There s also a little bit of geography, take a look!

1.Similarities: both are located in the Eastern Hemisphere, mid-latitudes (the Tropic of Cancer crosses). Both land and sea are coastal countries.

Differences: India is located in the Northern Hemisphere; Australia is located in the Southern Hemisphere.

2.China's topography is high in the west and low in the east, and the flow direction of the large water system also flows from west to east with the topography. Because the high mountains in the west prevent the warm and humid air flow from the southeast from penetrating deep into the western interior, the rainfall is characterized by decreasing from east to west.

3.Hanjiang River, Xiangjiang River, Ganjiang River, Jialing River, Minjiang River, Yalong River; Taihu Lake, Poyang Lake, Dongting Lake.

4.The middle and upper reaches of the mountainous agricultural reclamation section, the forest cutting section, the overgrazing section, and the junction of the mountains and plains are the boundaries.

In other words, the middle and upper reaches of the Yangtze River, the Yangtze River is between Yibin City, Sichuan Province and Yichang City, Hubei Province, the middle reaches between Yichang and Jiangxi Province, and the lower reaches of the lake.

1. Similarities: The Tropic of Cancer has passed.

Differences: one is in the northern hemisphere, the other is in the southern hemisphere, 2, the west is high and the east is low from west to east in a cascade decrease, so that the source of the river is mostly in the western region, the river channel extends to the east, and the precipitation is mostly in the eastern coastal areas, and the west also causes some rainfall because of the rise of warm and humid air currents over the sea.

3, Jinsha River, Dongting Lake, Poyang Lake, Taihu Lake (the one that is about to reach the sea) 4, soil erosion is distributed in the upper reaches of the river, the Yangtze River is upstream between Yibin City, Sichuan Province and Yichang City, Hubei Province, between Yichang and Jiangxi Province, the middle reach, and the lake mouth is downstream.

This belongs to the curriculum of World Geography:

Seawater temperature: The temperature of seawater mainly depends on the comparative relationship of seawater heat budget, that is, it depends on the thermal balance of seawater.

Spatial and temporal distribution of seawater temperature.

1) The budget and balance of seawater heat.

2) Distribution of sea water temperature.

The horizontal distribution of surface seawater.

In the same acacia yard area, different seasons - high water temperature in summer, low water temperature in winter.

In the same season, the water temperature is high at low latitudes and low at high latitudes.

Same latitude, different sea areas – warm currents pass through the sea area with high water temperatures.

The cold snap passes through the sea area and the water temperature is low.

Vertical changes in sea temperature.

Since solar radiation first reaches the surface of the seawater, the temperature of the seawater varies with depth. From the surface layer to the deep layer, the water temperature gradually decreases, and the surface sea water changes very little, and the deep sea water below 1,000 meters often remains cold.

The regulating effect of seawater on atmospheric temperature.

The ocean has a large area, a large amount of water, and a large heat capacity, so the change in sea temperature is much smaller than that of land temperature. As a result, the temperature over the ocean changes more slowly than over the land, so the sea water plays a regulating role in atmospheric temperature.

Reason: Water flows from top to bottom, and objects with larger masses are difficult to carry while objects with smaller masses are easy to handle, for example, the mouth of the Yangtze River is clay, and the source is gravel. Thus the answer is b.

14、b

Find the intersection point by making a perpendicular line from the highest point of precipitation in the map to the dotted line (topographic profile). Then pass the elevation scale to the right of this point to make a perpendicular line, find the intersection point, and read the height of this point, which is the height of the place where the mountain slope has the most precipitation.

15. The maximum annual precipitation is about 150 mm, which should be a continental climate or a desert climate. Northeast Australia and southeastern Brazil have a tropical rainforest climate, and the East African highlands traversed by the equator have a savannah climate with more annual precipitation than that.

The dotted line can be seen as a "topographic profile", and the "0 km" in "Horizontal Distance" is based on the coordinate intersection of the perpendicular line and the horizon line of the "summit" (just move the altimeter on the right here!). ）。

The dotted line in the figure refers to the altitude, and the vertical line from the highest point corresponds to exactly 0 meters, so it refers to the highest peak, and then the horizontal distance to the south slope is the north slope.

This is the distance of the longitudinal plane from south to north.
