Across
- 2. mineralized remains of organisms (shows how long the dead organisms lived and how their bodies were structured)
- 6. Map showing the shape and elevation of the land surface using contour lines
- 7. solid fragments of weathered rock are eroded (moved) and then dropped into a new place (wind, water, ice, and gravity)
- 9. Solid layer with some plasticity located just below the lithosphere (plates float and move on this layer)
- 10. mechanical or chemical processes that break rocks into smaller pieces
- 11. 1st theory describing the history of Earth’s surface that says the continents were once connected, and have since drifted apart (Alfred Wegener)
- 16. outermost layer of Earth that is divided into enormous pieces called tectonic plates (consists of the crust and top part of the mantle)
- 17. parallel pattern of rock material found at identical locations across the Mid-Atlantic Ridge, reveals rock of the same geologic age (Harry Hess)
Down
- 1. The study of many different kinds of earth science and could be inside or outside of Earth(atmosphere, weather, etc.)
- 3. Maps Photos or images taken of Earth from space
- 4. 2nd theory describing the history of the Earth’s surface that says the lithosphere is divided into plates that are moving on top of the asthenosphere (Dan McKenzie)
- 5. Interval The difference in elevation between two adjacent contour lines of a map.
- 8. Natural physical features of the Earth’s surface (ex: hills, valleys, and rivers)
- 12. the study of Earth’s surface and its features (especially in terms of elevation)
- 13. when a denser plate is pushed down beneath a less dense plate that occurs at a convergent boundary which creates volcanoes and trenches
- 14. distance above sea level
- 15. Process by which water, ice, wind, and gravity remove and transport sediments
