What is a Mudslide also known as?

  1. Landslide

  2. Earthquake

  3. Mudflow

  4. Avalanche

The correct answer is: Mudflow

A Mudslide and a Mudflow are actually two different types of natural disasters. A Mudslide is when a section of unstable earth slides down a slope. This can also be known as a Landslide. A Mudflow, on the other hand, is when a large amount of mud and debris flows downhill at a fast speed. This is caused by heavy rainfall or a sudden release of water. Therefore, while a Mudslide may also be known as a Landslide, the correct term for this type of natural disaster is a Mudflow. Options A, B, and D are incorrect as they are terms for different types of natural disasters.
