Across
- 3. climate change, increase in atmospheric temperature, along with climate changes that have resulted from it.
- 5. circulation, changes in ocean circulation caused by El Nino can also result in short-term climate fluctuations
- 7. activity, over relatively short time scales, fluctuations in the amount of solar radiation can change global climates
- 8. tectonics, geographic changes in Earth's land and oceans due to plate tectonics caused changes in climate over very long periods.
Down
- 1. eruptions, volcanic ash, dust and surfer-based aerosols in the air increase the amount of solar radiation that is reflected back into space
- 2. warming, used to refer specically to the increase in the temperature of Earth's atmosphere near the surface.
- 4. orbital motions, changes in the shape of Earth's orbit and the tilt of Earth's axis of rotation affect global climates over intermediate time scales
- 6. models, complex computer programs that involve huge amounts of data on temperature, precipitation, and other variables
- 9. green house effect, a natural warming of both Earth's lower atmosphere and Earth's surface
