Contour Maps and Landforms – Solutions
Q.1. Answer the following questions.
(1) How can the distribution of the height and landforms in a region be shown?
Answer: The distribution of height and landforms in a region can be shown using contour maps, which represent altitude, relief, slope, and direction of slope using contour lines.
(2) To whom are the contour maps useful?
Answer: Contour maps are useful for mountaineers, trekkers, soldiers, defense officers, and planners as they help in understanding landforms and planning routes or construction.
(3) What do you understand by observing contour lines?
Answer: By observing contour lines, one can understand the altitude, slope, and shape of landforms. Contour lines that are closer together indicate steep slopes, while those that are farther apart indicate gentle slopes.
(4) How will a contour map be useful for a farmer?
Answer: A contour map can be useful for a farmer as it helps in understanding the terrain, planning irrigation systems, preventing soil erosion, and deciding the best areas for farming based on land slope and water flow.
Q.2. Fill the blanks with appropriate words.
- If the contour lines are closer to each other, the slope is steep.
- The contour lines on the map represent places with the same altitude.
- The slope can be understood from the distance between the contour lines.
- If the distance between two contour lines is more, the slope is gentle.
