Question:
If you lived on Mars and observed the solar system from there, _____________ would describe retrograde loops, ______________ would always be seen near the sun, and _________________ would never be visible as crescent phases
Answer:
1. All other planets
2. Mercury, Venus, and Earth
3. Jupiter and Saturn
Explanation:
Living on Mars, all other planets would describe the retrograde loops, while the inner planets (Mercury, Venus, and Earth
) would always be seen near the sun. Planets like the Jupiter and Saturn which are far away from the sun will never have a crescent phase as those that will have a crescent phase must be between the mars and the sun
Answer:
Parallax would be most effective in measuring distances to stars which are close to the Earth.
Explanation:
In the experiment,
- The parallax shift would decrease as the pencil would move further away from the scientist's eye, so option 1 would be invalid.
- the size of the pencil remains constant, so option 2 would be invalid.
- the parallax shift can be observed when the pencil has objects in the background to provide relation, that is to say, the shift of the pencil when seen relative to background objects; therefore, if we assume that the pencil is a star nearby to the Earth, and the background objects are stars that are further away, then the shift of, and thus, distance to the nearby star can be easily observed.
A subduction zone is also generated when twooceanic plates collide — the older plate is forced under the younger one — and it leads to the formation of chains of volcanic islands known as island arcs.
