Question

How are volcanic fissures formed?

Answer 1

Volcanic fissures are formed when tectonic plates shift and release pressure, causing cracks or fractures to form in the Earth's crust. Magma from the mantle rises through these fissures, eventually reaching the surface and leading to volcanic eruptions. The magma may flow out as lava or explode into the air as ash and gases. Over time, repeated volcanic activity along these fissures can create volcanic ridges or chains of volcanic mountains.

Answer 2

Volcanic fissures are formed when the Earth's crust is under stress due to movements in the tectonic plates. This stress causes the crust to crack and create fissures through which magma from the mantle beneath the crust can rise to the surface, leading to volcanic eruptions. The magma forces its way through these fissures, resulting in lava flows, ash emissions, and other volcanic activities.
