When forestry services clear out the underbrush in a given area.
True or false: Removing trees leads to an increase in soil and stream temperatures due to decreased shading by tree canopies and the loss of trees evapotranspiration which cool the air around the tree.
True
False
True or false: Trees help cool the planet by absorbing carbon dioxide as part of the photosynthesis process and by evaporating water into the air.
