Question

Select all of the answers that apply. Some rules to remember when reading topographic maps are _____. the elevations of contour lines must always be whole number multiples of the contour interval the thin line separating two different rock units is a contact line points inside a contour line are a higher elevation than the contour line strike-and-dip symbols indicate the degrees of tilt of rock strata

Answer 1

The correct answers are A) The elevations of contour lines must always be whole numer multiples of the contour interval. and C) Points inside a contour line are a higher elevation than the contour line. Hope this helps

Answer 2

Answer: Option (1), (2) and (4)

Explanation: In order to study a topographical map, one must keep in mind the following points-

• Contour lines are lines of equal elevation and they are always a whole number in which 0 (zero) represents the mean sea level.
• Two contour lines never intersect each other.
• A contact line can be defined as the transition line between the two distinctive rock layers.
• The dip and strike value given in the map, adjacent to the rock strata depicts that how much a bed is dipping and what is its strike direction.
• The circular area showing maximum elevation above the mean sea level represents the top of a hill, whereas, a circular area showing minimum elevation elevation below the mean sea level depicts a basin.
