Introduction to Earth Science Mr. Ross Brown
Aim: What are the many areas of Earth Science? • Do now: What are the different Sciences we will study in class this summer? • Earth Science: the study of the Earth and the universe around it.
Geology • The study of the origin, history, and structure of the solid Earth and the processes that shape it.
Geology, cont. • Some jobs for geologists: • Petrologist and Mineralogist: look for minerals and oil deposits • Seismologist: study and forecast earthquakes and volcanoes • Paleontologist: study the fossil record to understand the history of the Earth
Oceanography • The study of the world’s oceans • Oceans cover 71% of the Earth's surface & contain 97% of the planet's water, yet over 95% of the underwater world is unexplored.* * www.noaa.gov/ocean.html
Oceanography, cont. • Oceanographers study many things: • On research ships, some study water quality • Some study waves, tides, or currents • Some study the ocean floor to understand the Earth’s history or to find resources • Some study marine plants and animals
Meteorology • The study of the Earth’s atmosphere • Atmosphere: thick blanket of gases surrounding the Earth
Meteorology, cont. • Careers for Meteorologists: • Using technology (satellites, radar) to study variations in atmospheric conditions that produce weather. • Some measure & collect weather data • Some use these data to prepare weather maps • Some use these maps to forecast weather
Astronomy • The study of the universe beyond Earth • Astronomy dates back thousands of years • Astronomers use land- and space-based telescopes, satellites, space probes • They study the Moon, planets, stars, galaxies, and the whole universe
Review • What are the 4 main branches of Earth Science? • What is Ecology? What is an Ecosystem?
Earth’s areas of study • Geosphere: the solid Earth • Hydrosphere: the water on the planet • Atmosphere: the gases surrounding the Earth • Other scientists study Biology, the living world • Biology and Earth Science Ecology • Relationships between living things and their environments
Ecosystem • A community of organisms and the environment they inhabit • The largest is Biosphere: all life on Earth and the physical environment that supports it. Tropical Rain Forest Tidal Pool
Ecosystems Tundra Savannah
