Sunlight is absorbed when it hits Earth. Trees absorb sunlight to make their food. Concrete absorbs sunlight during the day, then releases it as heat during the night. How are humans changing the environment by cutting down trees to build cities?

Question

a
They are making the seasons in the environment shorter by replacing trees with concrete.
b
They are decreasing the temperature by replacing trees with concrete.
c
They are increasing the temperature by replacing trees with concrete.
d
They are making the seasons in the environment longer by replacing trees with concrete.

Answer 1

c. They are increasing the temperature by replacing trees with concrete.

Trees help regulate the temperature by providing shade and cooling the air through the process of transpiration. When trees are cut down to build cities, they are replaced with concrete which absorbs and retains heat, leading to an increase in temperature in urban areas, known as the urban heat island effect. This can lead to higher energy consumption for cooling and increased air pollution levels.
