Humans affect the physical environment in numerous ways: overpopulation, contamination, burning fossil powers, and deforestation. Changes like these have triggered climate alter, soil erosion, poor air quality, and undrinkable water. These negative impacts can influence human behavior and can provoke mass migrations or battles over clean water.
Answer:
The movement of two continents or plates towards each other refers to the convergent boundaries. The process of plate movement was explained by Alfred Wegener in 1912 in the plate tectonic theory.
The movement of the plates on the surface of the earth is a product of the convective currents that come from within the interior of the planet. There exist three types of plate boundaries based on the arrangement of plate and earth structure such as divergent, convergent, and transform boundary.
The convergence can take place between the two continental landmass, oceanic masses and ocean, and continental landmasses. Where the heavier plate collides and sinks into the mantle.
Hence the geologist using the GPS learns that the movement of two landmasses close to each other is due to the consumption of one plate by another.

Answer:
Geologic time scale is a phase of geologic evolutionary history of earth to present.
Explanation:
- It's a chronological time scale which shows the dating of rocks, and other events that took place on earth during that period. Primarily divided into eons, from the Haden to Archean to Proterozoic to Phanerozoic. All three are called collectively as Precambrian supereon and eon is divided into eras, period and epochs.
- Precambrian starte about 4600 million years ago and ended in 500 million years ago. Based on carbon dating of rocks found 3.8 billion years ago life forms started to emerge, and evidence of plate tectonics motion can be 4280 million ago.
- As compared to the phanerozoic era which started from 500 million years ago to present studied as an era of diverse land and aquatic plants and animals. Subdivided as Paleozoic Era, Cambrian Period, Ordovician Period,Silurian Period, Devonian Period, Carboniferous Period and Permian Period.
- The original time scale has been altered to fit the scientist dating of rocks and geologic evidence that they have collected and is modified from time to time upon newer discoveries.
