Practice Listening: Select Missing Word ID: #41057 Short Continental Drift
Instructions ›
You will see a video explaining the theory of Continental Drift and how the continents have changed over time. At the end of the recording the last word or group of words has been replaced by a beep. Select the correct option to complete the recording.

Transcript:

Continental Drift is the theory that the continents have shifted, changing in both shape and location throughout the history of the Earth. Geologists believe that more than 500 million years ago, there were six major continents spread out along the equator. Over the next 100 million years, the continents drifted together, forming 2 huge landmasses. They continued to move until about 225,000,000 years ago when they met and formed a single massive continent, Pangaea. This supercontinent fragmented into new continents, which continued to move and reshape throughout the Triassic, Cretaceous and Quaternary periods, ultimately forming the continents we know today (as outlined in modern maps).

Option 2: "as outlined in modern maps"

Explanation: This option is correct as it directly reflects the concluding statement of the text, which states that the continents have reshaped into the forms we recognize today, as shown in modern maps. This aligns perfectly with the overall theme of continental drift and the historical context provided.

Option 1: "through the process of evolution"

Explanation: This option is incorrect because the text does not mention evolution as a factor in the formation of continents. Instead, it focuses on the movement and shifting of continents over time, which is unrelated to biological evolution.

Option 3: "known as the current layout"

Explanation: This option is incorrect because while it suggests a current arrangement, it lacks the specificity and context provided in the text. The phrase 'current layout' does not capture the historical process of continental drift and the reference to modern maps.

Option 4: "due to volcanic activity"

Explanation: This option is incorrect as it introduces a specific cause (volcanic activity) that is not mentioned in the text. The text discusses the movement of continents rather than attributing their formation to volcanic processes.
