Question

if a topographic map has closely spaced contour lines, what does this indicate about the terrain?○ the terrain is relatively flat○ the area has no elevation changes○ the terrain has a steep slope○ the area is below sea levelquestion 22 ptswhat is the minimum number of satellites required for a gps receiver to determine its location on earths surface?○ one satellite○ four satellites○ three satellites○ two satellites

Explanation:

For the first question: Contour lines on a topographic map represent equal elevation. Closely spaced lines mean elevation changes rapidly over a short distance, which defines a steep slope.
For the second question: GPS uses trilateration; to determine a 3D position (latitude, longitude, altitude) on Earth's surface, a minimum of 4 satellites are required to account for clock errors in the receiver and calculate the full position.

Answer:

1. The terrain has a steep slope
2. Four satellites
