What is Earth Science?

Do Now: What does it mean to be dynamic? What does it mean to be dynamic? Is your life dynamic? In what way? Is your life dynamic? In what way?

Earth Science Is NOT a Pure Science Earth Science Is NOT a Pure Science Earth Science IS an Applied Science Earth Science IS an Applied Science

Earth Science is: The study of the earth, its changing systems, and its place in the Universe. The study of the earth, its changing systems, and its place in the Universe.

By understanding how natural forces shape our environment, Earth Scientists may better forecast potential disasters and help save lives and property.

ZONES OR SPHERES Earth is the only planet known (at present) to support life as we know it. Earth is the only planet known (at present) to support life as we know it. It is able to do this because of the interactions among its spheres/zones. It is able to do this because of the interactions among its spheres/zones. ATMOSPHERE: gaseous envelope surrounding Earth, provides living things with oxygen and carbon dioxide. HYDROSPHERE: all water on Earth: includes oceans, streams, rivers, lakes, seas (CRYOSPHERE: snow, ice, glaciers, frozen ground)

Zones or Spheres continued: LITHOSPHERE (aka Geosphere): Earth itself, all physical features except water. OUTER SPACE Note: The BIOSPHERE is an interaction of those other spheres which gives rise to conditions that support life. The living things on the planet comprise the biosphere.
