“What causes bloody noses?”
It's cold and dry where we are, and my daughter has a runny nose. Recently though, there's been blood in her snot. What can cause this?

Irritation of the nasal mucosa due to low humidity with result in frequent nose blowing and increased vascularity and friability of the nasal mucosa. A humidifier or frequent saline spray will help. You may also apply Vaseline ointment inside the nose to decrease the friability of the mucosa.
Dryness definitely causes nose bleeds. Inflamed nasal passages are also a cause (seen a lot with allergies). A cool mist humidifier and saline nose drops at night help prevent them.
The nasal passages can get irritated and bleed especially if you are using heat and her nose is drying out. Use saline mist several times a day in her nose. Avoid aspirin or motrin. These can also make her nose bleed.
