The statement is true; magma from beneath Earth's surface can erupt through an opening in the crust called a vent, leading to various geological formations such as mountains and plains.
True or false: Magma on Earth's surface erupts through an opening in the crust called a vent. The statement is true. Magma, which is the molten rock beneath the Earth's crust, can reach the surface through openings known as vents. While not all magma reaches the surface, when it does, it is often through a vent associated with volcanic activity.
These vents can lead to the formation of mountains, plains, or other geological features depending on how the lava flows and cools. For example, rapid lava flow from long cracks can form lava plains, while upwelling lava that doesn't reach the surface may cause bulges in the crust and can contribute to the formation of mountain ranges like the Sierra Nevada. Volcanic eruptions like the one from Cleveland Volcano, visible as a plume of ash, show the dramatic nature of these geological events.
The vent is indeed the correct geological term for the opening through which magma is expelled onto Earth's surface during a volcanic eruption.
