Read the material and answer the following questions. (26 points) Material-Huashan Mountain is one of the famous five mountains in China, bordering the magnanimous Weihe Plain in the north and the Qinling Mountains in the south, with an altitude of 1000 meters.

(1) The strata in Qinling Mountains are rising, while the strata in Weihe Plain are relatively declining.

(2) Duan Lushan. Huashan Mountain is located at the northern foot of Qinling Mountains, with relatively uplifted rock mass and a large cliff on its northern slope.

(3) The shaping of surface morphology is the result of the combined action of internal force and external force. Internal forces caused the Weihe Plain to collapse, forming valleys (lowlands). External forces (wind, running water, etc.). ) fill it with sediment and form a fertile plain.

(1) From the map, this area is a fault, and the displacement of the fault is mainly in the vertical direction. The relatively descending rock mass forms valleys or lowlands, and the relatively ascending rock mass develops into mountains or highlands.

(2) According to the first material, Huashan Mountain is located on the northern slope of Qinling Mountain, which is a fault-block mountain.

(3) Analyze the interaction between internal force and external force.
