  • What do you see at a continent-continent convergent plate boundary?
    ::你看到大陆-大陆- 大陆- 大陆- 大陆- 共聚板块边界了吗?

    Big mountains! The best place to see two continental  plates  converging is in the Himalaya  Mountains . These mountains are the highest above  sea level  on Earth. They are very popular with mountain climbers.
    ::大山!看到两块大陆板块汇合的最好地方是喜马拉雅山。 这些山脉是地球上海平面上最高的山,非常受登山者欢迎。

    Continent-Continent Convergence
    ::大陆 -- -- 大陆汇合

    Another type of  convergent plate boundary  is when two continental plates collide. Continental  lithosphere  is low in density and very thick. Continental lithosphere cannot subduct. So when two continental plates collide, they just smash together. This is just like what happens if you put your hands on two sides of a sheet of paper and bring your hands together. The material has nowhere to go but up ( Figure   )!   and metamorphic   result from the tremendous forces of the collision. But the  crust  is too thick for  magma  to get through. As a result, there are no   at continent- continent  collision zones.
    ::另一种趋同的板块边界是两块大陆板块相撞时。 大陆平地密度低, 密度大, 厚度大。 大陆平地无法潜入。 所以当两块大陆板块相撞时, 它们就相撞在一起。 这就像把你的手放在一张纸的两边, 并把你的手放在一块纸上一样。 材料无处可去, 只有图( figure ) ! 以及碰撞的巨大力量所产生的变形结果。 但是地壳太厚, 岩浆无法穿透。 结果, 大陆大陆大陆大陆的相撞区没有这样的区域 。

    Tectonic plates colliding to form mountains in continent-continent convergence.
     
    When two plates of continental crust collide, the material pushes upward. This forms a high mountain range. The remnants of subducted oceanic crust remain beneath the continental convergence zone.

    Mountain Building
    ::山区山区建设

    Continent-continent convergence creates some of the world’s largest mountains ranges. The Himalayas ( Figure   ) are the world's tallest mountains. They are forming as two continents collide. The Appalachian Mountains are the remnants of a larger mountain range. This range formed from continent-continent collisions in the time of Pangaea.
    ::大陆和大陆的汇合创造了世界上最大的山脉。 喜马拉雅山脉(图 ) 是世界上最高的山脉。 喜马拉雅山脉(图 ) 正在形成两大大陆相撞。 阿帕拉契亚山脉是更大山脉的残存。 这一山脉由潘加亚时大陆和大陆之间的碰撞形成。

    The Karakoram Range is part of the Himalaya Mountains. K2, pictured here, is over 20,000 feet high. The number of mountains this tall in the Himalayas is impressive.

    Summary
    ::摘要

    • Continental crust is too buoyant to subduct.
      ::大陆地壳的浮力太大,无法俯冲
    • When two continental plates converge, they smash together and create mountains.
      ::当两块大陆板块交汇时,它们相撞相撞,形成山脉。
    • The amazing Himalaya Mountains are the result of this type of convergent plate boundary.
      ::惊人的喜马拉雅山 是这种交汇板块边界的结果
    • The Appalachian Mountains resulted from ancient convergence when Pangaea came together.
      ::阿巴拉契亚山脉是潘加亚聚在一起时古老的汇合形成的。
