17
Q

Landforms Called deltas that form where rivers flow into other bodies of water such as a sea

A

Deposition

18

Layers of sediment forming at the bottom of the ocean

A

Deposition

19
Q

A

Deposition

20
Q

A

Deposition

21
Q

Two dimensional model of the earths surface

A

Topographic map

22
Q

It connects points of egalitarian elevation

A

Contour line

23
Q

The difference between high and low elevations

24
Q

Difference in elevation between each line

A

Contour interval

25
Usually every fifth line is printed darker and has the elevation printed on it
Index contour
26
Rules for contour
Lines don't cross Contours form closed loops Contours bend upstream Elevation for a hill is less then 1 of what the next contour should be
27
Steeper slopes =
Closer lines
28
Gradual slopes=
Farther apart lines
29
Shows the exact elevation and is noted
