How did Alfred Wegener use the observation of glacial striations to support his hypothesis of continental drift?

• He suggested that glaciers formed near the equator in the past.

• He proposed that continents were once connected near the poles.

• He argued that glaciers moved continents to their current positions.

• He claimed that striations were caused by tectonic activity.

What reasoning did Wegener use to connect coal deposits found in different continents to his theory of continental drift?

• Coal deposits indicate that these continents were once covered by oceans.

• Coal forms in swampy areas, suggesting these continents were once connected.

• Coal deposits are found only in tropical regions, proving continental drift.

• Coal deposits are unrelated to continental drift.

Explain how the discovery of mid-ocean ridges contributed to the development of the theory of plate tectonics.

• Mid-ocean ridges showed that continents are stationary.

• Mid-ocean ridges provided evidence of seafloor spreading.

• Mid-ocean ridges proved that the Earth is expanding.

• Mid-ocean ridges indicated that oceans are shrinking.

How does the principle of superposition help geologists understand Earth's geologic past?

• It shows that older rocks are always found at the top of rock layers.

• It helps determine the relative age of rock layers by their position.

• It indicates that all rock layers are the same age.

• It proves that rock layers are formed by volcanic activity.

What evidence did Mary Tharp's mapping of the seafloor provide for the theory of plate tectonics?

• It showed that the seafloor is flat and featureless.

• It revealed rift valleys, supporting the idea of seafloor spreading.

• It indicated that the seafloor is older than the continents.

• It proved that the seafloor is made of a single tectonic plate.

Describe how the study of fossils supports the idea that continents have changed positions over time.

• Fossils show that all life forms have always existed in their current locations.

• Similar fossils found on different continents suggest they were once connected.

• Fossils indicate that continents have always been separated by oceans.

• Fossils prove that continents have never moved.

What role did the discovery of similar mountain ranges on different continents play in supporting the theory of plate tectonics?

• It showed that mountain ranges are formed by ocean currents.

• It indicated that continents were once connected and have drifted apart.

• It proved that mountain ranges are identical worldwide.

• It demonstrated that mountain ranges are unrelated to continental movement.

How does the presence of glacial striations in equatorial regions support the theory of continental drift?

• It suggests that glaciers can form in any climate.

• It indicates that these regions were once located near the poles.

• It proves that the equator was once covered in ice.

• It shows that striations are unrelated to climate.

What reasoning did Wegener use to explain the presence of similar fossils on continents now separated by oceans?

• He suggested that these fossils were carried by ocean currents.

• He proposed that the continents were once connected, allowing species to spread.

• He argued that these fossils evolved independently on each continent.

• He claimed that these fossils were deposited by meteorites.

How does the study of rock layers contribute to our understanding of continental drift?

• It shows that all rock layers are the same age.

• It helps determine the relative age and formation of continents.

• It indicates that rock layers are unrelated to continental movement.

• It proves that rock layers are formed by ocean currents.
