Why does heavy rainfall trigger landslides in many landscapes with steep slopes?

Heavy rain fall is rainfall more than 100mm in 24 hrs and steep slopes have a 15 foot

Explanation:

Heavy rainfall in a frequent and widespread natural hazard which may lead to flooding and landslides in hilly areas as the steep slopes have a certain degree of angle and nature of terrain also impacts the flow of geomaterials from above like slopes from 0 to 5 degrees are of gentle and those of 60 to 100 are too steep that of 30 to 60 are steep so it depends upon the amount of rainfall over the region.

within these regions are all the major types of biomes in the world. a biome is a community of animals and plants spreading over an extensive area with a relatively uniform climate. some diverse biomes represented in north america include desert, grassland, tundra, and coral reefs.
