Volcano erupt when molten rock called magma rises to the surface.

2 tháng 5 2020

why does a volcano erupt?

dịch :

(tại sao một ngọn núi lửa phun trào?)

Answer :

-Volcanoes erupt when molten rock called magma rises to the surface. Magma is formed when the earth's mantle melts.

Melting may happen where tectonic plates are pulling apart or where one plate is pushed down under another.

Magma is lighter than rock so rises towards the Earth's surface. As the magma rises, bubbles of gas form inside it.

Runny magma erupts through openings or vents in the earth's crust before flowing onto its surface as lava.

If magma is thick, gas bubbles cannot easily escape and pressure builds up as the magma rises.

When the pressure is too much an explosive eruption can happen, which can be dangerous and destructive.

Another way an eruption happens is when water underneath the surface interacts with hot magma and creates steam,

this can build up enough pressure to cause an explosion.

dịch :

(Núi lửa phun trào khi đá nóng chảy gọi là magma nổi lên mặt nước. Magma được hình thành khi lớp phủ của trái đất tan chảy.

Sự nóng chảy có thể xảy ra khi các mảng kiến ​​tạo bị tách ra hoặc khi một mảng bị đẩy xuống dưới một mảng khác.

Magma nhẹ hơn đá nên nổi lên trên bề mặt Trái đất. Khi magma tăng lên, bong bóng khí hình thành bên trong nó.

Run magma phun trào qua các khe hở hoặc lỗ thông hơi trong lớp vỏ trái đất trước khi chảy trên bề mặt của nó dưới dạng dung nham.

Nếu magma dày, bong bóng khí không thể dễ dàng thoát ra và áp lực tích tụ khi magma tăng lên.

Khi áp lực quá lớn, một vụ nổ có thể xảy ra, có thể gây nguy hiểm và phá hoại.

Một cách khác một vụ phun trào xảy ra là khi nước bên dưới bề mặt tương tác với magma nóng và tạo ra hơi nước,

điều này có thể tích tụ đủ áp lực để gây ra vụ nổ.)
