deep roots
conical shape

Pine trees have deep roots which enable them to adapt to the climate of the northwestern coniferous forests. Their roots extend deep down to the soil where oxygen content is limited and water is scarce. During the change of seasons when the soil is wet the roots tend to recede and when it is dry the roots tend to spread downward.
