Multiple Choice

Why does the sun appear to move across the sky over the course of a day?

• The sun moves in circles around the North Pole. When it is over your head, it's day. When it's not, it's night.

• Earth rotates on its axis

• The sun is falling due to gravity

• The gravitational pull of the planets in szygy

Poll

Did the sun “rise in the east and set in the west” on the day you observed?

• Yes

• No

the answer should be no. The sun rises somewhere between northeast and southeast and sets somewhere between northwest and southwest.

(except for days around September 21 or March 21)

Multiple Choice

Which day is longer?

• the one with the higher sun altitude

• The largest average azimuth taken over the course of several hours

• the one with the lower sun altitude?

• This day

Multiple Choice

How does the sun’s altitude at transit relate to the length of the day?

• The lower the altitude the longer the day

• The higher the azimuth the longer the day

• The higher the altitude the longer the day

• The lower the azimuth the longer the day

 The sun rises in the east, at 90° azimuth, and sets in the west, at 270° azimuth, at two times of year (around September 21 and March 21). More generally, the sun rises somewhere between northeast and southeast and sets somewhere between northwest and southwest.

Multiple Choice

How do the sun’s rising and setting positions relate to the length of the day? (Assume northern hemisphere)

• The farther north the rising and setting positions, the shorter the day

• The farther east/west the rising and setting positions, the longer the day

• The farther north the rising and setting positions, the longer the day

• The farther east/west the rising and setting positions, the shorterthe day

Multiple Choice

The Earth's motion around its axis

• Revolve

• Rotate

• 1 Earth year

• twirl

Multiple Choice

As a planet rotates, which moves more—

• point at the pole

• point at the equator

• point directly under the sun

• point at the magnetic north/south pole

Multiple Choice

If the sun rises north of east, then where does the sun set?

• South of West

• West

• North of West

• East of West

Multiple Choice

If the sun rises north of east, then where would the sun be at midday?

• Directly overhead

• overhead and a little South

• overhead and a little North

• Along the Prime Meridian

Multiple Choice

If the sun rises north of east, then what time of year is it?

• March

• September

• March or September

• June

Multiple Choice

Sunrise and sunset points move along the horizon throughout the year.

• True

• False

Multiple Choice

Why did we use the pins on the tennis balls?

• To understand how Earth’s rotation causes the movements of the sun over the

  course of a day

• To explore the daily path of the sun and how it varies over the course of a year

• To contemplate and synthesize all we've learned throughout the

  Exploration

• To explore how the sun appears to move across the sky over the course of a day.

How does the position of the sun in the sky change throughout the day and throughout the year?
