Question

how does increased vegetation typically impact urban temperatures?
it lowers temperatures by absorbing heat.
it has no effect on temperatures.
it decreases biodiversity.
it raises them significantly.

Explanation:

Plants absorb heat through processes like transpiration. Increased vegetation means more heat absorption, which lowers urban temperatures. The option "It lowers temperatures by absorbing heat" is correct. The option "It has no effect on temperatures" is wrong as vegetation clearly impacts heat. "It decreases biodiversity" is about biodiversity, not temperature. "It raises them significantly" is the opposite of what vegetation does.

Answer:

It lowers temperatures by absorbing heat.
