Question

visit https://dinosaurpictures.org/ancient - earth#220 play around with the interactive globe for a minute or two and make some general observations. you can even try viewing the city you live in at different points in time. 1. make some general observations about the globe at different points in time. give at least three specific pieces of information. 2. how are the continents different during this time? 3. do you think all dinosaurs had equal access to all continents during their lifetime? explain your thinking. 4. name a few specific implications of this timeline of the continents’ separation.

Explanation:

1. General observations about the globe could include noting the position of continents, the presence of land - bridges at different times, and the distribution of water bodies. For example, during the time of the first dinosaurs, the continents were likely closer together in a super - continent like Pangaea.
2. During the time of the first dinosaurs and before the extinction, continents were in different configurations. Pangaea was breaking apart, which led to different climates and habitats on each emerging continent.
3. Not all dinosaurs had equal access to all continents. As the continents drifted apart, physical barriers like oceans and mountain ranges formed, restricting the movement of dinosaurs.
4. Implications of the continents' separation include the evolution of unique species on different continents due to isolation, changes in global climate patterns as ocean currents and wind patterns were affected, and the development of different ecosystems.

Answer:

1. Three specific pieces of information could be: (1) During the time of the first dinosaurs, the continents were joined in a super - continent. (2) As time passed, the continents started to drift apart. (3) By the time of dinosaur extinction, the continents had moved significantly.
2. The continents were in different positions and configurations. Pangaea was splitting, creating new coastlines and separating land masses.
3. No. As the continents drifted, physical barriers formed, limiting the movement of dinosaurs between continents.
4. Unique species evolution on different continents, changes in climate patterns, and development of distinct ecosystems.
