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. * 7 points
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
weather
photosynthesis

Explanation:

1. Rain - caused erosion: Rain (hydrosphere) erodes land (geosphere), can affect air moisture (atmosphere) and organisms living in the area (biosphere).
2. Weathering of rocks to create soil: Rocks (geosphere) are weathered by air (atmosphere), water (hydrosphere) and sometimes organisms (biosphere).
3. Wind erosion: Wind (atmosphere) erodes land (geosphere), can carry particles that affect water bodies (hydrosphere) and living things (biosphere).
4. Plant roots breaking down rocks into soil: Plants (biosphere) interact with rocks (geosphere), and can also affect water and air in the area.
5. Creation of a Fjord: Glacial ice (hydrosphere in frozen form) carves land (geosphere), and the resulting water - filled valley affects the atmosphere and biosphere.
6. Weather: Involves interactions between the atmosphere, hydrosphere (water in different states), geosphere (land affects weather) and biosphere (organisms can affect weather on a small scale).
7. Photosynthesis: Plants (biosphere) use carbon - dioxide from the atmosphere, water from the hydrosphere and nutrients from the geosphere.
