List two ways in which the biosphere would be impacted in the absence of the geosphere. use complete sentences.

Well, the biosphere could me impacted in multiple different ways but I'll only give you two since that is what you're asking for. One example would be plants. If there was no geosphere, most plants would not have anything to grow on like grass, in the cracks of rocks etc. Most land living animals would not be able to survive in water so they would not survive without the geosphere.
