Unit 1: Earth Science – Lesson 1a Nature of Science EEn (Chapter 1) Grand Staircase, Escalante Wilderness, Utah El Caracol, an observatory built by the ancient Maya of Central America, oldest known observatories in the Americas. What is Earth Science? Earth Science is the scientific study of Earth and the universe around it. Scientist believe that natural events, or phenomena, can be explained through careful observation and experimentation.

Unit 1: Earth Science – Lesson 1a Nature of Science EEn (Chapter 1) Branches of Earth Science

Unit 1: Earth Science – Lesson 1a Nature of Science EEn (Chapter 1) Astronomy The scientific study of the universe beyond Earth. Astronomy is one of the oldest branches of Earth science. In fact, the ancient Babylonians charted the positions of planets and stars nearly 4,000 years ago.

Unit 1: Earth Science – Lesson 1a Nature of Science EEn (Chapter 1) Meteorology The scientific study of the Earth’s atmosphere, especially in relation to weather and climate. Meteorologists use satellites, radar, and other technologies to study atmospheric conditions that produce weather. Others continue to use observations from the wind speed, wind direction, temperature, dew point, humidity, barometric pressure, and rainfall to predict or forecast the weather.

Unit 1: Earth Science – Lesson 1a Nature of Science EEn (Chapter 1) Oceanography The scientific study of the oceans Including the properties and movements of ocean water, the characteristics of the ocean floor, And the organisms that live in the ocean. Oceanographers work from land or on research ships with special instruments for studying the waves, tides, ocean currents, and the ocean floor to obtain clues to the Earth’s history or to locate mineral deposits.

Unit 1: Earth Science – Lesson 1a Nature of Science EEn (Chapter 1) Geology The scientific study of the origin, history, and structure of the Earth and the processes that shape Earth. Geologists explore Earth’s crust for deposits of coal, oil, gas, and other natural resources. They study the forces within Earth to predict earthquakes and volcanic eruptions, in addition to studying fossils in order to learn about the Earth’s past. Reference: Holt (2010) Ch1.1, pg 5-8

Unit 1: Earth Science – Lesson 1a Nature of Science EEn (Chapter 1) Environmental Science The relatively new field of science, in order to study the ways in which humans interact with the environment. Many fields of study, such as Earth science, biology, and the social sciences, contribute to environmental science. The goal of environmental science is to understand and solve problems that result from how we use natural resources and how our actions affect the environment.

Unit 1: Earth Science – Lesson 1a Nature of Science EEn (Chapter 1) Subspecialties of Earth Science 1.Climatology – Study of Weather Patterns 2.Paleontology – Study of Fossils 3.Hydrology – Study of Earth’s Waters 4.Ecology – Study of Habitats of Organisms 5.Geochemistry – Study of Earth’s Composition 6. Tectonics – Study of Earthquakes, Volcanoes and internal plate movements

Unit 1: Earth Science – Lesson 1a Nature of Science EEn (Chapter 1) Why is Earth Science Important? By understanding how natural forces shape our environment, Earth scientists can better predict:

Unit 1: Earth Science – Lesson 1a Nature of Science EEn (Chapter 1) Earth’s Systems

Unit 1: Earth Science – Lesson 1a Nature of Science EEn (Chapter 1) Atmosphere Is the gaseous layer that surrounds the Earth Nitrogen is the most abundant gas in the atmosphere + = 1% = 99%

Unit 1: Earth Science – Lesson 1a Nature of Science EEn (Chapter 1) Hydrosphere Part of the Earth that is composed of water: oceans, seas, lakes, rivers, glacier, and atmosphere Artesian wells are examples of groundwater Water makes up 70% of Earth’s surface; 97% of this water is contained in the salty oceans. Remaining 3% is fresh water found in lakes, rivers, streams, glaciers, polar ice sheets, and underground in soil and rock.

Unit 1: Earth Science – Lesson 1a Nature of Science EEn (Chapter 1) Lithosphere or Geosphere This sphere includes all of the rock and soil on the surface of the continents and on the ocean floor. And includes the solid and molten interior of Earth.

Unit 1: Earth Science – Lesson 1a Nature of Science EEn (Chapter 1) The asthenosphere is a partially molten layer that behaves like a soft plastic. The asthenosphere is located underneath the lithosphere and is about kilometers underneath the earth's surface. Lithosphere & Asthenosphere

Unit 1: Earth Science – Lesson 1a Nature of Science EEn (Chapter 1) Biosphere The Biosphere is composed of all of the forms of life in the lithosphere, in the hydrosphere, and in the atmosphere. The biosphere is also contains any organic matter that has not decomposed. (extends from deepest parts of the ocean to few kilometers above Earth’s surface)

Unit 1: Earth Science – Lesson 1a Nature of Science EEn (Chapter 1) Earth’s systems (spheres) are interdependent. Meaning they are interact with each other. If something impacts one system it will have some type of impact on the others.
