Equal points of elevation on a topographic map are connected by contour lines.
a. true
b. false user: the height of an object above sea level is its relief.
a. true
b. false

The correct answers are:

1. a. True.

The contour lines are one of the most important methods for showing the relief on the maps. They are connecting dots that are on the same elevation, and they are closed areas. With this method, the observer of the map gets a very nice picture of the landscape that is presented, presuming the observer understand the contour lines.

2. b. False.

The height of an object above sea level is the elevation of the object. The level of the sea is taken as a zero height, and usually with the method of triangulation, or by using satellites, the elevation of a certain object is determined.
