Explanation:
Two molecules with the chemical formulas C₆H₁₂O₆ and C₆H₁₂O₂ are probably monosaccharides.
Monosaccharides is the basic unit of carbohydrates. All monosaccharides have the formula (CH₂O)
.
Monosaccharides most important are glucose, fructose, etc.
C
A Land mass is large geographical area that is surrounded by oceans. Therefore this can be synonymous to continents.
Explanation:
The crust is divided into tectonic plates that are dynamic because they move on top of the semi-plastic mantle. The movement of the tectonic plates is driven by the convection currents of the mantle that drag along the crust above. The tectonic plates collide at convergent boundaries where tectonic plates are consumed as one is subsided into the mantle. On the other hand, new crust is formed at divergent boundaries where two tectonic plates move away from each other and magma rises from the mantle and cools into new crust.
The convection currents occurs because the lower mantle is hotter and less dense compared to the cooler denser upper mantle. Therefore the upper mantle always tends to sink as the lower mantle rises. These convection currents are the same as in any other fluids that are disproportionately heated.

Answer:
Humans impact the physical environment in many ways: overpopulation, pollution, burning fossil fuels, and deforestation. Changes like these have triggered climate change, soil erosion, poor air quality, and undrinkable water.
