Question
How does the fern Glossopteris provide evidence for the movement of the continents?(1 point)
Responses
It existed in the Permian period.
It existed in the Permian period.
It is the oldest plant on Earth.
It is the oldest plant on Earth.
It lived at the same time as Lystrosaurus.
It lived at the same time as Lystrosaurus .
It was found on many continents.
Correct response: It was found on many continents.
Explanation: By finding fossils of the fern Glossopteris on multiple continents, scientists have been able to infer that the continents were once connected and have since drifted apart. This provides evidence for the concept of continental drift, which is a key component of the theory of plate tectonics.
The fern Glossopteris provides evidence for the movement of the continents because it was found on many continents.
To determine the answer to this question, we need to examine the provided responses and analyze the information given. The question is asking about how the fern Glossopteris provides evidence for the movement of the continents.
Let's consider each response and assess if it is a valid explanation:
1. "It existed in the Permian period."
This response does not directly address the movement of continents, but rather mentions the time period in which the fern existed. While the Permian period is relevant to Earth's history, it does not provide direct evidence for continental movement.
2. "It is the oldest plant on Earth."
This response also does not mention the movement of continents. While it provides information about the fern's age, it does not specifically connect it to continental movement.
3. "It lived at the same time as Lystrosaurus."
This response suggests that Glossopteris and Lystrosaurus coexisted. While this information is relevant to understanding the time period, it does not directly support the idea of continental movement.
4. "It was found on many continents."
This response provides the most relevant evidence for the movement of continents. If the fern Glossopteris is found on multiple continents, it suggests that these continents were once connected and have since moved apart. Therefore, this response is the correct answer.
Based on the analysis, the correct response is: "It was found on many continents."
