The opening that you are asking about is called a vent. Magma can burst through any weakness in the side of a Volcano or underground passage where Magma is close to the surface.
There are also openings called Tubes that are sometimes formed that Magma flows through that are like channels and the Lava stays very hot and flows very fast through them to the end where it comes out very fluid.

Magma rises through the crust due to differences in density between the magma and surrounding rock. Magma is less dense than the solid surrounding rock, so it moves upwards through cracks and fractures in the crust. As it rises, magma can also be driven by pressure differences and heat from the Earth's mantle.
Magma gets pushed through a vent due to the build-up of pressure beneath the Earth's surface. As the magma rises, it creates fractures in the rocks above, eventually reaching the surface through the vent. This process is driven by the buoyancy of the magma and the force of gas expansion within it.
fissure
A hot spot is an area where magma from deep within the mantle rises through the crust in the middle of a tectonic plate, creating volcanic activity and forming a chain of volcanic islands or seamounts. The Hawaiian Islands are a well-known example of hot spot activity.
fissure
the magma gets to hot it bursts under the sea forming island
To unlock Crevice Cave, you have to get through Blizzard Island, which you unlock after talking to Mr. Mime. That's true. There are 20F in Blizzard Island, first 10F in Crevice Cave, and second 4F in Crevice Cave.
Gas passes through small crevices of your anus until it is actually released into the environment, expanding each crevice for the passage. After the gas has passed the crevice, the crevice closes creating minuscule vibrations. The more dramatic the crevice opens and closes, the louder the sound emitted.
A geyser is formed when a spring is geothermally heated to the point that the water bursts through the surface in an upward stream of water and water vapor. The eruption is caused by superheated water that has been heated by magma beneath the earth's surface.
"Crevice" is a noun.
Get through Blizzard Island
Incorrect. A crevice is a narrow opening or crack in a structure, such as a wall, whereas a keyhole is a small hole designed for inserting a key.
volcanoes erupt because of the pressure of the magma pressing against the volcano until eventually it bursts out of it becoming lava.
There was a worm in the crevice.
To look slyly, or with the eyes half closed, or through a crevice; to peep.
crevice is English, hendedura is Spanish
