Question

which human activities cause sudden changes to earth’s surface? choose all answers that are correct. building tunnels through mountains erecting wind turbines planting crops in fields cutting vast areas of forest

Explanation:

• Building tunnels through mountains involves excavating large amounts of rock and earth, which abruptly alters the mountain's structure and the Earth's surface.
• Erecting wind turbines requires clearing land, installing concrete foundations, and constructing towers, which causes sudden localized changes to the surface.
• Planting crops in fields is a gradual, low-impact activity that modifies the surface slowly over time rather than causing sudden change.
• Cutting vast areas of forest (deforestation) removes large swathes of vegetation quickly and disrupts the topsoil, leading to sudden changes in the Earth's surface.

Answer:

• building tunnels through mountains
• erecting wind turbines
• cutting vast areas of forest
