A. To clarify a common misunderstanding

B. To show in what way Earth is similar to a watch

C. To emphasize the regularity of Earth s movements

D. To connect the concepts of orbits and time

A. They have a significant effect on the axial tilt of Earth.

B. They play a moderating role on Earth’s climate.

C. Their formation could be affected by changes in Earth s orbit.

D. Their melting could result in longer warm seasons.


4.What is the significance of the evidence found on the ocean floor?

A. It negated earlier evidence that Milankovitch found.

B. It led to the development of new methods to measure global climate changes.

C. It helped Milankovitch first formulate his hypothesis.

D. It confirmed Milankovitch’s hypothesis.


5.What did calcite deposits from Devils Hole reveal?

A. Inaccurate information about long-term climate changes

B. Evidence that contradicted Milankovitch s hypothesis

C. Evidence that climate changes occur only locally

D. Variations in Earth’s orbit that had little impact on climate


6.Why does the professor say this:

A. To inform the students about what he will not discuss.

B. To indicate the difficulty of measuring precession.

C. To explain why he plans to spend a long time discussing precession.

D. To clarify that he will provide additional information later.
