The flow of the Chang Jiang is some 20 times greater than that of the
Huang He. As much of 40% of China's total grain production, 70% of rice
output, and more than 40% of the population are associated with the
Chang Jiang's vast basin that includes more than 3,000 tributaries. With
its numerous tributaries, the Chang Jiang drains nearly 20% of China's
total area. Its upper reaches tap the uplands of the Tibetan Plateau
before sweeping across the enormous and agriculturally productive
Sichuan Basin that supports nearly 10% of China's total population. It
is in the middle course of the Chang Jiang that the controversial Three
Gorges Dam is being constructed.
Earthquakes occur along plat boundaries and faults. Most earthquakes happen along the edge of continental and oceanic plates. Faults are found in the middle of the plates. They're like cracks that form when the different parts of the plates don't move in the same direction.
A rugged area with large variations in elevation would have high relief, whereas a relatively flat location would have low relief.
Maps that capture data approximately alleviation are termed topographic maps. Maximum geologic maps include topographic information inside the form of contour strains.
Comfort is the distinction between lowest and highest elevation in a location. Only a few surfaces on the earth are genuinely flat. We describe deviations from flatness as relief.
Similarly to showing absolute elevation, contour strains, by means of their spacing, monitor the steepness of slopes at a look. On a steep slope, they have got close collectively.

Answer:
slope should be <em>positive </em>0.5
Explanation:
Perpendicular lines have opposite slopes
The mountainous regions could not develop agriculturally as much as fields
