A fissure
The answer is fault
VOLCANISM
A deep crack in the Earth's surface beginning with "ch" could refer to a chasm. A chasm is a deep, narrow opening in the earth, usually caused by geological processes like erosion or tectonic activity. Examples of famous chasms include the Grand Canyon and the Gorge du Verdon in France.
A deep crack in the earth's surface is called a fault.
It is called a volcano.

The East Africa Rift System
A vent is an opening through which gases or liquids can pass, such as in a volcano. A rift is a crack or fissure in the ground caused by earth movement or volcanic activity. Essentially, a vent is the opening, while a rift is the crack or fissure itself.
A natural opening where water can return to the surface is called a spring. Springs occur when groundwater flows up to the surface through an opening in the Earth's crust, such as a crack or fissure, due to pressure differences or geological formations. This allows the water to emerge on the land surface or into a body of water.
A light shining through a crack is called a beam of light. It can produce a visible streak or column of light that passes through the opening.
The answer is fault
Fault
"Crevice" is a noun that refers to a narrow opening or crack in a surface, typically in rock or ice. It can also be used more broadly to describe any narrow opening or fissure.
eruption
A vent is an opening in the Earth's surface where gas or magma can escape, while a rift is a crack or fissure in the Earth's crust where tectonic plates are pulling apart. Vents are typically associated with volcanic activity, while rifts are formed by the movement of tectonic plates.
