Answer 2

Human activities can increase landslides risks. They include clear-cutting, mining and quarrying, bad agricultural practices, and construction activities.  

Explanation:

• Landslides may be triggered by natural processes such as heavy rainfall and earthquakes. They can also be triggered and aggravated by human activities.
• Clear cutting is a method done by logging companies to cut down every marketable tree from a selected area to harvest timber.
• Deforestation or removal of trees that hold water and topsoil may cause landslides.
• Slash-and-burn is a method that cuts down and burns off the existing vegetation. It is a form of deforestation because the land is converted to other uses.
• Mining and quarrying operations use explosives in their blasting techniques to break rocks and gather ore deposits. They cause land areas to slide due to the vibrations from the blast.
• Construction activities such as building of roads and railways may interfere or change the natural drainage of water.
