Hi guys its long since i posted but i was busy doing my research on my action post.
Iam Danson from Tigithi Boys High School.
What is a landslide and what causes one?
A landslide is defined as the movement of a mass of rock, debris, or earth down a slope. Landslides are a type of “mass wasting,” which denotes any down-slope movement of soil and rock under the direct influence of gravity. The term “landslide” encompasses five modes of slope movement: falls, topples, slides, spreads, and flows. These are further subdivided by the type of geologic material (bedrock, debris, or earth). Debris flows (commonly referred to as mud flows or mudslides) and rock falls are examples of common landslide types.
Almost every landslide has multiple causes. Slope movement occurs when forces acting down-slope (mainly due to gravity) exceed the strength of the earth materials that compose the slope. Causes include factors that increase the effects of down-slope forces and factors that contribute to low or reduced strength. Landslides can be initiated in slopes already on the verge of movement by rainfall, snow melt, changes in water level, stream erosion, changes in ground water, earthquakes, volcanic activity, disturbance by human activities, or any combination of these factors. Earthquake shaking and other factors can also induce landslides underwater. These landslides are called submarine landslides. Submarine landslides sometimes cause tsunamis that damage coastal areas.
Hey Danson! Wow, awesome research round! I really like how you put so much information into a few nice and easy to follow paragraphs. I can tell you really put a lot of effort into your research round. When I was reading your information, I immediately thought of a landslide that happened in Kenya that I had heard on the news last year. It was very tragic, many people died because of it, which is so sad. Perhaps if your interested, you could look into how many people are affected by landslides every year and just more so the statistics behind landslides. I’ll link the article to the landslide that happened in Kenya, as well as a website to help your research-
