In the early 1900’s, V.M. Slipher studied faint, cloud-like objects in the night sky. He noted that
most of the objects had red shifts. Later, astronomers determined that these objects were
galaxies similar to the Milky Way. Edwin Hubble and Milton Humason published what is now
known as the Hubble law. This law describes the relationship between red shift and the distance
of the object being measured. Which of the following statements best describes the relationship
between the work of Slipher, Hubble and Humason?

Fresh water from the melting ice caps and glaciers dilutes the surrounding salt water. Cold,
salty water in the north Atlantic Ocean normally sinks to the bottom of the ocean and slowly
creeps along until it reaches an area of upwelling. Scientists believe that this process circulates
nutrients and heat throughout the world’s oceans. Some scientists worry that the melting
glaciers will change these salty circulations and therefore change the cycling of nutrients in the
ocean, ultimately impacting food sources for animals living in the ocean.
Which statement is evidence that causes scientists to believe that the biological environment in
the ocean is changing?
11
A
Melting ice is diluting salty ocean water.
B
Melting glaciers will change the cycling of nutrients in the ocean.
