1) Land cover and land use are related, and humans can change A. neither. B. both. C. land cover only. D. land use only.

The correct answer is B. both.Land cover and land use are related concepts, and humans have the ability to change both. Land cover refers to the physical material at the surface of the earth, such as vegetation, water, or urban infrastructure. Land use, on the other hand, refers to the human purpose or function of a particular piece of land, such as residential, commercial, or agricultural use.Humans can change both land cover and land use through various activities, such as urbanization, deforestation, or agricultural expansion. For example, when a forest is cleared for the construction of a city, the land cover changes from forest to urban infrastructure, and the land use changes from a natural ecosystem to a residential or commercial area.Therefore, the correct answer is B. both, as humans can change both land cover and land use.
