Earth Science Chapter 1 - Summary Notes

· Because Planet Earth is so vast, we divide it into different areas of study. Geology, oceanography, and meteorology are three of the most common forms of Earth Science.

· Geology studies the solid Earth. A volcanologist is a geologist who studies volcanoes. A seismologist is a geologist who studies earthquakes. A paleontologist is a geologist who studies fossils.

· Oceanography studies the ocean. Physical oceanographers study waves and ocean currents. Biological oceanographers study the plants and animals that live in the ocean.

· Meteorology studies the entire atmosphere. A weather forecaster has a career in meteorology.

· Earth science can also take place outside of our planet. Astronomy is the study of all physical things beyond Earth. It includes stars, asteroids, and planets.

· Models represent objects or systems. They can help us understand things that are too large or too small to see, like an atom or the entire solar system.

· We also use models to explain things that are going on and to help us predict the future.

· The Greenhouse Effect is one important model that scientists use to predict the future of Earth’s atmosphere. Sunlight enters the atmosphere and reaches the Earth, and then the Earth radiates energy back into the atmosphere. Greenhouse gases trap this energy from going into space, so the energy ends up heating the Earth’s surface.

· Scientists usually describe length in meters (m), volume in liters (L) for liquids and cubic meters (m³) for solids, mass in kilograms (kg), and temperature in Celsius (^oC) and kelvins.

· No matter what you’re measuring, always follow instructions and use the right safety equipment when experimenting with Earth science. Don’t take short-cuts, even if it looks safe!
