n.软流层；（地）软流圈；岩流圈

The asthenosphere is a layer of the Earth's mantle that is capable of flowing like a fluid.
这层软流层是地幔中能够像液体一样流动的一层。
The movement of tectonic plates occurs within the asthenosphere.
板块运动发生在软流层内。
Melted rock from the asthenosphere can rise to form magma chambers.
软流层中的熔岩可以上升形成岩浆室。
Seismic waves travel faster through the rigid lithosphere than through the ductile asthenosphere.
地震波在坚硬的地壳中比在柔性的软流层中传播得更快。
The asthenosphere plays a crucial role in plate tectonics and continental drift.
软流层在板块构造和大陆漂移中起着关键作用。
Volcanoes often form at boundaries where the asthenosphere is being forced upwards by tectonic forces.
火山常常在地壳板块相互挤压、迫使软流层向上涌动的边界处形成。
The asthenosphere has a lower viscosity compared to the upper mantle, allowing it to flow more easily.
与上地幔相比，软流层的粘度较低，因此更容易流动。
Some theories suggest that the asthenosphere may be partially molten, contributing to mantle convection.
一些理论认为软流层可能是部分熔融的，这有助于地幔对流。
The temperature and pressure conditions in the asthenosphere facilitate the movement of rocks and minerals.
软流层内的温度和压力条件有利于岩石和矿物的移动。
Understanding the properties of the asthenosphere helps geologists predict volcanic eruptions and earthquakes.
理解软流层的性质有助于地质学家预测火山喷发和地震。
