Day, Night & Seasons: Rotation and Tilt — Practice · Grade 6 Science
Chapter: Earth, Moon, Sun & Space ModelsWhat this practice covers
By the end of Day, Night & Seasons: Rotation and Tilt you should be able to:
- I can explain why the angle of sunlight changes how much energy reaches each square metre.
- I can give two pieces of evidence that distance from the Sun does not cause the seasons.
- I can explain why summer days are longer as well as warmer.
8 questions, written answer and multiple choice, each with a worked explanation.
Vocabulary used: rotation, revolution, evidence, system boundary, uncertainty.
Problem 1
Answer and explanation
Earth’s rotation. One orbit is a different motion associated with the year.
Compare the scientific meaning and reasoning after an independent attempt. A different accurate supported response can be correct; human review is required.
Problem 2
Answer and explanation
That allows each hemisphere’s orientation toward sunlight to change during the orbit and creates the seasonal contrast.
Compare the scientific meaning and reasoning after an independent attempt. A different accurate supported response can be correct; human review is required.
Problem 3
Answer and explanation
Energy received per unit area decreases under this model, even though the total beam amount stays 100.
Compare the scientific meaning and reasoning after an independent attempt. A different accurate supported response can be correct; human review is required.
Problem 4
Answer and explanation
It challenges the claim that distance alone causes the familiar opposite seasons; orientation and day length provide a better explanation.
Compare the scientific meaning and reasoning after an independent attempt. A different accurate supported response can be correct; human review is required.
Problem 5
Answer and explanation
Summer gives 840 units per area per day and winter 350. Both longer daylight and the larger modeled received rate contribute. These illustrative values explain an energy mechanism, not a guaranteed daily temperature, and real clouds, surface properties, and seasonal response also matter.
Compare the scientific meaning and reasoning after an independent attempt. A different accurate supported response can be correct; human review is required.
Problem 6
Answer and explanation
No. Weather varies within seasons. The geometry concerns a broader illumination pattern, not a guarantee that every summer day is warm.
Compare the scientific meaning and reasoning after an independent attempt. A different accurate supported response can be correct; human review is required.
Problem 7
- rotation: A body turning about its axis.
- Day and night are caused by Earth completing an orbit each day.
- Opposite hemispheric seasons are explained by Earth–Sun distance alone.
- One illustrative result establishes every real condition and needs no further evidence.
Answer and explanation
rotation: A body turning about its axis.
A body turning about its axis. Summer gives 840 units per area per day and winter 350. Both longer daylight and the larger modeled received rate contribute. These illustrative values explain an energy mechanism, not a guaranteed daily temperature, and real clouds, surface properties, and seasonal response also matter.
Problem 8
- Day and night are caused by Earth completing an orbit each day.
- revolution: A body’s orbital movement around another body or system.
- Opposite hemispheric seasons are explained by Earth–Sun distance alone.
- One illustrative result establishes every real condition and needs no further evidence.
Answer and explanation
revolution: A body’s orbital movement around another body or system.
A body’s orbital movement around another body or system. Summer gives 840 units per area per day and winter 350. Both longer daylight and the larger modeled received rate contribute. These illustrative values explain an energy mechanism, not a guaranteed daily temperature, and real clouds, surface properties, and seasonal response also matter.
