The picture shows how air in a room is warmed by a heater. How does this system compare to the way heat from the core of the Earth reaches the surface?

C. Both systems use convection currents to transfer heat.

D. Both systems use conduction to transfer heat.

Look at the map below. The dots around the Pacific Ocean show where earthquakes happened.

• Is the land under most of the Pacific Ocean made of one tectonic plate or two? Support your answer.

• What other kind of sudden geologic event is also likely to happen on the land around the Pacific Ocean?

Most of the United States is a part of which tectonic plate?

A. Pacific Plate B. Eurasian Plate C. North American Plate D. South American Plate

Which of the following is the most likely cause of earthquakes?

A. shifting rock layers B. crashing meteorites C. rotation of the core D. magnetic force

Which event most likely caused the formation of folded mountain ranges?

A. Tectonic plates on the earth pushed together. B. Tectonic plates on the earth pulled apart. C. Tectonic plates on the earth slid past each other. D. Tectonic plates on the earth broke into small

pieces.

Earthquakes occur along the San Andreas Fault in California. Which statement best describes plate motion in the area during the time between earthquakes?

A. Plate motion stops, and plate tension decreases. B. Plate motion continues, and plate tension

increases. C. Plate motion stops, and only the mantle moves. D. Plate motion reverses, and plates return to their

original positions.

• In the late 1500s a Dutch mapmaker named Abraham Ortelius studied new maps of the world. He noticed that the Americas seemed to fit with Europe and Africa like pieces in a jigsaw puzzle, as shown below. He suggested that the Americas were violently separated from Europe and Africa by earthquakes and floods.• In 1872 a Frenchman, Elisee Reclus, proposed that the continents drifted in a

random way, but he didn’t know why. He suggested that their collisions formed mountain ranges and caused earthquakes, as well as leaving empty places for oceans• An American, Frank B. Tailor, suggested that gravitational or tidal forces caused by

the moon were responsible for the movement of the continents.• In 1912 Alfred Wegener of Germany proposed the theory of continental drift,

based on geology and fossils. He thought the continents somehow pushed their way through the ocean floor, but couldn’t say what might cause that to happen. His theory led to the present-day theory of plate tectonics.

Which evidence would Alfred Wegener have presented to show that the continents have moved over time?

A. Similar plants grow in Africa and Asia today. B. Similar animals live in North America and South

America. C. Rocks found in Europe have minerals that are

identical to those in different rock types found in Asia.

D. Fossils of tropical plants are found in Antarctica, and glacial deposits are found in hot, dry parts of Africa.

Which scientist in the passage first described how moving continents cause some landforms and geological events?

A. Abraham Ortelius B. Alfred Wegener C. Frank B. Tailor D. Elisee Reclus
