This Grade 4 Earth Science reading passage aligns with NGSS standard 4-ESS3-1 and introduces students to the locations and extraction methods of fossil fuels. The passage explains how coal is found in layers underground and extracted through mining, while oil and natural gas are trapped in porous rock formations deep below the surface and removed through drilling. Students discover why different regions of the world have different fossil fuel deposits based on their geological history. The passage also introduces the technology required for extraction and briefly mentions environmental impacts. Audio-integrated features support diverse learners by providing text-to-speech options. This foundational lesson prepares students for hands-on investigations about natural resources and energy. The reading uses age-appropriate vocabulary and real-world examples to build understanding of how humans obtain energy resources from Earth. Comprehension activities, writing prompts, and graphic organizers reinforce key concepts about fossil fuel locations and extraction methods.

Coal is mined, while oil and natural gas are drilled.
Fossil fuels are energy sources formed from the remains of plants and animals that lived millions of years ago. These fuels include coal, oil, and natural gas. We find them underground in specific places called geological formations, which are layers and structures of rock that formed over time. Understanding where fossil fuels are located helps us obtain the energy we need for electricity, transportation, and heating.
Coal is found in layers deep in the earth. These layers formed when ancient plants died and were buried under mud and water. Over millions of years, heat and pressure turned these plant remains into coal. People extract coal through mining, which means digging it out of the ground. Some mines go deep underground, while others remove layers of soil from the surface to reach the coal below.
Oil and natural gas form differently than coal. They come from tiny sea creatures that died and settled on ocean floors long ago. These remains got trapped in porous rock, which is rock with tiny holes like a sponge. The oil and gas fill these holes deep underground. To get them out, workers use drilling, which means making deep holes in the ground with special equipment. The oil and gas then flow up through pipes.
Different parts of the world have different amounts of fossil fuels. This depends on what happened in that area millions of years ago. Places that once had large forests may have coal. Areas that were once covered by ancient oceans may have oil and gas. Finding and removing fossil fuels requires advanced technology and can affect the environment around the extraction sites.
