Question

1. practice: analyzing changes in earths surface question 1 identify three factors that contribute to slope stability. question 2 explain some ways in which mass movement can affect wildlife. question 3 why are saturated sediments so weak?

Explanation:

Question 1: Cohesion between soil particles resists movement. Friction between layers helps hold the slope in place. Vegetation roots bind soil, increasing stability.
Question 2: Mass movement can destroy wildlife habitats, such as burying forests or meadows. It can also disrupt migration routes and cause direct harm or death to animals caught in the movement.
Question 3: Saturated sediments are weak because water fills the pore - spaces, reducing particle - to - particle contact and friction. The water also adds weight, increasing the driving forces for slope failure.

Answer:

Question 1: Cohesion, friction, vegetation.
Question 2: Destroys habitats, disrupts migration routes, causes harm or death to animals.
Question 3: Water fills pore - spaces reducing particle contact and friction and adds weight.
