With reference to climate change phenomena, consider the following statements:

Glacial lake outburst floods (GLOFs) are primarily caused by heavy rainfall.

Snowmelt-induced floods occur when temperatures rise and accelerate snowmelt.

GLOFs are limited to high-altitude regions and do not pose a threat to lowland areas.

How many of the above statements are correct?

Question

Glacial lake outburst floods (GLOFs) are primarily caused by heavy rainfall: This is incorrect. GLOFs are caused by the overflow or breach of glacial lakes, often due to melting glaciers or landslides.
Snowmelt-induced floods occur when temperatures rise and accelerate snowmelt: This is correct. Rising temperatures lead to faster snowmelt, increasing river discharge.
GLOFs are limited to high-altitude regions and do not pose a threat to lowland areas. Incorrect: GLOFs can occur in any region where glacial lakes are present, and the impact of GLOFs can be felt downstream, including lowland areas.
