2 Objectives Compare the areas of study within Earth science. Section 1.1Earth ScienceObjectivesCompare the areas of study within Earth science.Identify Earth’s systems.Explain the relationships among Earth’s systems.Explain why technology is important.
3 Section 1.1Earth ScienceEarth science encompasses five areas of study: astronomy, meteorology, geology, oceanography, and environmental science.Review Vocabularytechnology: the application of knowledge gained from scientific research to solve society’s needs and problems
6 The Scope of Earth Science Section 1.1Earth ScienceThe Scope of Earth ScienceEarth science can be broken into five major areas of specialization:Astronomythe study of objects beyond Earth’s atmosphere
10 The Scope of Earth Science Section 1.1Earth ScienceThe Scope of Earth ScienceGeologythe study of materials that make up Earth, the processes that form and change these materials, and the history of the planet and its life-forms
11 The Scope of Earth Science Section 1.1Earth ScienceThe Scope of Earth ScienceOceanographythe study of Earth’s oceansEnvironmental sciencethe study of the interactions of organisms and their surroundings

13 Section 1.1Earth ScienceEarth’s SystemsScientists who study Earth have identified four main Earth systems:
14 Earth’s Systems Geosphere Earth Science Section 1.1Earth ScienceEarth’s SystemsGeospherethe area from the surface of Earth down to its center
15 Earth’s Systems Atmosphere Hydrosphere Section 1.1Earth ScienceEarth’s SystemsAtmospherethe blanket of gases that surrounds our planetHydrosphereall the water on Earth, including the water in the atmosphere
16 Earth’s Systems Biosphere Section 1.1Earth ScienceEarth’s SystemsBiosphereall organisms on Earth as well as the environments in which they live
17 Earth’s Systems Earth Science Section 1.1Earth ScienceEarth’s SystemsAll of Earth’s systems are interdependent. Notice how water from the hydrosphere enters the atmosphere, falls to the biosphere, and soaks into the geosphere.
18 Section 1.1Earth ScienceTechnologyTechnology is not used only to make life easier. It can also make life safer.Technology is important, not only in science, but in everyday life.
19 1Study GuideKey ConceptsSection 1.1 Earth ScienceEarth science encompasses five areas of study: astronomy, meteorology, geology, oceanography, and environmental science.Earth is divided into four systems: the geosphere, hydrosphere, atmosphere, and biosphere.Earth systems are all interdependent.
20 1Study GuideKey ConceptsSection 1.1 Earth ScienceIdentifying the interrelationships between Earth systems leads to specialties and subspecialties.Technology is important, not only in science, but in everyday life.Earth science has contributed to the development of many items used in everyday life.
21 1 The Nature of Science Which phrase best defines technology? 1.1 Section QuestionsWhich phrase best defines technology?a. the creation of scientific knowledgeb. the application of scientific knowledgec. electronic equipment such as computersd. any type of invention, model, or design
22 1The Nature of Science1.1 Section QuestionsEarth’s systems often interact. Which example represents an interaction between the hydrosphere and the atmosphere?a. water eroding a deep canyonb. water evaporating from the seac. water entering a plant’s rootsd. water seeping into soil and rock
23 1The Nature of Science1.1 Section QuestionsWhy do many Earth scientists specialize into subdisciplines?Answer: Earth science is very broad. It is impossible for any one person to keep up with all Earth science research that is being done. Specializing allows scientists to develop advanced knowledge and skills in their particular subdiscipline.
