Question

ocean floor
______ 11. process of collecting data about earth from far above earth’s surface
______ 12. indicates elevation on a topographic map

Explanation:

Question 11

The process of collecting data about Earth from far above its surface is remote sensing. Remote sensing uses satellites, aircraft, etc., to gather information about Earth's surface, atmosphere, etc., without direct physical contact.

On a topographic map, contour lines (or contour intervals) indicate elevation. Contour lines are lines connecting points of equal elevation, and the contour interval is the vertical distance between adjacent contour lines, helping to show the elevation changes on the map.

Answer:

Remote Sensing
