High school is an important year, and it is important for everyone to take good care of it, and the next step is to provide you with the necessary knowledge of the second grade。
1 earthquake:
A devastating earthquake above level 5 would cause enormous loss of human life and property and would be the most dangerous of all natural disasters. The magnitude, intensity, factors and distribution patterns of earthquakes are understood. In particular, it should be made clear that there is only one magnitude of an earthquake, and the contours refer to connections at points of the same intensity。
Tectonic earthquakes are generally more destructive than volcanic earthquakes. Earthquakes occur mostly at the plate boundary, but not cyclically (e. G. In the pacific earthquake belt, taiwan has experienced more frequent earthquakes in recent years, either because it is in the asia-europe plate collision zone or because it is active in recent years). Accurate prediction of earthquakes remains the direction of all humankind's efforts。
2. Volcanoes:
Volcanic eruptions have had a devastating impact on the earth's ecological environment. Since the beginning of the twenty-first century, the global volcanic eruption has been high. Volcanic disasters have been accompanied by very fertile soil and abundant geothermal heat. Indonesia, located along the borders of the asia-europe plate with the pacific ocean and the indian ocean plate, is the most volcanic country in the world, with more than 70 active volcanoes, known as "volcanic nations"。
3. Mudflow:
Most of our mudslides occur in the western mountainous regions on the edge of the tibetan plateau, such as yunnan and the western sichuan provinces. This is due mainly to the fact that the terrain is dominated by mountains, frequent earthquakes leading to rock break-ups and severe weather conditions, dry and wet seasons and heavy rains, human destruction of vegetation and extensive engineering。
In the high school study cycle, it is important to learn more about the subjects, to learn the rules of the examinations and to learn about the regular examinations, thus helping to improve the scores. For your information, the author of yulu has compiled a knowledge point for 14th grade and 2nd grade。
