* Gravity's Pull: Gravity constantly pulls everything towards the center of the Earth. On slopes, this pull acts downwards and outwards, creating a force that can overcome the resistance of the soil and rock.
* Wind's Role: While wind can play a role in erosion, it's generally not strong enough to directly cause landslides. Wind can:
* Weaken slopes: Strong winds can dislodge loose materials, making slopes more susceptible to landslides.
* Transport debris: Wind can pick up and carry loose material, potentially contributing to the size and impact of a landslide.
In summary: Gravity is the main force behind landslides, while wind can play a supporting role by contributing to erosion and weakening slopes.
