Question

1. the phoenix mars lander landed on may 25, 2008 at 68°n latitude on mars. the tilt of mars axis of rotation is approximately 25 degrees. days on mars (called sols) are 24 hours, 37 minutes, 22 seconds.

the data table below shows information for arctic village, alaska, which is located at 68°n latitude on earth.
construct an explanation to support the claim that the pattern of seasonal variations and the length of daylight hours at the phoenix lander site on mars and at arctic village, alaska, are similar. include both factors in your explanation.

Explanation:

The tilt of a planet's axis causes seasonal variations. Mars has a tilt of approximately 25 degrees, similar to Earth's tilt of about 23.5 degrees. This tilt leads to changes in the angle and duration of sunlight received at different times of the year. For the length of daylight hours, in both locations (Mars' 68°N and Arctic Village, Alaska which is also at a high latitude), as the planet (Earth or Mars) orbits its star (Sun), the high - latitude regions experience periods of longer daylight (like the 24 - hour daylight in Arctic Village in July and August, which would be analogous to a similar period on Mars) and shorter daylight as the tilt causes the hemisphere to be more or less exposed to the star's light over the orbital period.

Answer:

The tilt of Mars' axis (≈25 degrees, similar to Earth's ≈23.5 - degree tilt) causes seasonal variations as in Earth. For daylight hours, high - latitude locations (like 68°N on Mars and Arctic Village, Alaska) show similar patterns of longer (e.g., 24 - hour daylight in Arctic Village summer, analogous to a Martian'summer' at 68°N) and shorter daylight due to the planet's orbital position and axial tilt affecting the exposure to the star's light.
