The Effect of Water Model

Refined petroleum products are derived from crude oils through processes such as catalytic cracking and fractional distillation. Gasoline / Kerosene / Lubricant / Asphalt / Aviation Oil / Diesel / Paraffin

Model Size:45*23*11cm This model is mainly used to teach the seabed terrain under the cover of deep sea water in geography teaching. It is difficult for students to observe and understand its shape and structure. Through the seabed model, the students realized that the edge of the continental land terrane was slowly slanting down the edge of the continental shelf in a plain plain called the continental shelf, and the seabed slanted down to form a continental slope. The continental shelf and the continental slope form a whole, closely adjacent to the edge of the continent, and are an extension of the continent. The bottom of the continental slope is the real boundary between the mainland and the ocean. At this boundary, the crust has huge cracks due to different geological structures, and a series of trenches appear. The ocean floor is the main body of the ocean, where the long seabed is distributed. The mountains are also called ridges. There is a high ridge in the oceans, which are twisted and twisted, but connected to each other and through the four oceans, collectively known as the mid-ocean ridge. On both sides of each mid-ocean ridge there is a vast closed or semi-enclosed area of ​​the vast basin. There are also individual or stripped volcanic islands (chains) in the ocean.
