1. which location is closest to the prime meridian?

a. perth
b. ayers rock
c. melbourne
d. sydney

1. which location is closest to the equator?

a. perth
b. ayers rock
c. melbourne
d. sydney

1. look at the map of australia. what is the latitude and longitude of ayers rock?

a. 35°s 131°e
b. 25°s 131°e
c. 25°s 129 °e
d. 35°n 131°w

Explanation:

1. Since the two points have the same latitude (35 degrees North), they can be distinguished by their longitude. Elevation is not relevant for map - coordinates distinction in this context, and they already have the same latitude. Map projection is about representing the 3D Earth on a 2D surface and not for distinguishing points with the same latitude.
2. The Prime Meridian is at 0° longitude. Among the given locations in Australia, Perth has the smallest longitude value (around 115°E), so it is closest to the Prime Meridian compared to the others.
3. The Equator is at 0° latitude. Among the given locations, Ayers Rock is at a lower latitude (around 25°S) compared to Perth (around 32°S), Melbourne (around 38°S), and Sydney (around 34°S), so it is closest to the Equator.
4. By looking at the map of Australia, Ayers Rock is located at approximately 25°S latitude and 131°E longitude.

Answer:

1. c. by their longitude
2. a. Perth
3. b. Ayers Rock
4. b. 25°S 131°E
