Mars (axis tilt = 25.2°)

Is Polaris a circumpolar star in Miami 's sky? Choose the correct explanation. Polaris is not circumpolar because it rises and sets in Miami 's sky. Polaris is circumpolar because it never rises or sets in Miami 's sky. Polaris is circumpolar because it rises in Miami 's sky. Polaris is not circumpolar because it is not visible in Miami 's sky.

Polaris is circumpolar because it never rises or sets in Miami 's sky.

Where does the north (or south) celestial pole appear in your sky? The north celestial pole appears in Miami 's sky at an altitude of 40 ∘ in the direction due north. The north celestial pole appears in Miami 's sky at an altitude of 32 ∘ in the direction due north. The north celestial pole appears in Miami 's sky at an altitude of 26 ∘ in the direction due north. The north celestial pole appears in Miami 's sky at an altitude of 70 ∘ in the direction due north.

The north celestial pole appears in Miami 's sky at an altitude of 26 ∘ in the direction due north.

Which of the following best describes why we have seasons on Earth? The tilt of Earth's axis causes different portions of Earth to receive more or less direct sunlight at different times of year. The varying speed of Earth in its orbit around the Sun gives us summer when we are moving fastest and winter when we are moving slowest. The tilt of Earth's axis causes the Northern Hemisphere to be closer to the Sun than the Southern Hemisphere in summer, and visa versa in winter. Earth's elliptical orbit means we are closer to the Sun and therefore receive more intense sunlight at some times of year than at others.

The tilt of Earth's axis causes different portions of Earth to receive more or less direct sunlight at different times of year.

what is the cause of the seasons? Earth's speed varies in its orbit around the Sun, giving us summer when Earth is moving fastest and winter when Earth is moving slowest. The tilt of Earth's axis causes different portions of the Earth to receive more or less direct sunlight at different times of year. The seasons are caused by variation in the amount of rainfall (or snowfall) in different places at different times of year. The tilt of Earth's axis causes the Northern Hemisphere to be closer to the Sun than the Southern Hemisphere in summer, and vice versa in winter.

The tilt of Earth's axis causes different portions of the Earth to receive more or less direct sunlight at different times of year.

which statement best describes how variation in the Earth-Sun distance affects the seasons? The variation in Earth-Sun distance over the course of each year has virtually no effect on the seasons. No matter where you live or what the seasons, it is generally hotter when Earth is closer to the Sun and colder when Earth is farther from the Sun. Summer occurs when Earth is closer to the Sun and winter occurs when Earth is farther from the Sun.

The variation in Earth-Sun distance over the course of each year has virtually no effect on the seasons.

Which of the following planets should have the most extreme seasons? Neptune (axis tilt = 29.6°) Mars (axis tilt = 25.2°) Jupiter (axis tilt = 3.1°) Uranus (axis tilt = 97.9°)

Uranus (axis tilt = 97.9°)

why is it generally hotter in summer than in winter? Check all that apply. We have more hours of daylight in summer. Earth rotates more rapidly in summer. The Sun is higher in the sky in summer. We are closer to the Sun in the summer.

We have more hours of daylight in summer. The Sun is higher in the sky in summer.

If we have a new moon today, when we will have the next full moon? in about 1 week in about 2 weeks in about a month in about 6 months

in about 2 weeks

Two stars that are in the same constellation: must both be part of the same cluster of stars in space. must both have been discovered at about the same time. may actually be very far away from each other.

may actually be very far away from each other.

In winter, Earth's axis points toward the star Polaris. In spring: the axis also points toward Polaris. the axis points toward Vega. the axis points toward the Sun.

the axis also points toward Polaris.

A week after full moon, the Moon's phase is: first quarter. third quarter. new.

third quarter.

Beijing and Philadelphia have about the same latitude but very different longitudes. Therefore, tonight's night sky in these two places: will look about the same. will have completely different sets of constellations. will have partially different sets of constellations.

will look about the same.

winter.

The North Celestial Pole is 35.0 ∘ above your northern horizon. This tells you that: you are at latitude 35.0 ∘ N. you are at longitude 35.0 ∘ E. it is the winter solstice.

you are at latitude 35.0 ∘ N.
