For the first question about Alfred Wegener's hypothesis on continental drift, the correct answer is:
- The discovery of seafloor spreading
To prove Wegener's hypothesis on continental drift, the discovery of seafloor spreading was a crucial piece of evidence. Seafloor spreading refers to the process where new oceanic crust is formed at mid-ocean ridges and spreads apart, pushing the existing crust away on both sides. This discovery provided observational evidence for the movement of Earth's tectonic plates and supported Wegener's idea that continents were once joined as a single landmass and have since moved apart.
For the second question about human activity changing land use and leading to the growth of large cities, the correct answer is:
- Industrialization
Since the 1800s, industrialization has been the main human activity that has changed land use and contributed to the growth of large cities in many countries. Industrialization involves the development of industries and factories, which led to the concentration of population and urbanization as people migrated from rural areas to work in cities. The expansion of industries and the associated infrastructure like transportation systems, housing, and services have transformed the land and facilitated the growth of urban areas.
For the third question about a description of a specific relationship under given conditions in the natural world, the correct answer is:
- A scientific law
In the context of scientific knowledge and understanding, a scientific law represents a description of a specific relationship under given conditions in the natural world. A scientific law is a well-established and highly reliable statement that succinctly describes and predicts a consistent phenomenon or behavior in nature. Unlike theories or hypotheses, which explain why or how something happens, scientific laws simply describe what happens in a repeatable and predictable manner.
