Answer 1

1. Volcanic eruption. A volcano (in the geosphere) can eject volcanic gases and debris into the atmosphere (air).

2. Cryosphere and hydrosphere. The ice (in the cryosphere) melts into the ocean (in the hydrosphere).

3. Making hypotheses. Making a hypothesis (a guess about how the world works) is often the first step in a scientific investigation.

Answer 2

You really should do your own homework-- all three of these answers are in your book...
