1. when the hydrosphere and geosphere interact,

which example best fits?
a. a volcano releasing ash into the air
b. waves eroding a rocky shoreline
c. plants releasing oxygen into the air
d. lava cooling and forming new rock

Explanation:

1. Volcanoes are part of the geosphere. When they release gases into the air (atmosphere), the geosphere interacts with the atmosphere.
2. Convection currents in the mantle cause tectonic plates to move.
3. The San Andreas Fault is a transform boundary.
4. When an oceanic plate sinks below a continental plate, it forms an ocean trench.
5. The point inside Earth where an earthquake starts is the focus.
6. The point on Earth’s surface directly above where an earthquake starts is the epicenter.
7. Vibrations caused by plate movement are seismic waves.
8. Volcanoes can form at both divergent (e.g., mid - ocean ridges) and convergent (e.g., subduction zones) boundaries.
9. The mantle is the thickest layer of Earth.
10. The transfer of heat by movement of fluid material is convection.
11. The inner core is solid metal.
12. Waves (hydrosphere) eroding a rocky shoreline (geosphere) is a hydrosphere - geosphere interaction.

Answer:

1. D. Geosphere

5. C. Focus
6. B. Epicenter
7. B. Seismic waves
8. B. They can form at both divergent and convergent boundaries.
9. B. Mantle
10. B. Convection
11. D. Inner Core
12. B. Waves eroding a rocky shoreline
