Based on the passage, how did the existence of Navajo sandstone lead to the hanging gardens? The existence of Navajo sandstone allowed water to flow through its pores, until it reached a different type of stone, moved horizontally, and came out the side of the cliff. This water was necessary for the plants to survive, leading to the hanging gardens.
The existence of Navajo sandstone led to a dry, hot climate, in which plants could not grow, except those used in hanging gardens. This dry, hot climate made it difficult for many species of plants to grow, resulting in locals planting the hanging gardens.
The existence of Navajo sandstone led to the creation of many holes with soil, which hanging gardens use to grow up toward the sun. These holes with soil were used by locals to plant lush hanging gardens that visitors could help maintain when they visited.
The existence of Navajo sandstone showed that Native Americans used to dwell in the area by building their houses in the cliffs. In order to decorate their homes, the Native Americans planted many different types of plants in the walls near the water.
