Seek to solve geographical problems. thank you

This is a relatively open reasoning topic, which makes sense and can achieve the key points.

(1) This question is incredibly expensive at 8 points. It seems that there are at least four points to be answered.

Gu Liya ice core is located at the pass of West Kunlun Mountain, and its water source is ocean, which has nothing to do with inland water cycle or is very small.

When seawater evaporates, it preferentially evaporates and agglutinates oxygen 18, which makes the actual oxygen 18 have a low specific gravity in the atmosphere.

During the transportation of water vapor to Guria Glacier, precipitation is formed due to topographic uplift or other factors, and oxygen 18 preferentially condenses to form rainwater, and the specific gravity is further reduced.

The Guriya ice core is far away from the ocean, so the oxygen 18 that finally reaches the Guriya ice core to form precipitation is very rare.

(2) (This title is 4 points, which seems to discuss the difference between spring, summer and winter. Considering that it is close to the inland desert, so ...)

In spring and summer, in China and Central Asia, the surface snow is dissolved and exposed, and the chances of sand blowing and even sandstorms increase, which corresponds to the high ice content in spring and summer.

In winter, the local surrounding surface is covered with snow, or because of the freezing of low temperature soil, the chance of sand blowing or sandstorm is reduced, which corresponds to low content in winter.

(3) This question is a bit strange, because there are at least four points to answer, and I don't know which one not to answer. ...

Obviously, Guria Glacier is located at a higher altitude, which means that the average temperature is low, the main body of the glacier is complete, and there is little ice shortage, so the continuity of time is guaranteed.

Located in an arid area, the temperature changes greatly, which means that the oxygen changes greatly.

Glaciers have a considerable scale and thickness, and the amount of data that can be studied is large and sufficient.

Because it is located at high altitude and deep in the plateau, there is less human interference.

(4) This question should be a 2+4 structure. There are two points in the second quiz.

The difference between the two: the amplitude of the Guria ice core is larger.

Reason:

The Guria ice core is located in the mountainous plateau area, with high altitude and large contact area with the atmosphere. The Greenland ice core is located in a relatively gentle place, with a relatively low altitude and a small contact surface. In contrast, the Guria ice core is more sensitive to atmospheric changes.

The Guriya ice core is located in the inland arid area, but it is low, so the temperature changes relatively greatly, and the corresponding oxygen isotope 18 has a high amplitude. The time and thickness of surface snow in winter and summer are also obviously different, which is equivalent to amplifying the effect of temperature change. However, Greenland is located at a high latitude, and the temperature changes relatively little, so the corresponding surface characteristics do not change obviously.
