Final answer:
Orographic precipitation occurs in the Cordillera of BC, caused by moist air ascending over the mountain range, cooling, and condensing to form precipitation.
Step-by-step explanation:
The type of precipitation that is present in the Cordillera in BC is orographic precipitation. Orographic precipitation occurs when moist air is forced to ascend over a mountain range, such as the coastal mountains of British Columbia. As the air rises, it cools and condenses, forming clouds and precipitation. This process is particularly common on the western slopes of these mountains, where the moist air from the Pacific Ocean is lifted, leading to high levels of precipitation typical of the region. In the case of the Cordillera in BC, it is the Rocky Mountains that cause the orographic precipitation.
This type of precipitation is common in mountainous regions and can result in heavy rainfall or snowfall on one side of the mountains, while the other side experiences drier conditions, known as the rain shadow effect.
