Explanation:

1. Erosion is the movement of rock pieces by natural agents like wind, water, and gravity.
2. When the cryosphere melts, sea - level rises in the hydrosphere.
3. The Earth's inner core is made of solid iron and nickel, with high heat and pressure.
4. During a landslide, rock and debris move downslope due to gravity and saturation.
5. The asthenosphere is like a liquid while the lithosphere is solid.
6. Animals and other living beings exist on and around ice in the cryosphere shows the interaction between cryosphere and biosphere.
7. Erosion moves rock particles from one place to another, while weathering breaks down rocks into smaller pieces.
8. The Earth's magnetic field deflects deadly solar radiation and cosmic rays.
9. A river basin is a large area of land drained by a river and its tributaries.
10. The geosphere gives nutrients and habitat to living organisms showing the interaction between biosphere and geosphere.
11. The outer core makes a magnetic field by violent convection currents.
12. A sinkhole is a large depression formed by the erosion of limestone or carbonate rock.
13. The cryosphere freezing water from the hydrosphere leads to the formation of glaciers.
14. The hydrosphere affects the lithosphere by causing weathering and erosion of rocks and minerals.
15. Sand dunes are formed by erosion and deposition by wind.
16. Acid rain dissolving rock is an example of chemical weathering.
