Physical features are those like relief features like mountain, plateau and plains.
Explanation:
- When your teacher says physical features she means the features that are found on the surface of the earth like features present on land and water.
- Physical features found on a plane can be represented by different topographies depending upon the location of that feature on earth like the case of mountains they categories of certain physical features like valleys lakes, cirques, horns, and other erosional and depositional features.
- When on a plateau or tableland which is itself a feature produced by the process of erosion and earth's formation other being hills and mounds of all sizes, the plains are flat landscape which has low or high elevated areas from mean sea levels.
- Over e oceans or water bodies, these features can found at various depths and may be shown by areas of the high and low density of water.
- Thus an atlas records all the above physical features on a map of the earth.
The unit of measure used to determine an absolute location on a map or globe is called "degrees" of longitude and latitude.
