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

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

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.

Many archeologists and anthropologists disagree with dr. thorne's view.  thorne strongly believes that what many calls "homo erectus"  was in fact  homo sapiens,  and that they migrated out of africa almost 2 million years ago and dispersed throughout europe and asia. that's way different  from what scientists have always believed about the evolution of the species.
