Explanation:

1. The atmosphere is the layer of gases surrounding the Earth that regulates climate and weather.
2. The biosphere includes all living organisms.
3. Water vapor from the hydrosphere evaporates into the atmosphere, forming clouds, which is an interaction between hydrosphere and atmosphere.
4. The cryosphere stores large amounts of freshwater and reflects sunlight, affecting climate.
5. Volcanic eruptions release gases and particles that can affect climate and air quality.
6. A watershed is an area of land where water from rivers and lakes converges into a single river.
7. Weathering is the process responsible for breaking down rocks into smaller pieces.
8. Water freezing in cracks and expanding to break the rock apart is mechanical weathering.
9. Plants taking in carbon - dioxide and releasing oxygen through photosynthesis is a crucial interaction between biosphere and atmosphere.
10. The geosphere supplies nutrients and minerals through soil formation to support life in the biosphere.
11. The hydrosphere stores heat energy from the sun and distributes it through ocean currents, contributing to Earth's climate regulation.
12. Rivers carving through the geosphere, creating deep valleys best explains the formation of canyons.
13. The lithosphere is the solid outer layer that contains tectonic plates.
14. Plate tectonics contribute to the formation of mountains by the collision and uplift of Earth's crust.
