Question

Определи истинность или ложность положений теории литосферных плит. Согласен(на) ли ты, что...Литосфера разделена на крупные и мелкие литосферные плиты, которые плавают по поверхности пластичной астеносферы.Граница между плитами проходит по срединно-океаническим хребтам и глубоководным желобам, а на материках – по крупным равнинам.Основной причиной движения литосферных плит является конвекционный поток в мантии.90% поверхности Земли приходится на крупные литосферные плиты.Литосферные плиты движутся по вертикали друг к другу в горизонтальном направлении. Альфред Вегенер выдвинул гипотезу о «дрейфе континентов».помогите пожалуйста ​

The Theory of Plate Tectonics

The theory of plate tectonics is a widely accepted scientific theory that explains the movement and interaction of the Earth's lithospheric plates. The theory states that the Earth's lithosphere is divided into several large and small plates that float on the semi-fluid asthenosphere. These plates are in constant motion, and their movement is responsible for various geological phenomena such as earthquakes, volcanic activity, and the formation of mountain ranges.

Evaluating the Statements

Let's evaluate the statements you provided one by one:

1. The lithosphere is divided into large and small lithospheric plates that float on the plastic asthenosphere. - This statement is true. The lithosphere is divided into several large and small plates that float on the semi-fluid asthenosphere [[1]].

2. The boundaries between the plates are located along mid-oceanic ridges and deep-sea trenches, and on continents, they coincide with major plains. - This statement is true. The boundaries between the plates are indeed located along mid-oceanic ridges and deep-sea trenches. On continents, they can coincide with major plains or other geological features [[2]].

3. The main cause of plate movement is the convective flow in the mantle. - This statement is true. The main driving force behind plate tectonics is the convective flow in the Earth's mantle. Heat from the Earth's core causes convection currents in the mantle, which in turn cause the movement of the lithospheric plates [[3]].

4. 90% of the Earth's surface is covered by large lithospheric plates. - This statement is false. The Earth's surface is not covered by large lithospheric plates to the extent of 90%. The exact percentage of the Earth's surface covered by lithospheric plates is not specified in the search results.

5. Lithospheric plates move vertically towards each other in a horizontal direction. - This statement is partially true. Lithospheric plates can move towards each other in a horizontal direction, but the movement is not purely vertical. The movement can involve various types of plate boundaries, such as convergent, divergent, and transform boundaries, where plates can move towards, away from, or slide past each other [[4]].

6. Alfred Wegener proposed the hypothesis of "continental drift." - This statement is true. Alfred Wegener was a German scientist who proposed the hypothesis of "continental drift" in the early 20th century. He suggested that the continents were once joined together in a supercontinent called Pangaea and have since moved apart [[5]].

Conclusion

In conclusion, the theory of plate tectonics is widely accepted in the scientific community. It explains the movement and interaction of the Earth's lithospheric plates, which are divided into large and small plates that float on the semi-fluid asthenosphere. The movement of these plates is primarily driven by the convective flow in the Earth's mantle. While some of the statements you provided are true, others are either partially true or false. It's important to rely on scientific evidence and ongoing research to understand the complexities of plate tectonics.
