Which one of the following was NOT used as support of Wegener's continental drift hypothesis? (A) fossil evidence (B) paleomagnetism (C) the fit of South America and Africa (D) ancient climates

a. Why did most scientists reject Wegener's hypothesis of continental drift?

b. Do you think the scientists of Wegener's time should have accepted his hypothesis? Why or why not?

How does an increase in confining pressure affect a rock's melting temperature? (A) The melting temperature increases. (B) The melting temperature decreases. (C) The melting temperature is stabilized. (D) It has no effect on the melting temperature.

What evidence was used to support continental drift?

a. What evidence supported the hypothesis of continental drift? b. How did fossils provide evidence for continental drift? c. Deposits of coal have been found beneath the ice of Antarctica. But coal only forms in warm swamps. Use Wegener's hypothesis to explain how coal could be found so near to the South Pole.

b. positively charged and negatively charged parts of polar covalent molecules attract.

c. ions with opposite electrical charges attract.

d. two atoms exchange protons.

e. an element has two types of isotopes.

Which of the following was NOT used by Wegener to support his hypothesis of continental drift?

a. fossils of land-dwelling animals

b. paleomagnetic data

c. coal beds in Antarctica

d. glacial deposits

According to continental drift theory, when did the supercontinent of Pangaea begin to break up?

Why does subduction occur?

Hot spots move with continental plates. True or false?

Imagine that you are studying seafloor spreading along two different oceanic ridges. Using data from a magnetometer, you produced the two accompanying maps. From these maps, what can you determine about the relative rates of seafloor spreading along these two ridges? Explain .

Place these terms in the correct order so they begin at Earth's surface and move toward the center: inner core, asthenosphere, lower mantle, lithosphere, outer core.

Describe two ways that minerals can form.

Which of the following rock types would most likely contain fossils? A. sedimentary rock composed of limestone. B. igneous rock ejected from a volcano. C. metamorphic rock. D. hardened lava.
