Which phrase best matches fast changes to the Earth such as volcano, earthquake, landslide?

• A. Slow Changes to the Earth
• B. Landforms
• C. Fast Changes to the Earth
• D. Nonrenewable Energy Sources

Answer: (C)

Fast changes to the Earth describe events that happen quickly, like a volcano erupting, an earthquake shaking the ground, or a landslide moving loose rocks downhill. These are rapid, sudden changes to the surface, so the phrase that fits best is the one that names fast changes to the Earth. The other options don’t fit as well: slow changes refer to processes that happen over a long time, such as weathering and erosion; landforms are the shapes and features of the land, not the speed of change; nonrenewable energy sources relate to resources like coal or oil, not to how quickly the surface changes.
