Introduction to Earth Science

Study Notes

Earth science is a field with four main branches: Geology, Astronomy, Oceanography, and Meteorology.
Geology is the study of Earth's materials, structures, and processes, including seismology (study of seismic waves and earthquakes), mineralogy (study of minerals), and volcanology (study of volcanoes).
Astronomy deals with the study of celestial bodies and phenomena, encompassing planets, stars, galaxies, and the universe as a whole.
Oceanography focuses on the study of oceans, their physical, biological, and chemical properties, and the impact of climate change.
Meteorology is the study of Earth's atmosphere and atmospheric phenomena, including weather patterns and forecasting.
Earth scientists use various technical terms derived from Greek and Latin roots, such as "geo" meaning Earth and "microbio" meaning tiny organisms.
Earth scientists study a variety of questions related to the Earth, planets, and processes causing environmental changes, aiming to protect and conserve resources for human habitation.
Geologists focus on understanding the Earth's structure and processes, helping predict natural disasters like earthquakes and volcanic eruptions.
Meteorologists study weather patterns and forecast weather conditions to help prepare for potential natural disasters and ensure public safety.
Earth science fields have specific tools and methods for collecting and analyzing data, such as seismographs for measuring seismic waves and satellite data for weather forecasting.
Earth science encompasses various sub-disciplines like limnology, cartography, and geography, broadening our understanding of the planet and its various features.
