In 1803, the Louisiana Purchase doubled the size of the United States by adding 828,000 square miles of land to the nation. This acquisition resulted in the U.S. having unexplored territory. So, in 1803, President Thomas Jefferson asked Congress for approval to fund an expedition. The goals of the expedition were to explore the new territory and to find a practical route to the western part of the country. Jefferson chose Meriwether Lewis to lead this expedition. Lewis selected William Clark as second in command. This was the birth of the Lewis and Clark Expedition.

Although plants don't talk, they do communicate with each other by sending messages. For example, scientists have found that some trees can communicate to share resources like water. They do this by sending messages through an underground network. A certain kind of fungus connects all the trees in the forest together, forming a large network. Scientists believe this information-sharing web may allow larger, older trees to help younger trees survive. This improves the health of the entire forest. The details of how the communication works are still obscure, so further research is needed to better understand the process.

Read the passage and then answer the question.
Sedimentary rock forms in layers over time. When the layers form, plant and animal remains can create fossils in the rock. Older rock layers are usually found deeper underground. Unfortunately, movements of Earth's tectonic plates can cause some older layers to appear higher than younger layers. This movement makes determining the age of rocks challenging. However, geologists can use fossils to help them decipher the age of rock layers. This is why fossils are so important.
