Pollution in the air results in the melting of glaciers. What 2 spheres are involved?
Atmosphere and Cryosphere
What is Replication and why is it important in an experiment?
Replication occurs after repetition. Replication is the process of a DIFFERENT SCIENTIST following the SAME PROCEDURES to perform an experiment. If an experiment cannot be replicated, you have to redesign it.
