It is generally harder to make a fire in wet conditions, such as rain, as moisture can dampen the materials needed to start a fire. In snowy conditions, you can still make a fire using dry wood beneath the snow or by creating a platform to keep the fire off the wet ground.
The three things needed to make a fire burn, what is called the Fire Triangle, are 1] oxygen 2] heat 3] fuel
Heat fuel and oxygen
Because fuel is a FLAMMABLE material.

Wildfires mainly occur in very dry areas with lots of trees. The trees keep the fire going. Dry conditions also make it harder to contain since there's no moisture nearby to try and smother the fire with. High winds are also a factor and make it even more harder to try and contain the fire
To make a fire, you need three main things: fuel, heat, and oxygen. Fuel can be anything that burns, like wood or paper. Heat is necessary to ignite the fuel and start the fire. Oxygen is needed to sustain the combustion process.
If you remove one of the three things needed to make a fire (fuel, heat, or oxygen), the fire will not be able to sustain itself and will go out. These components work together in a fire triangle to create and maintain a flame.
Because more oxygen is needed for fuel for fire.
To build a fire, you need fuel (such as wood or paper), heat (from a match or lighter), and oxygen (from the air) to sustain combustion. These three elements work together to create and maintain a fire.
The term "fire triangle", or combustion triangle, refers to the inherent principles in the methodology of making a fire. The "fire triangle" is a model for understanding the resources and methods needed to make a fire.
