Understanding Earth's Structure: Crust, Mantle, Core, Landforms, Water, and Atmosphere

Explore the fascinating structure of Earth, including its outermost crust, the rocky mantle beneath, and the solid and liquid inner and outer core. The crust is the thinnest layer, varying in thickness from oceans to mountains. Discover how Earth’s landforms are shaped by geological processes and the role of water, which covers nearly 75% of the planet. Learn about the atmosphere, which sustains life by providing essential gases like oxygen and shielding us from harmful solar radiation.

Presentation Transcript

  1. Earth Structure Swag Jack and Cameron

  2. The Crust • the crust is Earths outermost layer • thinnest layer • thinnest at ocean • thickest at mountains crust

  3. The Mantle • rocky layer • temperatures from 3,300°F • able to flow • solid

  4. Inner and Outer Core • inner core is solid • outer core is hot liquid • inner core is greater than 5,000°F

  5. Earths Landforms • Formed when Crust is pushed up • Formed when worn down by Earth`s surface • Sometimes formed underground • Formed naturally

  6. Water • covers almost 75% of Earth • oceans hold about 97% of Earth`s water • bays, lakes, etc. hold the other 3%

  7. Atmosphere • layering of gases over the Earth • it includes oxygen • makes life possible • Blocks harmful rays of sun
