Goals for the Lesson
Give an overview of Earth Science, a broad field with numerous subfields.
Name the Earth Science discipline that studies the solid portion of the planet as geology.
Explain that oceanography is a subfield of Earth science that focuses on different features of the ocean. It is divided into several branches.
Define meteorology as the study of the atmosphere within the discipline of Earth science.
Recognize that astronomy is Earth science expanded to study other regions of the solar system and universe.
Describe a few other Earth Science subfields and how they connect to the study of
Earth sciences are the fields of study concerned with the solid Earth, its waters, and the air that envelops it. They include the geologic, hydrologic, and atmospheric sciences with the broad aim of understanding Earth's present features and past evolution and using this knowledge to benefit humankind.
Understanding Earth's current characteristics and previous evolution is the main goal of Earth sciences, and when applicable, they apply this knowledge to advance humans. Therefore, the primary tasks of an Earth scientist are to observe, characterize, and categorize every aspect of the planet, whether or not it is characteristic; to develop theories to account for the features' existence and evolution; and to come up with methods for evaluating the relative merits of competing theories. The most tenable, palatable, and durable concepts are thus formed in this manner.
The immediate surface of the solid Earth, the ground beneath it, the ocean and air above it, and the ground above are all parts of the physical environment that humans live in. Early people engaged in greater
