Question
Three other factors also influence seasonality:
- Axial ti: Earth’s axis tis 23.5 degrees
from the plane of the ecliptic, or the imaginary plane line that joins the centers of the Sun and Earth. Because of this ti, one hemisphere is inclined towards the Sun, while the other is tied away from it. The hemisphere tied towards the Sun receives its direct, vertical rays, resuing in longer days than nights due to more intense insolation, or exposure to sunlight. In the hemisphere where the axis is tied away, the reverse is true. Therefore, axial ti determines the duration and intensity of insolation on Earth in the two hemispheres.
The figure in the activity shows the Northern Hemisphere tied towards the Sun, with the Sun’s rays (yellow arrows) directly striking the Tropic of Cancer. Note that the circle of illumination at different latitudes, which indicates the length of day and night at those latitudes. If the circle of illumination cuts a latitude in such a way that the lighted portion is greater than the dark portion, days are longer than nights. When the darkened portion is greater, the reverse is true.
Given these conditions, identify the effects of the three factors discussed above.
Drag the labels to their appropriate targets, placing the descriptions of insolation in the pink targets and all other descriptions in the blue targets.
