PLEASE I NEED HELP WILL MARK BRAINLIEST The location of two hikers is marked on the topographic map to the right as points F and H. What is the elevation of the camper at point F? (first picture)

Each hiker climbed to point G along the path indicated by the arrow. What was the change in elevation for the hiker that took the steepest path to point G?

The Vs just below the path of F up to G indicates what landform? (pic 2)

Use the satellite images above for Questions 4 and 5

4. What is the purpose of this series of satellite images?

To show the path of three different rivers
The direction the water flows in the river
The changes in the path of the river

5. Weathering (breaking off sediments upriver), erosion (moving the sediments down river) and finally deposition caused the changes in the river.

What helps hold sediments in place to prevent erosion?
