Chọn B Câu đề bài: Điều nào sau đây nói đúng về núi lửa hình thành tại điểm mà tại đó hai mảng kiến tạo phân kỳ?
Đáp án C: Dãy núi trung du Đại Tây dương là một ví dụ tiêu biểu
Các đáp án còn lại:
A. Hầu hết các núi lửa hình thành theo cách này
B. Học thuyết kiến tạo mảng không thể giải thích được
D. Chúng không bao gồm đá nóng chảy
Thông tin trong bài:
Volcanoes can also be created when two plates begin to diverge. Then, magmafram below the earth’s crust moves up to fill the void between the two plates. Large quantities of lava spill out fiom the void. Volcanoes of this type usually are found not on land. but on the ocean floor. In extreme instances this can lead to the formation of gigantic, sunken mountain ranges like Mid- Atlantic Ridge that spans nearly the entire length of the Atlantic Ocean.
Núi lửa cũng có thể được tạo ra khi hai mảng kiến tạo bắt đầu phân kì. Sau đó, magma từ bên dưới lớp vỏ trái đất di chuyển lên để lấp đầy khoảng trống giữa hai mảng. Một lượng lớn dung nham tràn ra từ khoảng trống. Các loại núi lửa thuộc loại này thường không được tìm thấy trên đất liền, mà ở thềm đại dương. Trong những trường hợp cùng cực, điều này có thể dẫn đến sự hình thành các dãy núi khổng lồ, trũng như Mid-Atlantic Ridge (dãy núi trung du Đại Tây dương) trải dài gần như toàn bộ chiều dài của Đại Tây Dương.
