地幔对流如何驱动板块运动，学界目前对驱动机制仍有何争论？
How does mantle convection drive plate motion, and what debates remain about the mechanism?
地幔因内部放射性衰变与残余热产生密度差，形成缓慢的对流环，把上方岩石圈板块带着移动。争议在于到底是地幔拖曳、洋脊推力还是板块俯冲时的重力滑沉占主导。图尔科特与舒伯特的《地球动力学》用黏性流体模型量化了这些力的相对贡献。
The mantle's internal heat from radioactive decay and residual warmth creates density differences that drive slow convection cells, carrying the overlying lithospheric plates. A debate persists over whether mantle drag, ridge push, or the slab pull of subducting plates dominates. Turcotte and Schubert's Geodynamics quantifies the relative contributions of these forces with viscous-fluid models.

山脉为什么不会一直长高，最后会被什么拉回平衡？
Why don't mountains keep growing taller, and what pulls them back to balance?
抬升让山体变高、重力变大，而风化、河流切割和山体自身重量造成的地壳下沉（均衡调整）会抵消抬升；当侵蚀削低的速度赶上升高速度，山脉高度就趋于稳定。
Uplift raises peaks and increases gravity, while weathering, river cutting, and isostatic sinking under the mass counter it; when erosion keeps pace with uplift, mountain height stabilizes.

驱动板块运动的力主要来自哪里？目前认为哪种力最为重要？
What forces drive plate motion, and which is currently thought to dominate?
板块运动的驱动力主要包括地幔对流（热物质上升、冷物质下沉）、洋脊推挤（ridge push）和板块俯冲时的板片拖曳（slab pull）。多数地球动力学研究认为，高密度冷板片下沉产生的板片拖曳是其中最主要的驱动力。
Plate motion is driven mainly by mantle convection (rising hot and sinking cold material), ridge push at mid-ocean ridges, and slab pull as dense, cooling plates sink at subduction zones. Most geodynamic studies conclude that slab pull—the downward pull of a sinking dense plate—is the dominant force.

什么是震间的“库仑应力转移”？请以北安纳托利亚断裂1939年以来的强震序列加以说明。
What is Coulomb stress transfer between earthquakes? Illustrate it with the sequence of strong shocks on Turkey's North Anatolian Fault since 1939.
大地震的同震位错把构造应力重新分配到邻近断层上：被加载的断层段更接近破裂，被卸载的则趋于平静，这就是库仑应力转移。计算表明，北安纳托利亚断裂自1939年起十余次强震自东向西渐进发生，多数落在先前事件造成的应力增益区内，显示断层间存在系统性相互作用，可用于中长期地震危险性评估。
In a large earthquake, coseismic slip redistributes tectonic stress onto neighbouring faults: loaded segments are driven closer to failure while unloaded ones quiet down — this is Coulomb stress transfer. Calculations show that more than ten strong earthquakes on the North Anatolian Fault since 1939 progressed westward step by step, most falling within stress-increase lobes left by earlier events, revealing systematic fault interaction that informs medium-term seismic hazard assessment.

圣安德烈斯断层属于哪种板块边界，为什么它地震频发？
What kind of plate boundary is the San Andreas Fault, and why is it so earthquake-prone?
圣安德烈斯断层是太平洋板块与北美板块之间的转换边界，两盘水平错动而不新生或消减地壳。由于断层带并非完美平直，应力在弯曲处长期积累，一旦超过摩擦强度便突然释放引发地震。华莱士等人对该断层的滑动历史做了系统编录。
The San Andreas Fault is a transform boundary between the Pacific and North American plates, where blocks slide past each other without creating or destroying crust. Because the fault is not perfectly straight, stress builds up at bends and releases suddenly as earthquakes when friction is exceeded. Wallace and colleagues cataloged its slip history in detail.

威尔逊旋回描述大洋盆地从张开、扩张、俯冲到最终闭合，并可能重新开启的反复过程。它把大陆裂解、漂移、碰撞造山串联成一个循环，适用于盘古超大陆的聚合与裂解。威尔逊在1966年提出这一框架，统一了之前零散的板块运动观察。
The Wilson cycle describes the cyclic opening, spreading, subduction, and eventual closure of ocean basins, which may then reopen again. It links continental rifting, drift, and collisional mountain-building into one loop, as seen in the assembly and breakup of Pangaea. Wilson proposed the framework in 1966, unifying earlier fragmentary observations of plate motions.

Seafloor spreading is the process where new oceanic crust forms at mid-ocean ridges from upwelling mantle material and is pushed outward on both sides. It explains why ocean crust is relatively young and provides a mechanism for continental drift.

俯冲带是什么，它如何塑造大陆边缘和火山弧？
What is a subduction zone, and how does it shape continental margins and volcanic arcs?
俯冲带是密度较大的大洋板块在海沟处俯冲到另一板块之下的边界，携带的水降低地幔楔熔点，诱发弧岩浆作用。沿美洲西岸的安第斯型陆缘便是大洋板块俯冲到大陆板块之下形成的火山弧。这类边界也是地球上最强地震与海啸的主要发生地。
A subduction zone is a boundary where a denser oceanic plate dives beneath another plate at a trench, and the water it carries lowers the melting point of the overlying mantle wedge, triggering arc magmatism. The Andean margin of South America is an example where oceanic lithosphere subducts under continental crust to form a volcanic arc. These boundaries also generate the planet's largest earthquakes and tsunamis.

洋中脊是如何形成新海洋地壳的？
How do mid-ocean ridges create new oceanic crust?
洋中脊是张裂型板块边界，地幔物质在此上涌减压熔融，岩浆侵入并喷发形成玄武岩质新生地壳。新地壳随海底扩张向两侧推移，并在冷却中记录下地磁场的极性反转，形成对称的磁条带。麦克唐纳在1986年系统描述了洋中脊的构造与热液活动。
Mid-ocean ridges are divergent boundaries where upwelling mantle melts by decompression, and magma intrudes and erupts to form fresh basaltic crust. New crust is carried sideways by seafloor spreading and, as it cools, records magnetic reversals as symmetric stripes. Macdonald described the ridge's tectonics and hydrothermal activity in detail in 1986.

魏格纳指出，南美洲东岸与非洲西岸的海岸线能像拼图一样吻合，且两洲在地层、古生物（如已灭绝的中龙）和古气候（如冰川遗迹）上高度对应。他在1912年提出、1915年于《海陆的起源》中系统阐述这一假说，为后来的板块构造学说奠定了基础。
Wegener noted that the coasts of South America and Africa fit together like puzzle pieces, and that the two continents share matching rock strata, fossils (such as the extinct reptile Mesosaurus), and ancient climate evidence (such as glacial deposits). He proposed the idea in 1912 and developed it in his 1915 book 'The Origin of Continents and Oceans,' laying groundwork for later plate tectonics.

斑岩型铜矿几乎只出现在俯冲带上方的岩浆弧中,而SEDEX型铅锌矿却产出于裂谷盆地序列,这种构造专属性由什么决定?
Porphyry copper deposits occur almost exclusively in magmatic arcs above subduction zones, whereas SEDEX lead-zinc deposits sit within rift-basin successions—what dictates this tectonic specificity?
俯冲板片脱水产生的流体交代地幔楔,将铜、钼带入浅位酸性岩浆房;岩浆出溶的含盐流体随后在斑岩体顶部裂隙网中沉淀金属,故矿床沿大陆边缘弧成带展布。SEDEX矿床则源于裂谷伸展:同生断裂把富金属热卤水排入海底卤水池,硫化物与盆地沉积物同层沉淀,因而局限于被动边缘或弧后盆地的层序之中。
Fluids liberated by the dehydrating slab metasomatize the mantle wedge, ferrying copper and molybdenum into shallow felsic chambers; saline magmatic fluids exsolved there then precipitate metals in fracture stockworks atop the porphyry intrusions, aligning deposits as belts along convergent margins. SEDEX ores instead reflect extension: growth faults vent metalliferous brines into seafloor brine pools where sulfides settle syntemporaneously with basin fill, confining them to passive-margin or back-arc sequences.

河流纵剖面如何记录地壳抬升？什么是“裂点”，它能透露哪些断层活动信息？
How does a river's longitudinal profile record crustal uplift? What are knickpoints, and what do they reveal about fault activity?
在地表持续抬升的地区，河流必须向下切割才能保持通向基准面的通道，河床坡度随岩石抬升速率调整，纵剖面呈上凸形，其陡度指数与抬升速率正相关。断层错动会让河床出现陡坎，即裂点；随后裂点如同一道侵蚀波向上游迁移，在下游遗留下低坡度的阶地。测定裂点与阶地的高度和位置，便可推算断层活动的时间与垂直断距。
Where the land rises steadily, a river must cut down to keep its route to base level, so the bed gradient adjusts to the rock-uplift rate and the profile turns convex, its steepness index tracking uplift. Fault movement oversteepens the bed into a knickpoint, which then sweeps upstream like a wave of erosion, stranding gentle terraces downstream. Measuring the heights and positions of knickpoints and terraces lets us date fault movements and estimate their vertical throw.

海底岩石像磁带一样左右对称地记录磁场反转?这条证据怎么坐实了大陆漂移?
Seafloor rocks record magnetic flips like tape, symmetrically striped — how did this clinch continental drift?
岩浆冷却时,其中的磁性矿物会沿当时地磁方向定向排列并冻结。1963年瓦因与马修斯指出:若洋中脊不断喷出新岩浆并把两侧老海底对称推向远方,反复发生的地磁南北倒转就会把海底磁化成以脊为轴、左右镜像的正负条带。几年后海上磁力仪剖面证实了这种斑马纹,由条带宽度推算的扩张速率又与陆上熔岩放射性测年标定的地磁年代表吻合——海底扩张由假说变为测量事实,大陆漂移由此获得动力机制,板块构造就此奠基。
When lava cools, its magnetic minerals freeze aligned with the ambient geomagnetic field. In 1963 Vine and Matthews proposed that if mid-ocean ridges keep erupting new crust and convey older seafloor symmetrically outward, recurring geomagnetic reversals would stripe the seafloor into mirror-image normal and reversed bands centered on the ridge. Ship-towed magnetometer profiles soon mapped those zebra stripes, and spreading rates computed from stripe widths matched the geomagnetic polarity timescale calibrated by radiometric dating of land lavas — seafloor spreading became measurement, continental drift gained its mechanism, and plate tectonics was born.

海底扩张指新的洋壳在大洋中脊处由地幔物质上涌冷凝形成，并逐年向两侧推开，老洋壳则在俯冲带重新沉入地幔。这一理论由哈里·赫斯（Harry Hess）在1962年的《大洋盆地的历史》中系统提出，为大陆漂移提供了关键机制。
Seafloor spreading is the process by which new oceanic crust forms at mid-ocean ridges from upwelling mantle material and is pushed outward over time, while older crust is consumed at subduction zones. Harry Hess proposed the concept in his 1962 paper 'History of Ocean Basins,' providing the mechanism that made continental drift plausible.

三种边界分别是：分离型（张裂，板块相互远离，常形成洋中脊）、汇聚型（碰撞或俯冲，板块相互挤压）和转换型（平行错动，如圣安德烈斯断层）。不同类型的边界对应着不同的地质活动，如地震、火山和山脉的形成。
The three types are divergent boundaries (plates pull apart, often forming mid-ocean ridges), convergent boundaries (plates collide or one subducts beneath another), and transform boundaries (plates slide past each other horizontally, such as the San Andreas Fault). Each type produces distinct geologic activity such as earthquakes, volcanoes, or mountain building.

什么是板块？
What are tectonic plates?
板块是地球岩石圈被分割成的大块坚硬岩板，浮在塑性流动的上地幔软流圈之上。它们缓慢移动，塑造着大陆、海洋和山脉的分布。
Tectonic plates are the large, rigid slabs into which Earth's lithosphere is broken; they float on the slowly flowing asthenosphere beneath. Their slow motion shapes the distribution of continents, oceans, and mountains.

大洋地壳和大陆地壳在成分、密度和厚度上有什么主要差别？
How do oceanic and continental crust differ in composition, density, and thickness?
大洋地壳以玄武岩为主，密度较大（约2.9–3.0 g/cm³）、较薄（约7公里），且年龄普遍较年轻。大陆地壳以花岗岩类岩石为主，密度较小（约2.7 g/cm³）、较厚（约30–50公里），并可保存数十亿年的古老岩石。
Oceanic crust is mostly basaltic, denser (about 2.9–3.0 g/cm³), thinner (about 7 km), and geologically young. Continental crust is richer in granitic rocks, less dense (about 2.7 g/cm³), thicker (about 30–50 km), and can preserve rocks billions of years old.

什么是“环太平洋火环”（Ring of Fire）？
What is the 'Ring of Fire'?
环太平洋火环是环绕太平洋边缘的一条带状区域，集中了大量板块边界，因此火山和地震极为频繁。美国地质调查局指出，地球上约75%的活火山和约90%的地震都发生在这一区域。
The Ring of Fire is a horseshoe-shaped belt around the edges of the Pacific Ocean where many plate boundaries meet, making volcanoes and earthquakes extremely frequent. The USGS notes that about 75% of the world's active volcanoes and about 90% of its earthquakes occur there.
