Question

1. which land feature is shown by v - shaped contour lines pointing upstream?

a. plateau
b. slope
c. hill
d. valley

Explanation:

To determine the land feature with V - shaped contour lines pointing upstream, we analyze each option:

• Option a: A plateau is a flat - topped elevated area, and its contour lines are usually more like concentric or parallel lines representing flatness, not V - shaped pointing upstream.
• Option b: A slope is a general term for an inclined surface. The contour lines on a slope are more evenly spaced and do not have a characteristic V - shape pointing upstream.
• Option c: A hill has contour lines that are concentric (forming circles or ovals) around the peak, representing the elevation increase towards the top, not V - shaped pointing upstream.
• Option d: In a valley, especially a river valley, the contour lines form a V - shape. The V - shape points upstream because the river (which erodes the valley) flows downstream, and the contour lines follow the shape of the valley, with the open part of the V facing downstream and the tip pointing upstream.

Answer:

d. Valley
