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.

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).

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.

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.
