Question

now that weve gotten the formal definitions in class, take a moment to make sure you know the following definitions
the point directly above you
celestial latitude
celestial longitude
the point directly below you
an imaginary sphere that extends around earth on which the stars appear to move
exactly half way between the celestial poles
an imaginary line that extends from the north celestial pole to the south celestial pole that passes through ...

Explanation:

To solve this matching problem, we recall the definitions of celestial terms:

1. "The point directly above you" → Zenith (the point in the sky directly overhead).
2. "celestial latitude" → Angular distance north or south of the celestial equator (analogous to Earth’s latitude).
3. "celestial longitude" → Angular distance east or west along the celestial equator (analogous to Earth’s longitude, also called right ascension in some contexts).
4. "the point directly below you" → Nadir (the point directly opposite the zenith, below your feet).
5. "An imaginary sphere that extends around Earth on which the stars appear to move" → Celestial Sphere (the conceptual sphere of stars surrounding Earth).
6. "exactly half way between the celestial poles" → Celestial Equator (midway between the north and south celestial poles, analogous to Earth’s equator).
7. "An imaginary line that extends from the north celestial pole to the south celestial pole that passes through..." → Celestial Meridian (a great circle on the celestial sphere passing through the poles and the zenith/nadir of a location).

If we assume the right - hand column (though not fully shown) contains terms like Zenith, Celestial Latitude, Celestial Longitude, Nadir, Celestial Sphere, Celestial Equator, Celestial Meridian, the matches are:

• "The point directly above you" ↔ Zenith
• "celestial latitude" ↔ (definition of celestial latitude)
• "celestial longitude" ↔ (definition of celestial longitude)
• "the point directly below you" ↔ Nadir
• "An imaginary sphere that extends around Earth on which the stars appear to move" ↔ Celestial Sphere
• "exactly half way between the celestial poles" ↔ Celestial Equator
• "An imaginary line that extends from the north celestial pole to the south celestial pole that passes through..." ↔ Celestial Meridian

Since the problem is about celestial (astronomical) definitions, the subfield of Natural Science (Astronomy, a sub - field of Physics or "Others" in the given Natural Science subfields) applies.

This is a matching problem about celestial terms. We use the definitions of celestial - related concepts: Zenith is the point directly above, Nadir is directly below, Celestial Sphere is the imaginary sphere with stars, Celestial Equator is midway between celestial poles, Celestial Meridian is the line between celestial poles, and celestial latitude/longitude are angular distances like Earth's latitude/longitude.

Answer:

1. "The point directly above you" - Zenith
2. "celestial latitude" - (angular distance north/south of celestial equator)
3. "celestial longitude" - (angular distance east/west along celestial equator)
4. "the point directly below you" - Nadir
5. "An imaginary sphere that extends around Earth on which the stars appear to move" - Celestial Sphere
6. "exactly half way between the celestial poles" - Celestial Equator
7. "An imaginary line that extends from the north celestial pole to the south celestial pole that passes through..." - Celestial Meridian
