How Volcanoes Erupt

Indonesian is situated in the ring of fire that extends from Nusa Tenggaras, Bali, Java and ends in Atlantic ocean. Like other countries in circus-pacific belt, Indonesian has many volcanoes and the country records several volcanic eruptions her year. Do you know how volcanoes erupt? Hot temperature within the earth melts rocks. The molten rock becomes a flowing substance with thick consistency known as magma. As magma is lighter than solid rocks, it rises and creates magma chambers. The chamber also contains bubbles of gas. Sometimes, magma runs to the surface through vents. This runny magma is called lava. But when mama is too thick, it traps gas bubbles that creates pressure within the chamber. Too much pressure can cause an explosive eruption. This type of volcanic eruption is destructive and dangerous. Explosive- type volcanoes can blast hot clouds that destroy anything in their way. The hot clouds come with grey, powdery snow known as tephra that falls back to earth. The ash is dangerous for humans, animals, and plants but it also becomes natural fertilizer.

A. Hot temperature inside the earth melts rocks.
B. Magma that runs to the surface is called hot clouds.
C. Volcanoes have magma chamber created from molten rocks.

Opsi-opsi jawaban adalah pernyataan yang benar menurut teks kecuali opsi B.
Opsi B menyatakan:
Magma that runs to the surface is called hot clouds.
(Magma yang mengalir ke permukaan disebut awan panas.)

Perhatikan kalimat-kalimat pada baris 11-13 pada teks di atas:
Sometimes, magma runs to the surface through vents. This runny magma is called lava.
(Kadang-kadang, magma mengalir ke permukaan melalui lubang angin. Magma yang mengalir ini disebut lava.)
