The document defines the Earth system as being composed of four interdependent spheres - the hydrosphere, atmosphere, lithosphere, and biosphere. These spheres interact within the defined boundary of Earth. The document also states that destructive forces like natural disasters and constructive forces such as earthquakes and volcanoes can change the Earth by creating new land or destroying areas. However, it argues that life on the planet may not be fully linked since different human behaviors, both positive and negative, impact the environment in varying ways.

2. What is a system
• A system is a collection interdependent parts
enclosed within a defined bundary.
• Within the boundary of the earth is a
collection of 4 interdependent parts called
spheres.

4. what are the main parts of the Earth’s System
• There are 4 main parts that are:
• Hydrosphere (oceans).
• Atmosphere (air).
• Lithosphere (land).
• Biosphere (living things).

6. How do constructive and destructive
forces change the Earth
• Some examples of destructive forces are
natural disasters.
• And some examples of contructive forces are
earthquakes and volcano’s.
• They change the earth because they can do a
new land and they can destruc everything.

8. Do you think life on the planet is
linked
• I think that NO, because some people
throught garbage or, do something wrong,
and other people do good things and help the
planet, so not all the people is okay with the
idea of recycling so I think that no.
