Read the following sentences from the text.
"Dead plants and animals usually break down and rot away, but sometimes their remains become fossils. Think about the Archaeopteryx that died millions of years ago. Its body may have settled to the bottom of a river or lake. Then layers of sand covered the body. The layers created a shell around the skeleton that kept it from breaking down or being eaten by other animals.
Over millions of years, minerals in the water saturated the bones. Minerals are the solid materials that make up rocks. Eventually, minerals replaced all the chemicals in the bones. The bones had transformed into rocks, but they still looked like the bird’s skeleton."
What conclusion can you draw from this evidence? Audio
A fossil is usually created in a lab by scientists.Audio
It is easier to find fossils of ocean animals than land animals.Audio
Animals who die on a rock turn into fossils.Audio

Read the following sentences from the text.
“Igneous rocks form when the melted rock inside Earth cools and hardens. These rocks have a uniform texture. They are made up of grains that are packed closely together. Igneous rocks can be smooth and shiny or filled with a lot of air bubbles.”

1. moving and changing
2. It takes a lot to form a fossil and finding one is a big deal.
3. Rocks are constantly forming on Earth.
4. People can learn about the history of earth through rocks and fossils.
5. the way something feels
6. and
7. Igneous, sedimentary, and metamorphic
8. The discovery of Archaeopteryx is important because it gives scientists direct physical evidence about ancient life and how organisms changed over time. The passage explains how the bird’s skeleton was preserved by layers of sand and minerals that turned the bones to rock, so the fossil still looked like the original skeleton. Because fossils form only under special conditions and over millions of years, finding one like Archaeopteryx helps scientists learn about evolution (for example, links between dinosaurs and modern birds) and Earth’s history.
