Mudslide happens when too much water turn the earth into mud and push the mud down a hillside.
Mudslide is a disaster.
Mudslide can destroy lots and lots of houses as in Bolivia.
On 6 December 2008, lots of people died because of landslides and mudslides in Bukit Antarabangsa, Kuala Lumpur, Malaysia.
Mudslide always happens when people cut down trees and plants on hills because:
The root of the trees can hold the soil on the hills; so when people cut down the trees, there will be nothing to hold the soil during heavy rain.
- The roots of the trees drink the water from the ground to help the trees grow, so there will not be too much water under the ground.
- Animals living around the trees can help drinking the water too, and the earthworms’ tunnel can help the water to travel deep into the ground.
