1. The correct answer is A. The islands of Indonesia have many volcanoes and experience frequent earthquakes because they are located at the boundaries of tectonic plates. Indonesia sits at the intersection of several major tectonic plates, including the Pacific Plate, the Indian-Australian Plate, and the Eurasian Plate. These plates are constantly moving, and where they meet, they can interact in different ways, such as subduction or collision. These interactions can create volcanic activity and lead to earthquakes. This is why Indonesia is part of the Pacific Ring of Fire, which is an area of high volcanic and seismic activity.
To arrive at this answer, we would need to understand the geography and geology of Indonesia. By knowing that tectonic plates play a significant role in shaping Earth's crust, we can infer that the movements and interactions of these plates are responsible for the volcanic and seismic activity in Indonesia. This knowledge can be acquired by studying geology, plate tectonics, and specifically, the geology of Indonesia.
2. The correct answer is B. The scientist can best conclude that the organisms lived around the same time. To arrive at this conclusion, the scientist likely compared the fossil records or other evidence related to these organisms. By analyzing factors such as the age and distribution of the fossils, the scientist can determine the relative timing of when the organisms lived.
To obtain this conclusion, the scientist would likely have used various methods in paleontology, such as studying the fossil record, analyzing geological layers, and dating techniques, among others. By comparing these pieces of evidence, the scientist can make a well-supported conclusion about the organisms' temporal relationship.
