Indicate if the geographic coordinates below are lines of latitude (mark all that apply)

a. n 34 08' 44.9"

b. s 18 09' 30.3"

c. e 10 25' 41.3"

d. w 118 07' 02.3"

latitudes that are (a)  and (b)

longitudes that are  (c) and (d)

Explanation:

we get here line of latitudes that are

for

(a)  N 34 08' 44.9"

it is north  34 degree 8 minute 44.9 seconds

it is Northern Hemisphere

and

(b) S 18 09' 30.3"

it is south 18 degree 9 mint 30.3 seconds

it is Southern Hemisphere

and

here

(c) E 10 25' 41.3" and ( d) W 118 07' 02.3"

they are not at line of latitude

they are at line of longitude because east and west

as we know that N and S  are at Latitudes

and E and W  are at longitudes

a characteristic is a deep cut in the earth or left over rock aka till.
