Homework
Give two examples of how the Earth system’s four parts can interact with
each other.
Example: Animals (biosphere) can wear paths in Earth’s surface (geosphere).
Identify the parts involved in the following scenarios:
Wind blows a sailboat across a lake.
A bear digs under a log to search for good.
