The Himalaya were formed when two plates of the earth’s crust, the Eurasian and Indo-Australian plates, collided. This forced the earth’s crust to be pushed up into mountains.

Hypothermia:

Hypothermia is a medical condition triggered when the core body temperature (that of the internal organs) passes below a certain threshold. The function of the patient’s muscles and the brain are then affected. Hypothermia can be triggered by dehydration, exhaustion, wetness, cold temperatures and inadequate clothing. There are several stages in the deterioration of the body into a hypothermic state. Symptoms of the condition can include a loss of coordination, violent shaking, irrationality and a loss of balance. If untreated, hypothermia can result in death. However, it can be treated quickly by ensuring the patient is warm, dry, fed and hydrated.
