Question

for each of the interactions select the spheres that are affected (include the one that is causing the interaction) most of the below affect 3 - 4 of the listed spheres.
geosphere hydrosphere atmosphere biosphere
rain caused erosion
weathering of rocks to create soil
wind erosion
plant roots breaking down rocks into soil
creation of a fjord

Explanation:

• Rain - Hydrosphere causes erosion on Geosphere, can affect Atmosphere during formation and Biosphere as it impacts life.
• Weathering of rocks - Geosphere process, water (Hydrosphere) can be involved, affects Atmosphere through gas - rock reactions and Biosphere as soil is habitat.
• Wind erosion - Atmosphere (wind) affects Geosphere, can impact Hydrosphere if it moves water - related particles and Biosphere as it changes habitats.
• Plant roots - Biosphere (plants) break down Geosphere rocks, can interact with Hydrosphere through water uptake and Atmosphere through gas exchange.
• Fjord creation - Geosphere (glacial and tectonic processes), Hydrosphere (water filling the fjord), can affect Atmosphere through evaporation and Biosphere as it creates a new habitat.

Answer:

• Rain caused erosion: Geosphere, Hydrosphere, Atmosphere, Biosphere
• Weathering of rocks to create soil: Geosphere, Hydrosphere, Atmosphere, Biosphere
• Wind erosion: Geosphere, Hydrosphere, Atmosphere, Biosphere
• Plant roots breaking down rocks into soil: Geosphere, Hydrosphere, Atmosphere, Biosphere
• Creation of a Fjord: Geosphere, Hydrosphere, Atmosphere, Biosphere
