and RevolutionAssessment Practice
4 marks~6 minCriterion B
A student measures the length of a shadow cast by the same stick at noon each day in a Northern Hemisphere city over four months.
| Month | January | February | March | April |
|---|---|---|---|---|
| Shadow length (cm) | 45 | 30 | 20 | 15 |
a
Describe the trend in shadow length from January to April. [1]
b
Explain how Earth's revolution around the Sun causes the Sun to appear higher in the sky from January to April, and how this affects shadow length. [2]
c
The student predicts the shadow length for May will be approximately 15 cm. Compare this prediction with the pattern shown in the data and explain whether you agree. [1]
Solutions
4QuestionWhy We Have SeasonsAssessment Practice
5 marks~8 minCriterion C
A student places a 1-metre stick in the ground and measures its noon shadow on the first day of each month.
A classmate claims seasons are caused by Earth's changing distance from the Sun.
| Month | Jan | Feb | Mar | Apr | May | Jun | Jul | Aug | Sep | Oct | Nov | Dec |
|---|---|---|---|---|---|---|---|---|---|---|---|---|
| Shadow length (cm) | 85 | 70 | 55 | 40 | 30 | 28 | 32 | 40 | 55 | 70 | 85 | 95 |
A classmate claims seasons are caused by Earth's changing distance from the Sun.
a
Identify the months in which the classmate's claim predicts the longest and shortest shadows. [1]
b
Explain why the data contradicts the distance-based claim. Use two specific values from the table. [2]
c
Compare the shadow lengths in June and December and explain how Earth's axial tilt — the lean of Earth's axis — accounts for the difference. [2]
