Chapter 9 : Earth
Across
- 2. Life zone consisting of a variety of life such as humans, animals, plants, and microorganisms
- 5. Earth layer covering the crust and the top part of the mantle, spelled "Litosphere" in the slides
- 6. The outermost Earth layer that is divided into several pieces of plates
- 10. Rock and soil zone on the Earth’s surface
- 11. Rocks from space that survive passing through Earth’s atmosphere and land on the surface
- 13. The atmospheric layer from 0 to 13 km where living organisms breathe and clouds, rain, and snow form
- 17. A vent on the Earth’s crust that allows molten and hot magma to flow out through it in a strong eruption
- 18. Atmospheric layer from 50 to 80 km where the burning and destruction of meteorites occur
- 19. Atmospheric layer from 480 km and above where communication satellites orbit the Earth
- 20. Earth layer situated below the crust consisting of the litosphere, asthenosphere, and mesosphere
Down
- 1. Atmospheric layer from 13 to 50 km that contains the ozone layer and is suitable for aircraft flights
- 3. A stream of colorful lights in the termosphere resulting from reactions of charged particles with Earth's magnetic field
- 4. Exogenic process of rock fragmentation and decomposition due to temperature, rainwater, frosting, and microorganisms
- 6. Inner Earth layer which, along with the mantle, has high temperatures that produce convection currents
- 7. Exogenic process of eroding the Earth's surface by moving agents such as water, wind, and waves
- 8. The mantle layer where high temperatures produce convection currents capable of moving the Earth's crust
- 9. Atmospheric layer from 80 to 480 km that contains ions reflecting radio waves and is where auroras occur
- 12. Air zone covering the Earth’s surface
- 14. Gas found in the stratosphere that absorbs harmful ultraviolet rays from sunlight
- 15. Water zone that includes rivers, lakes, seas, and water trapped as ice, underground water, and water vapour
- 16. Molten and hot rock that flows out through volcanic vents
